B) centerbody 103 of air mechanics contour, it is in turbine 102 and be mounted to this turbine 102;
C) turbine stage 104, and it surrounds centerbody 103, and comprises: the track ring 106 with stator vanes 108a; With the rotor with rotor blade 112a 110.Rotor 110 in the downstream of stator vanes and with stator vanes " in line ", that is, the leading edge of impeller blade is alignd with the trailing edge of stator vanes basically, wherein:
I) stator vanes 108a is installed on the centerbody 103;
Ii) rotor blade 112a is mounted and is maintained at together through inside and outside ring or the inside and outside hoop that is installed on the centerbody 103;
D) show the mixer shown in 118 greatly, this mixer has the lobe of mixing 120a ring on the stub area (that is, the end) of turbine 102, wherein, mixes lobe 120a and extends beyond rotor blade 112a downstream; And
E) show the sparger shown in 122 greatly, this sparger comprises ejector shroud 128, and this ejector shroud 128 is surrounded the mixing lobe 120a ring on turbine, wherein, mixes lobe and (for example, 120a) extends and get into the inlet 129 of ejector shroud 128 downstream.
As shown in Figure 2, the centerbody 103 of MEWT100 is connected to turbine 102 via track ring 106 or miscellaneous part ideally.This structure is used to eliminate traditional wind turbine produces harmful, bothersome and low-frequency sound that propagation length is long when wake flow (wake) the bump support tower of turbine bucket.The air mechanics contour of turbine 102 and ejector shroud 128 is that the aerodynamics curved surface is to increase the air-flow through turbine rotor.
The claimant calculates, and best in order to make efficient, the area of eductor pump 122 is than the scope at 1.5-3.0, and the discharge area that is defined as ejector shroud 128 of said area ratio is divided by the discharge area of turbine 102.The quantity of mixing lobe 120a is between 6 to 14.The interior trailing edge angle of each lobe and outer trailing edge angle are between 5 degree and 65 degree.Just as in this that kind that will further specify, these angles measure up to the line of the central axis that is parallel to turbo machine from the tangent line of drawing in the outlet port of mixing lobe.The main lobe exit position is at the entry position of ejector shroud 128 or 129 places that enter the mouth, perhaps in the entry position or enter the mouth near 129.The depth-width ratio of lobe passage is between 0.5 to 4.5.The penetration of mixer is between 50% to 80%.The trailing edge angle of centerbody 103 stoppers is below 30 degree.The length-to-diameter of whole M EWT100 (L/D) is between 0.5 to 1.25.
By the claimant theory analysis that is the basis with first principle that preferred L EWT100 carries out is shown: under the identical situation of wind-exposuring area (frontal area), the power that this MEWT can produce is more than three times of corresponding intrument of no outer cover; And this MEWT100 can make the productivity of wind energy turbine set (wind farm) improve more than the twice.Based on this theory analysis, believe that MEWT mode of execution 100 is three times of the existing power that produced of traditional open type blade wind turbine of same size with the power that produces.
The gratifying mode of execution 100 of MEWT comprises: axial flow turbine (for example; Stator vanes and impeller blade); This turbo machine is surrounded by the turbine 102 of air mechanics contour, and this turbine 102 has comprised mixing arrangement in its stub area (that is end); Independently ejector shroud 128, and its covering zone endways includes the turbine 102 of mixing lobe, but has just covered the afterbody of turbine 102.Mix the ring 118 of lobe 120a and the combination of ejector shroud 128 and can be regarded as the mixer/educator pump.This mixer/educator pump for make the wind turbine operational efficiency stably surpass shellfish now the limit means are provided.The outlet reference angle of stator vanes (exit-angle incidence) can mechanically change (that is, fin pivots) in the original place adapting to the rate variation in the fluid stream, thereby guarantees that the remaining whirlpool from the air-flow that rotor comes out is minimum.
If describe with different modes; MEWT100 comprises the turbine stage 104 with track ring 106 and rotor 110; Track ring 106 is installed on the centerbody 103 with rotor 110; And surrounded by turbine 102, on turbine 102, be embedded with and mix lobe 120a, the trailing edge of this mixing lobe is inserted the inlet face of ejector shroud 128 slightly.Turbine stage 104 structurally is connected with the turbine 102 of the main load-bearing member of conduct with ejector shroud 128.
