Description
The present invention narration produces from moving fluid new equipment and new method firmly, and its a kind of aggressive device that is placed in the motion liquid (for example air or water) of touching upon is in order that produce maximum impetus for the energy consumption of needs effectively.In the navigation field, concrete device of the present invention can be saved the energy, because it utilizes wind-force to promote boats and ships, and other power consumption pushing devices that assistance or substituted ship are used.But, the present invention also is useful at other field and occasion, for example is used for land or vehicle, windmill, turbine, waterpower or wind-driven generator on ice.
The improvement that the present invention invents before being.80, No. 25456 F.P.s that on December 1st, 1980 filed and the application of narrating in 81, No. 06751 additional patents of filing on April 3rd, 1981 are seen in invention in the past, and exercise question is " device that produces transport force at fluid ".For clarity sake, principle of using in the past and structure are also in this elaboration.
Utilizing common sail (passive device) to promote canoe as everyone knows needs bigger sail area, and this has narrow limitation in practice, because the wind-force that is obtained by this structure is directly proportional with sail area.Utilize 1931 not the Lay Tener re-issue " Magnus effect " described in the patent in 18, No. 122 U.S. and obtained the achievement of using aggressive device, as the cylinder of successive rotation.But these devices will be paid very big energy consumption for the driving arrangement of necessity, and mechanism's complexity, and reason is to need the speed of changeing with per minute hundreds of rotating cylinder constantly in order to produce required Driving force.In addition, they are reverse again after must stopping operating when changing direction, and operation is restricted.
Especially it is to be noted, the above invention and present invention of F.P. in the past all is improvement for " wind motor " type, this class wind motor was narrated in 2,713, No. 392 U. S. Patents getting permission July 19 nineteen fifty-five people such as Feng Kaman.And former and present invention has realized great improvement in the output that has firmly, say with respect to the energy Come that consumes in order to obtain useful output, has improved energy efficiency widely.
Total Come says that the present invention and former invention all are to utilize a fixing and orientable hollow body, adopt tubing string shape or cylindrical shape, preferably have special shape of cross section (being section).This hollow body has been arranged the zone (for example aperture) of fluid penetrable specially, from then on sucks fluid in the zone by suitable ventilator or suction device.Adjustable control blade or baffle plate provide other characteristic, can improve the ratio of ouput force to the input energy greatly, and the flexibility that improves this device operation.
In order to understand the present invention better, below discuss about some basic principles shown in Figure 1 in the accompanying drawing, Fig. 1 is the principle schematic of this invention.
Fig. 1 represents to be placed on the device (for example sail on the ship) that M is ordered in the fluid (for example air), the fluid speed of this device relatively is V, device is subjected to a directed force F, this power can be decomposed into one perpendicular to the driving force P of liquid velocity vector V and with the unidirectional tractive force R of velocity vector V.If this device is pressed direction A at M and is moved, form inclination alpha with velocity vector, it just is subjected to the effect of a propelling force T, this power is equivalent to the projection of driving force F on direction A, therefore, for a certain size inclination angle (between wind direction and ship's head), when α spends less than 90, the size of propelling force T increases with the increase of driving force P, and tractive force R then reduces.
Usually, driving force and tractive force are represented with nondimensional coefficient Cz and Cx, try to achieve by following formula:
P is driving force (being equivalent to aerodynamic lift) in the formula, and R is a tractive force, and ρ is the density of fluid, and V is the speed of fluid, and S is this device proj ected surface areas on perpendicular to the plane of fluid motion direction V.C
ZAnd C
XBe lift and the tractive force (C that is applicable to aerofoil as everyone knows
LAnd C
D) coefficient.
Consider these representations, obviously propelling force T can be represented by the formula:
T＝ 1/2 ρV
2S（C
ZSinα-C
XCosα）
This formula clearly illustrates that, for the orientations of certain liquid speed V and propelling force T, S and C
ZProduct big more, then propelling force also will subtract greatly.
