Abstract: A turbine blade for a wind turbine, the turbine blade has a blowing and suction provision in form of a plurality of arrays of blowing and suction holes defined on a curved suction surface of the turbine blade. An apparatus for turbine blade testing includes the turbine blade. The apparatus also includes a wind tunnel, a blowing source, and a suction source. The wind tunnel includes a wind channel having first and second end plates for mounting the turbine blade. A method of testing air flow in a turbine blade involves changing holes used for blowing and suction and determining a momentum coefficient for those various holes; and varying angle of attack with measurement of lift/drag ratio.
