Dielectric barrier discharge (DBD) plasma actuators have been investigated by many researchers as flow-control devices. In the present study, we attempt to apply such actuators to a jet flow. In order to achieve enhanced mixing in a jet flow, we focused on the voltage and the frequency of the plasma actuator to examine their effect on the velocity and turbulence of the jet flow. This time, we examined how the induced flow by the plasma actuator electrode dimensions occurred. It was expected that higher velocity would have a larger effect on the jet flow in last year. In this study, we measured the flow velocity for different voltages and frequencies, and determined the most effective conditions for generating the induced flow. We apply that DBD plasma actuators to enhance turbulent intensity and jet flow’s diffusion.