If these results are applied to not want the conventional apparatus that outside supplying energy produces driving force (aircraft wing for example, sail on the ship, the blade of windmill or sail, or the like), then coefficient Cz in fact always is lower than 1.7, but wing for flapped aircraft, may be 2.2, be 2.7 for super supportive device, obviously, the surface area that produces high Driving force T needs is too big, and is therefore inconvenient in practicality.
Known and adopted a kind of aggressive device Come of external energy that utilizes to produce very large driving force P or lift coefficient Cz, for example, according to the so-called Magnus effect of narrating in the patent of above-mentioned not Lay Tener, rotating a cylinder (around its axle) and places it in the fluid, fluid flows around this cylinder, the deflection of fluid stream produces a very big power to this cylinder, and its direction depends on the speed and the direction of cylinder rotation.The rotation of cylinder is also postponed and has been reduced the numerical value of fluid stream with the end mobility that separates and obtain of drum surface.
Though Magnus effect might produce high coefficient Cz numerical value, the peripheral velocity that produces the required cylinder rotation of result like this causes mechanism quite complicated, and needs sizable power; Should be noted that for example size of cylinder, its diameter must be 3 meters, and 15 meters of height can promote a smaller ship (promptly 30 meters long).The machinery complexity is special is related with wave, gyroscopic effect etc., and these effects when wind speed is high, can reach 400 rev/mins necessary rotational speed owing to the such cylinder of rotation produces.In addition, when using this device promotion canoe or steamer, if wish to make propelling force reverse, obviously must make the cylinder counter-rotating, because effect of inertia, counter-rotating needs considerable time.
Feng Kaman has proposed to overcome the way of above-mentioned some shortcoming in 2,713, No. 392 patents of the nineteen fifty-five U.S..Suggestion adopts a fixing vertical cylinder promotion ship to advance aboard ship in patent, and cylinder is permeable to air, and air is inhaled in the cylinder, and air stream is flowed around drum surface.The inflector of a weak point makes the air-flow that has separated around the cylinder that the path of different length be arranged, and causes producing transverse force and acts on this cylinder.But coefficient Cz does not surpass 2.4 in the wind tunnel test process of this structure France before two more than ten years, so that install impracticable.Similar principle even in 222, No. 845 patents of Britain of distribution on May 7 nineteen twenty-five, also proposed (NVInstituut Voor Aeroen-Hydrodynamiek) in theory, but fail to make practical structure.
Summary of the present invention
The objective of the invention is to provide a kind of driving force very large aggressive device, C
ZFrom 5 to 6, the external energy that needs is minimum, does not have the shortcoming of device in the past, for example utilizes the Magnus effect rotating cylinder.Obviously, device can be used for many aspects made in accordance with the present invention, for example promotes a moving object (for example ship), perhaps produces useful mechanical energy from fluid motion, and mechanical energy can be transformed into electric energy by generator again.The present invention not only can acquire an advantage from wind energy, and can be from the river, ocean current, tidal flow so that acquire an advantage in any fluid stream (for example in turbine).Though the present invention also is fit to the fluid of non-air, will set forth in view of flow (wind) of air below, the driving force of wind can be suitable with the lift of aerofoil herein.
Though the basic physical principle of utilization of the present invention is equivalent to the aerodynamic principle of plane airfoil (being wing or helicopter blade) a little, the condition that these principles are used is diverse, and has any different with aerofoil.The present invention is for low flow velocity particularly useful (for example being lower than 50 nautical miles), and plane airfoil relates generally to very high speed.In addition, aerofoil is main relevant with maximum lift, ignores the energy saving problem basically.On the contrary, in the present circumstance, what mainly consider is power saving, for energy consumption, produce maximum driving force.Moreover the aerofoil design is closely related with the tractive force factor, and does one's utmost to make lift coefficient (C
LOr C
Z) and tractive force (C
DOr C
X) ratio the most reasonable.In contrast, tractive force here is unessential, especially navigation purposes, and the resistance that passes the water motion at this occasion hull makes fluid inessential to the tractive force that advancing means produces.
Under the aerofoil situation, the coefficient scope of lift is 0.2 to 0.3 in the course of normal operation.This numerical value can increase to 2.5 to 3.0 when wing flap was expanded in landing mission.Coefficient of tractor C
XBe 0.01 the order of magnitude, make the ratio of Cz and Cx suitable.
