Abstract
A dielectric barrier discharge (DBD) plasma actuator has been investigated as a device for flow control by many laboratories. In this study, we try to use it for jet diffusion. In order to achieve mixing enhancement of jet flow, we focus on two parameters, voltage and frequency of plasma actuator, to examine how induced velocity and turbulence occur. This time ,We examined how the induced flow with the plasma actuator electrode dimensions occurred. It is because that we guessed the more induced flow speed, the more influence to the jet flow. Concretely saying, we measured the flow speed setting the voltage and the frequency. As a result, the most effective and safest condition to generate the induced flow was discovered.
