Active Circulation Control (ACC) of aerodynamic structures (10), 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 (34) disposed in a surface (12, 14) of the blade at a location proximate to a trailing edge (22), a leading edge (20), or both the trailing edge and the leading edge of the blade. An active flow control device (32) in fluid communication with the opening (34) 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. |
