System And Method Of Operating An Active Flow Control System To Manipulate A Boundary Layer Across A Rotor Blade Of A Wind Turbine

Abstract: An active flow control system for manipulating a boundary layer (56) of air across a wind turbine rotor blade (28), the wind turbine rotor blade having at least one sidewall (62) defining a cavity (68) therein, the sidewall extending between a leading edge (74) and an axially spaced trailing edge (76) is provided. The active flow control system includes an air discharge assembly (88) coupled to the sidewall, the air discharge assembly configured to selectively discharge air from within the wind turbine rotor blade into the boundary layer, and an air suction assembly (86) coupled to the sidewall and to the air discharge assembly, the air suction assembly configured to channel air from the boundary layer to the air discharge assembly.
