摘要： Active Circulation Control (ACC) of aerodynamic structures, such as a turbine blade, uses unsteady or oscillatory flow from either synthetic jets or pulsed jets to modify a velocity profile of the blade. The blade includes an opening disposed in a surface of the blade at a location proximate to a trailing edge, a leading edge, or both the trailing edge and the leading edge of the blade. An active flow control device in fluid communication with the opening produces a wall-jet of pulsed fluid that flows over the trailing edge, the leading edge, or both the trailing and leading edges of the blade and modify the velocity profile of the blade.

摘要： A wind turbine rotor blade assembly includes a rotor blade having a pressure side, a suction side, a leading edge, and a trailing edge extending in a generally span-wise direction between a tip and a root. An edge extension is attached along either or both of the leading edge or trailing edge in a generally span-wise direction from adjacent the root towards the blade tip, with the edge extension having a contoured outer surface that defines a generally continuous aerodynamic surface. The edge extension has a terminal end that is spaced from root. A curtain is attached to the edge extension and extends in a span-wise direction from the terminal end t to the root. The curtain is formed from a pliant, flexible material that accommodates connection of the root to a rotor hub, as well as pitch movement of the rotor blade relative to the hub.

摘要： A wind turbine blade had a suction side surface and a pressure side surface. A plurality of vortex elements are formed on at least one of the suction side or the pressure side surfaces. The vortex elements have an upwardly inclined wind face and a downwardly inclined slip face, with the wind face and slip face meeting at a generally open-ended U-shaped ridge that defines side horns. The side horns decrease in height from a forward most portion of the ridge to the suction side surface or pressure side surface.

摘要： A method of manipulating a boundary layer across a wind turbine rotor blade. The method includes coupling at least one vortex generator to the rotor blade. The vortex generator includes at least one sidewall that extends outwardly a radial distance from an outer surface of the rotor blade. The vortex generator is selectively positionable between a first position and a second position. A control system calculates a condition of the boundary layer. The vortex generator is positioned at one of the first position and the second position based on the calculated condition of the boundary layer for moving the vortex generator between the first position and the second position.
