Abstract

Abstract:

In a low speed jet wind tunnel, the transition point of a flat plate controlled by a single-stage dielectric barrier discharge (DBD) plasma actuator has been studied. Applying hot wire measurement technology, the transition location is judged by boundary layer velocity fluctuation and velocity profile. The flow speed of the experiments is 15m/s and the discharge parameters of the actuator are voltage peak to peak value is 11 kV, frequency is 4.7 kHz. After the analysis of the velocity fluctuation of the same height within boundary layer, the results show that the transition point is delayed about 40 mm farther downstream when the actuator is working. With the same flow speed and actuator distribution, actuators with different discharge parameters and their effects on the velocity profile, velocity fluctuation and amplitude spectrum of hot-wire signal within the boundary layer have been studied. It is discovered that higher discharge voltage,frequency and duty ratio can further delay the transition point. According to the experiment results, the jet generated by the plasma actuator strengthens the fluid stability of the boundary layer. As the discharge voltage, frequency and duty ratio goes up, the power of the jet gets stronger, which further strengthens the boundary layer stability and delays the transition location.

Key words: flat plate boundary layer, plasma actuator, transition, velocity fluctuation, hot wire
