Abstract
The invention relates to a flow control device for a wind turbine generator blade comprising at least one flow effector for affecting a fluid boundary layer at said wind turbine generator blade, said at least one flow effector being movable between a retracted position and a projected position. The flow control device further comprises at least one actuator adapted to retract or project said flow effector, said actuator being adapted to communicate with the air pressure on at least one surface of the wind turbine generator blade. The invention also relates to a method of controlling a fluid boundary layer on a rotating wind turbine blade comprising at least one movable flow effector connected with an actuator. Furthermore, the invention relates a wind turbine generator comprising a flow control device according the invention and use of the flow control device.
