Plasma based active flow control using dielectric barrier discharge plasma actuators was investigated to reattach the simulated separation flow on suction surface of turbine blade at low Reynolds numbers, Re = 1.7 x 10^4 and Re - 3.1 x 10^4. The flow separation was induced on a curved plate installed in the test-section of a low-speed wind tunnel. Particle image velocimetry (PIV) was used to obtain two-dimensional velocity field measurements. The amplitude of input voltage for plasma actuator was changed from ±2.0 kV to ±2.8 kV. Large flow separation was moved closer to the curved plate by the flow control of the plasma actuator. This paper deals with the electrical and mechanical power characterization of plasma actuators.