Cz value provided by the invention but is 5 to 8, and this is that driving force meets the requirements of index.Efficient changes the energy Come tolerance that driving force consumes, an available energetic coefficient (C into according to the fluid circulation
A) characterize.This numerical value is nonsensical for the aerofoil of aircraft.
In the present invention, reasonable energy consumes C
AShould be to be lower than 0.2.At C
AIn from 0.1 to 0.2 the useful scope, the Cz value (being equivalent to driving force) that the present invention produces is from 5 to 8, the numerical value that reaches far above plane airfoil.
The present invention advises that a device is placed in the fluid that moves by first (fluid) direction, in order that produce driving force in second (driving) direction, second direction is transversal with respect to flow direction.This device comprises an elongated hollow body (for example pipe, cylinder or conical column), this hollow body has the cross section (being section) of a circle on the flow direction plane, this cross section is symmetrical in symmetry axis, and this symmetry axis has been stipulated the inclination angle of convection cell direction.When being used for boats and ships,, must make section and all accessorys (for example following aperture or baffle plate) all have a symmetry properties in order to utilize the wind-force of Come from the ship both sides.Section preferably has an elongated head and an afterbody, and the width of head increases from front to back, and the width of afterbody then reduces from front to back.This section is " thick ", promptly between 50% and 100% of the symmetrical axial length of section Extreme breadth Jie.
Especially, the tail shape of this section partly is a circular arc less than hemicycle, and all the other essence are part ellipses (more than half ellipse), link on this circular arc smoothly.This device also comprises the equipment that the control surface fluid boundary layer flows, controlling method preferably by produce at body surface that sizable pressure falls or vacuum (for example, going up the fluid penetrable district by this surface sucks), to produce sizable pressure in a certain zone of horizontal that side of driving force indication of section afterbody (face with the wind) at least and fall or vacuum.At afterbody the two kind fluid streams of other device in order to separated body outer surface both sides are arranged, this equipment is positioned at a side of facing fluid flow direction, i.e. windward side.
These characteristics of the present invention help to make the pushing device that is easy to realize, and can produce useful huge driving force, and energy consumption is especially little.
These advantages cause abandoning the original characteristics and the elongated especially shape of section head of thick symmetric body section, and the infiltration area that produces the suction effect might be limited on the very little zone on the section, need the energy that consumes thereby reduce this device widely.So, have only when the speed of (with the wind) fluid boundary layer on this external surface makes that the air stream trend is left surface and turbulization, working as pressure gradient in other words is timing, just is necessary to produce suction effect (i.e. suction).But, have found that, this special elongated shape of the section head of section (especially) might stop this situation significantly, thereby will provide the outer surface flow region of suction effect necessity to be restricted to smaller scope, and restriction sucks the degree of vacuum of flow velocity and body surface.
According to the present invention, the significant especially performance of this device also Come is gone into body generation high vacuum or high pressure drop from the combination of the special thick section of suction equipment and body so that inhale fluid in the infiltration area.The shape of section also is favourable, because this shape provides an enough big suction chamber, make internal pressure reduce to very low level rapidly, thereby reduced the loss of the motion of air, this helps the energy consumption that reduces flow losses and be used for this device.
In addition, blade or baffle plate (promptly not having any other energy consumption) by special device and sizing, outer (with the wind) and interior (facining the wind) lip-deep fluid flows around separating hollow body, can prevent to form parasitic eddy currents and turbulent flow, otherwise energy input one regularly will make driving force reduce.
Obviously, some characteristics of apparatus of the present invention will could obtain surprising using effect in conjunction with playing Come.For example, when the proj ected surface areas of body is 150 square metres, motor with one 90 horsepowers vacuumizes, and wind speed per second 12 meters (24 nautical miles/hour) just can promote the ship of 14 nautical miles/hour of a maximum speed under vantage, and angle α is about 60 degree between moving direction of shipping and the wind direction.In order to obtain same result, the surface area of sail must have 1000 square metres, and this certainly will increase the overall dimensions of ship greatly, and operates required number of this sail and equipment.
