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...
1. A wind turbine comprising: a wind turbine blade comprising an opening disposed in an outer surface of the wind turbine blade proximate a curved trailing edge of the wind turbine blade, andactive flow control devices disposed in the wind turbine blade and in fluid communication with the opening and configured for producing unsteady wall-jets of pulsed fluid that flows over the curved trailing edge, wherein the unsteady wall-jets of pulsed fluid comprise velocities and frequencies sufficient to adjust the overall lift of the wind turbine blade; anda con...