These figure have described the rotor/stator assembly that is used to produce power.Term " impeller " thereby be used for refers to that generally blade is installed in axle and goes up and can rotate any assembly that allows to produce from the wind that makes blade rotation power or energy here.Exemplary impeller comprises propeller cavitation or rotor/stator assembly.The impeller of any kind all can be enclosed in the turbine 102 in the wind turbine of the present disclosure.
In some embodiments, the length of turbine 102 is equal to or less than the maximum outside diameter of turbine.In addition, the length of ejector shroud 128 is equal to or less than the maximum outside diameter of ejector shroud.The outer surface of centerbody 103 has air mechanics contour, so that the airflow breakaway in MEWT100 downstream (flow separation) effect minimizes.Centerbody 103 also can be configured to be longer than or be shorter than turbine 102 or ejector shroud 128, or the pattern length of turbine 102 and ejector shroud 128.
The inlet area of turbine and discharge area are equal to or greater than the area of the annular that is occupied by turbine stage 104, and just to need not be circular to shape, so that allow to control better the bump of the wake flow of air flow source and air flow source.The cross-section area of the internal flow path that is formed by the annulus between the internal surface of centerbody 103 and turbine 102 is aerodynamic shape; Thereby (the plane of the turbine) locates to have minimum area on the turbo machine plane, perhaps causes from its each plane of inlet with additive method gently to be changed to its pelvic outlet plane.The outer surface of turbine and ejector shroud is aerodynamic shape, gets into the turbine inlet, eliminates from the airflow breakaway on the surface of the surface of turbine and ejector shroud and help smooth-going gas delivery is got into sparger inlet 129 to help steering flow.The area of the inlet that can replace with non-circular shape of sparger 128 is greater than the area of mixer 118 exit faces; And if expectation, the exit region of sparger also can be a non-circular shape.
When near the residential belt, using, MEWT100 can have sound absorptive material on the internal surface that is fixed in its outer cover 102,128 with the sound wave of the relative high frequency that absorbs and eliminate thus the interaction by stator 106 wake flows and rotor 110 and produce.MEWT100 also can comprise the blade contained structure that is used for add-on security.MEWT also should be regarded as horizontal axis wind turbine.
Fig. 3 to Fig. 5 illustrates second illustrative embodiments 200 of the wind turbine that has outer cover.Turbo machine 200 uses propeller-type impeller 142 to replace the rotor/stator assembly shown in Fig. 1 and Fig. 2.In addition, can more be clear that the mixing lobe in this embodiment.Turbine 210 has two groups of different mixing lobes.With reference to Fig. 3 and Fig. 4, turbine 210 has the high energy mixing lobe group 212 that the central axis towards turbo machine extends internally.In this embodiment, turbine is depicted as and has 10 high energy mixing lobes.Turbine also has away from the outward extending low energy of central axis mixes lobe group 214.Turbine 210 shows 10 low energy equally and mixes lobe.Around the trailing edge of turbine 210, high energy mixing lobe mixes lobe alternately with low energy.As shown in Figure 4, see that the trailing edge of turbine can be regarded as has circular crenation shape from the rear.It is this common upwards downwards or inwardly to shape that term " crenation shape " or " castle shape " are meant trailing edge.
As shown in Figure 5, the inlet area 232 of ejector shroud 230 is greater than the discharge area 234 of ejector shroud.Should be understood to, inlet area is meant the whole oral area of ejector shroud rather than the annulus area between ejector shroud 230 and turbine 210 of ejector shroud.Yet, illustrating in addition like this paper, the inlet area of ejector shroud also can be less than the discharge area 234 of ejector shroud.As what expect; The inlet area 232 of ejector shroud 230 is greater than the discharge area 218 of turbine 210; Mix lobe and, can get into sparger so that hold through this annular section high energy air so that between turbine and ejector shroud, make up annular section 238.
Mixer-injector designs notion in this explanation can improve flow dynamics significantly.These mixer-ejector systems provide a plurality of advantages that are superior to legacy system, such as: short sparger length; Get into and pass through the mass air flow of the increase of system; The low sensitivity that inlet air flow stops up and/or do not aim at main airflow direction; The aerodynamics noise that reduces; The thrust that increases; And the swabbing pressure of primary outlet place increase.
As shown in Figure 6, another illustrative embodiments 260 of wind turbine can have ejector shroud 262, and this ejector shroud has and forms the interior muscle that wing plate or fin 264 are provided.Wing plate or fin 264 are oriented to be convenient to wind turbine 260 and to aim at raising energy or power generation with the air-flow that gets into.