In order to illustrate that the energy-saving benefit that utilizes device of the present invention to obtain should be noted also that in last example, to equip at ship under the situation of common propulsion apparatus, the performance according to device of the present invention is pointed out hereinbefore needs about 1200 horsepowers motor.
Point out at last, adopt the device that relative hull is maintained fixed, obviously can exempt and utilize Magnus effect rotating cylinder device and with the mechanical failure of Come.
Another characteristics of the present invention are, the device of automatically adjusting body section symmetry axis can be provided, and making it has suitable inclination angle with respect to flow direction.
In fact, according to the present invention, the section of this slender body has an afterbody less than the circular arc of hemicycle, and the remaining part of section is oval, greater than half ellipse, links to each other with circular arc smoothly.
Elongated head practical structures is streamlined, and its cross section is an oval part.
In order to guarantee that this device is placed on unlikely damage in the much higher fluid of velocity ratio normal speed, can improve the intensity of device, perhaps adorn contractile parts at least at its elongated head, can reduce the total surface area of body like this.
Other characteristics of the present invention are to it is contemplated that various structure for contractile parts.If this slender body afterbody has a rigid cylinder shape shell, just can make head: flexible, the inflatable shell of list or double-walled with following method; With respect to the activity hoop that cylindrical housing can move radially, link on the shell with flexible diaphragm; Be placed on the flexible beak-like protrusion between two holders, holder for example is bar or rope, and they are arranged essentially parallel to the axle of barrel shrond, and produces the effect in gap; Category of rigid is like the protrusion of beak, and it can move radially with respect to shell.At last, this slender body assembly is telescopic, and many rigid elements are arranged, and made by flexible material at least one, so its length can shorten arbitrarily.
Obviously, these characteristics can be improved the performance of this device under disadvantageous high flow rate operational condition.Then in office what is the need for all can reduce the water cross section of body in the moving fluid when wanting because elongate head has stretchability.
Equipment in the control of face with the wind boundary layer can be combination or the equipment that separates, for example inhales the ventilator that fluid is gone into hollow body, and/or enters the equipment of outer surface fluid stream according to the direction blowing fluid that is cut in hollow body.
The equipment that outer surface and internal surface fluid flow point are opened can be baffle plate or the blade that protrudes on the hollow body surface, or fluid is blown out Come and place the equipment of outer surface fluid stream in hollow body, tilts at flow direction.Baffle plate can be straight or aduncate, and blowing apparatus can be radially, inclination or tangential, and interrelates with baffle plate, so that quicken near flowing of the outer surface fluid baffle plate.
In order to make the driving force can be reverse, it is two that various members all become, and when a members contract or when damaging, another member is in work, and the two all is symmetrical in the symmetry axis location of hollow body.Otherwise equipment can be single component form, can shift to the both sides of hollow body symmetry axis.
Another characteristics of the present invention are, at each end of hollow body end plate or suitable structure are arranged preferably, to limit disadvantageous boundary vortex or turbulence effect.In order further to improve the efficient of device, each end plate can have a circular portion, presses the direction rotation of outer surface fluid stream; Perhaps have to suck or blowing apparatus, these equipment are tangential, vertical with respect to end sheet surface or tilt.
The combination economic especially according to these different characteristics set up vacuum in its surface with the pumping equipment in the slender hollow body, with blade or the baffle plate separation inboard and the outer surface fluid stream of radially arranged on the slender body, is furnished with end plate in the slender body end.According to concrete device of the present invention, pumping equipment has a ventilator at least, and its axle is parallel to the longitudinal axis of slender body.Ventilator is placed in the hollow body, respectively near the end, enters in the hollow body so that between two ends, can both aspirate fluid on the whole distance, and, by each end plate fluid that blows side out outwardly.This scheme is particularly suitable for telescopic slender body.But it also is applicable to every other streamlined structure.Be preferably in the peripheral circular arc of each end plate and afterbody side from radially blowing.The blowing cross section is enough big so that reduce drop of pressure, otherwise can increase energy consumption.
Another concrete structure of the present invention is dividing plate longitudinal extension in slender body to be arranged, in order that separate two intervals that are interconnected by the circle opening.Ventilator is positioned on these openings, one of fluid suction is had in the interval of suction district, and it is blown in another interval that blowing district is arranged, and places near the fluid stream of baffle plate.The axle of ventilator is preferably perpendicular to the section symmetry axis that dividing plate is housed.In order to make driving force reverse, two suction districts and two blowing districts are provided, arrange with respect to section symmetry axis symmetry; And the equipment that the infiltration area is used that covers is provided, these infiltration areas are inconsistent with the direction of the driving force of wishing to produce.There is the swivel plate that constitutes on the hollow surface infiltration area, can open towards the hollow body inboard; Blowing apparatus has the swivel plate that constitutes on the hollow surface, can open towards the hollow body outside.In this structure, suction and blow-down panel alternately open and close, as ventilator operating work usefulness, and the at interval step-down that produces of both sides ventilator or machinery or find time and the superpressure function.

The detailed description of best concrete device
Just as described above, the present invention includes a device that is fit to be placed in the fluid stream that flows with speed V, it is thick and the symmetrical circular section that this device preferably has an elongate tubular body, the cross section on direction of fluid flow, its head is elongated, has special shape.But for simple declaration principle of the present invention, the body 10 with circular section on Fig. 2 a is represented.Being drawn as circular section only is in order to explain that the shape of similar Fig. 8 described below is preferably arranged according to present invention.
Shown in Fig. 2 a, the fluid stream (for example wind) with speed V is moving along the X-X ' axial flow of this section.X-X ' has a transverse axis y-y ', and this section is divided into four quadrant 10a, 10b, 10c and 10d, is appointed as first respectively and is limited to four-quadrant.Quadrant 10b and 10c form the head of section, at first be subjected to the impact of fluid stream, and quadrant 10a and 10d are the afterbody of section.Fluid stream will be divided into two bundles shown in Fig. 2 a, and this two bundle is the outside (with the wind) fluid stream 11 and inboard (facining the wind) fluid stream 13.Laterally providing synthetic rising type driving force P(Fig. 1 on the y-y ' in order to produce pressure difference to slender body 10), two main features are arranged.
In 12 arrangement on the schematic representation is to produce vacuum or pressure falls in hollow body 10 with Come, main in the quadrant 10a of section, (is illustrated in the upside of figure) on the face with the wind of section afterbody.The step-down method is to arrange the fluid penetrable district 54(of a β angle size for example with holes at the wall of hollow body 10), and load onto pumping equipment in vivo as ventilator and so on, in fluid suction hollow body 10, as described below.The air stream 11 that is positioned in permeable district 54 normally separates part with the hollow body surface.Permeable district 54 and pumping equipment keep air stream 11 to flow around the outer surface of this section with Come, and turbulent flow is minimum.In addition, second line body stream is around another (inboard) Surface runoff of this section.
For the outside at hollow body 10 separates outer side liquid stream 11 and interior side liquid stream 13, blade or deflecting plate 14 are provided.Blade 14 also is contained in the afterbody of section, but in interior (facining the wind) side (being quadrant 10d) of afterbody, corresponding with permeable district.
As shown in Figure 1, this being arranged in produces a driving force P on y-y ' direction, be transverse to the direction of rate of flow of fluid V.If device M regards an aerofoil among the wind V as, power P is exactly a climbing power so, and R is the tractive force to aerofoil.For the consumption of energy minimum, the lift coefficient Cz numerical value that characteristics of the present invention produce is situated between between 5 and 8.
The structure of Fig. 2 b is different with Fig. 2 a, except that baffle plate 14a, for separately the outside and inboard fluid flow apparatus 14 comprise the device of representing with arrow 14b, in order to fluid from radially blowing to body 10 outsides, 14b is positioned near the baffle plate 14a, on the face with the wind of baffle plate 14a, outer side liquid stream appears herein.
Not in the modification structures of this expression, baffle plate 14a can be crooked inwardly, causes concave surface on the outer surface of fluid stream according to another kind.Blowing apparatus is to act on the direction that is cut in hollow body 10 basically, and according to the directive effect of outer surface fluid stream.
Modification structures Fig. 2 c has the parts among Fig. 2 a, but after being added with equipment 12, in order in first quartile 10a, to produce vacuum, also has blowing apparatus, on figure, represent with arrow 12b, the tangential effect of 12b section between pumping equipment 12a and baffle plate 14a, and according to the directive effect of outer surface fluid stream.
According to herein not the expression another device, Fig. 2 b and Fig. 2 c form characteristics can in conjunction with.By same quadrat method, several tangential blowing apparatus resemble 12b can be used between pumping equipment 12a and the baffle plate 14b.
In another modification structures of not representing, adopt the equipment that resembles the blowing of this class of 12b among Fig. 2 c to produce degree of vacuum usually herein, act on the mobile stream that flows around first quartile 10a.Obviously, this modification structures can combine with any various modification structures that are used for separating the equipment 14 of outer surface and inner surface fluid stream.
Fig. 2 d represents another modification structures of the present invention, according to this configuration, do not comprise baffle plate in order to the equipment that separates the outside and inner surface fluid stream, only use blowing apparatus 14c, it is generally in the four-quadrant effect, along the direction that is cut in hollow body 10, fluid is blown to the outside at inner surface fluid stream place from hollow body 10, and along the direction of inner surface fluid stream.
Therefore, adopt any the said equipment, especially adopt aspirator 12a, can make outside fluid stream fall direction and move along the vacuum of section or pressure, as Fig. 2 a to shown in the 2d.
Characteristic feature of an invention before Fig. 3 represents, according to this invention, body 110 has a thick and circular section, is symmetry axis with XX '.More particularly, as shown in Figure 3, the section of body 110 has an elongated head 110a, and its thickness increases in the past backwards; And an afterbody 110b is arranged, and its thickness reduces in the past backwards.If e is the Extreme breadth of section, the 1st, length or chord, e/1 is a bit larger tham 0.5 so in this case, may be between 0.5 and 1.00.
Use this section, can improve driving force P for direction of fluid flow (being wind direction) inclination Come by section symmetry axis XX ', the angle of inclination is i.The elongated shape of section head has postponed the fluid format body of wandering about as a refugee, and can reduce the area of infiltration area 54, thereby has reduced the pumping power that needs.Fig. 3 represents a kind of device that infiltration area 54 and baffle plate 14a are arranged, as Fig. 2 a.This arrangement can make driving force P and the ratio the best of aspirating power consumption.
In Fig. 3, the device 14 that separates two kinds of surfactant fluid streams 11 and 13 with Come is the radial flat baffle plate 14a of rigidity that are arranged in these 110 outsides.Because coefficient Cz increases with baffle length, so the length of baffle plate 14a is that R/2 is the radius of body 110 semicircle afterbodys to R(R), exceed the essentially no superiority of this scope.Perhaps baffle plate 14a extends under the minimum point of section, as shown in Figure 3.It is said that this arrangement is to following situation advantageous particularly: the infiltration area is positioned at the outer side liquid format body part of wandering about as a refugee, and promptly begins part near afterbody 110b on Fig. 3 outer surface.This position is between OX axle 65 degree and 150 degree (the 0th, the center of circle of shell 110 sections, angle is measured in the direction of the clock).Infiltration area 54 as shown in Figure 3 in addition can be reduced to 45 the degree the β angles, the center line at β angle from the OX axle about 110 the degree, so the infiltration area from distance OX axle 85 spend to 130 the degree.In other words, infiltration area 54 expanded ranges chord 60% and 90% between, the edge meter rises from the head.
The degree of permeability of infiltration area 54 fluid flow (being porosity) needn't be identical always, but can regulate, preferably be chosen between 20% to 30%.Infiltration area 54 can have two or more zones that separate to be located in the above-mentioned angular range, it is said to be favourable under limited suction turnover rate situation.The internal pressure that will produce in body 10 or 110 is that external pressure deducts and passes after infiltration area 54 and other flow losses low numerical value like that at least.In order to save energy, pumping power is only limited to the power that the suction fluid boundary layer needs.
Baffle plate 14a is preferably with respect to OX ' axle inclination (being positioned at the offside of infiltration area 54, i.e. the windward side).As between 35 and 45 degree, can obtain high coefficient Cz value with respect to the inclination angle of OX '; As between 15 and 25 degree, then can improve lift coefficient Cz and coefficient of tractor Cx maximum ratio.Single baffle plate 14a is best, as described belowly makes movablely, and it can be from a side of XX ' axle to opposite side, and the direction that applies driving force with hope is consistent.
More than can separately or unite and be used for Fig. 3 shape with the various suction schemes of figure explanation.Fig. 4 a is the example that other is represented the scheme of aspirating to 4d, mainly produces vacuum or pressure drop at first quartile 10a or four-quadrant 10d, and the direction that provides driving force with hope is consistent.These schemes can prevent that body surface the afterbody thin outside (promptly with the wind) fluid stream or boundary layer from separating.And restriction turbulent flow.
For this reason, Fig. 4 a and 4b represent that body 10 can comprise fluid penetrable shell 101 and impermeable shell 102, and the latter has a kerf 16, accounts for the part of its circumference, and kerf width defines the infiltration area angle beta (referring to Fig. 2 a).In the concrete device of Fig. 4 a, permeable shell 101 is placed in the outside of impermeable shell 102, but opposite in Fig. 4 b.Permeable shell 101 can be a porosity or wall with holes or net, grid, seam slit etc.β angle, infiltration area is at first quartile, but also may extend into second quadrant, reaches the wide of 25 degree approximately.If driving force is when reverse, this situation just conversely, the infiltration area might extend to third quadrant at four-quadrant.So, fluid impermeable shell 102 is made orientable so that otch 16 can be moved into four-quadrant from first quartile.
The modification structures of Fig. 4 C is the improvement of Fig. 4 a and 4b structure, can regulate the β angle in operating process.For this reason, in fact fluid impermeable shell 102 is made up of 103 and 104 two shells, and wherein at least one is orientable.Therefore, if 103 pairs of XX ' axisymmetric then just can change the width of otch 16 and otch is moved on to the body bottom from body top (seeing figure) as scheming mobile shell 104 shown in last 116, perhaps move on the contrary.
As the direction of desire change driving force, the distressed structure of Fig. 4 d just can be adjusted the infiltration area and the baffle plate of work simultaneously in once-through operation.By this form, hollow body 10 comprise a fixing inner casing 105(remove infiltration area 54 and 54 ', it is impervious) and orientable, impermeable shell 106, the latter as a cover plate or valve can move with covering infiltration area 54 or 54 '.
According to a kind of modification structures of expression not herein, the lock formula can be made in the infiltration area on body 10 shells, and opening side within the body 10.
If driving force wants oppositely (when fluid changes direction) will exchange the quadrant position in baffle plate 14 and district with holes 54 so.Fig. 5 a and Fig. 5 b represent two kinds of modification structures of baffle plate, all can be used in Fig. 3 device with reach baffle plate 14 first and four-quadrant between the purpose put upside down.Shown in Fig. 5 a,, be arranged in XX ' axle both sides symmetrically according to the inventive system comprises two radial flat baffle plate 14a and 14b.Just as can be seen, baffle plate 14a, 14b all can be withdrawn into respectively among radial gap 18a, the 18b, so that in the body of withdrawing fully.More specifically, when one of them stretched out as baffle plate 14a and 14b, another baffle plate is withdrawal just; Vice versa.This helps driving force P reverse.
Fig. 5 b represents the another kind of structural type of baffle plate, and as the modification structures of front, two baffle plate 24a, 24b arrange with respect to XX ' axisymmetric.Each baffle plate is positioned on the body 10 rotationally along the bus 20 of body 10.It just can forward to downwards above the body 10 like this.Baffle plate has a flat or crooked shape inwardly, and is identical with the section of body 10, and unlikely prevention fluid stream flows around body 10.In Fig. 5 a structure, a baffle plate 24b is poured on the body 10, and another piece 24a is in running state, and perhaps opposite, the direction that applies Driving force with hope is consistent.
Fig. 5 c represents another modification structures, have a flat radial baffle plate 34a to be positioned on the body 10, it can move around the axle of body 10, so it can be adjusted aspect angle, and can the 4th and first quartile between move, consistent with the direction that applies driving force.
Can adopt other baffle arrangement.Particularly the baffle plate of two expansions alternately expands with respect to XX ' axisymmetric location, and the direction of setting up driving force with this device is consistent.
Vacation is blowing apparatus 14b(Fig. 2 b radially or radially), when quickening outer surface fluid stream its act on as if inside and outside side surface fluid stream between a baffle plate.Sham cut to or tangential blowing apparatus 12b, 14c(Fig. 2 c and 2d) carry because to the friction of the body 10 walls thin fluid stream of degradedness, and carry because the fluid fluid layer that response facilitation effect causes.
Modification structures Fig. 5 c can be used for Fig. 4 d, as shown in Figure 6.The same Fig. 3 of the shape of body 10 has a semicircle afterbody 110b and circular elongated head 110a herein, infiltration area 54, and 54a makes on body 10, is symmetrical in XX ' axle, and position and size front have explanation.Be equipped with a circular-arc shell in body 10 outsides or valve 106(sees Fig. 4 d), can move to regulate the angular range of an infiltration area 54 or 54a, block another infiltration area this moment, shown in Fig. 4 c and 4d.So baffle plate 14a is positioned on the center of valve 106 arcs, can move simultaneously.Like this, if with 106 and the 14a assembly move first quartile or opposite from four-quadrant, just can change the direction of driving force.
Fig. 7 represents to be used for another section 210 of said structure.In this case, head 210a is a half elliptic, smoothly links to each other (as Fig. 6) with semicircular afterbody 210b, and the diameter of semicircle equals oval short diameter.In this example, oval breadth length ratio is about 0.5, and promptly oval short diameter is about 0.5 times of long diameter, so the total-width ratio of section is about 0.66.
In Fig. 6, the infiltration area 54, the 54a that have two symmetries to arrange.These regional extents between distance OX axle 85 degree and 130 degree, porosity 20% and 50%, optimum value is about 30% to 40%.Baffle plate 14a is loaded on the valve 206 of circular arc, and this valve can be regulated so that select the quadrant of baffle plate 14a and set up its inclination angle, can also block unwanted infiltration area, and the infiltration area of will working moves to 54a from 54, and is perhaps opposite.
Fig. 8 represents to have found that according to the section 310 after the present invention's improvement this section has improved 20% with respect to the form among effective driving force ratio Fig. 7 of energy consumption.By this form, section 310 also is to be symmetrical in XX ' axle, and it is circular arc AB that its afterbody 310b has only part.The part (greater than half ellipse) that the remaining part of afterbody 310b and whole head 310a are preferably oval, AB smoothly links to each other with circular arc.Best form is that circular arc AB is symmetrical in OX ' axle, is 90 degree facing to center O.Center O and head 310a distance between two tips account for 74% of total length profile, and the radius of circular arc is 26% of a length profile.It is that 0.66 ellipse draws that this section can be thought by a long diameter ratio of weak point, but connects one section 90 degree circular arc in elliptic end.Baffle plate 14a is positioned at from OX ' axle 35 degree places.Valve 306 can be above-mentioned circular arc, provides suitable conventional seals when needing between it and body 310.Also the shape of valve can be made consistently with its section of laying part, promptly be ellipse arc but not circular arc.Other valve design also can be adopted.
The layout of Fig. 8 also has the advantage that reduces the infiltration area.Porosity for about 45%, the scope of infiltration area (on being projected in XX ' axle time) is counted by head is most advanced and sophisticated, from accounting for 75% to 91% of length profile.And in Fig. 7, the range distance tip of infiltration area is about 63% to 88% length profile.The less further pumping equipment that reduced in infiltration area reduces the required power of body internal pressure, thereby has saved energy consumption.
