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. Up to now, to promote the diffusion of the jet flow, we had examined the influence that the generation flow exerted on the jet flow by continuously generating plasma. This time, we examined what influence the generation flow exerted on the jet flow by giving plasma an intermittent control. In the actual experiment, we examined what influence the generation flow exerted by controlling intermittent by using coaxial type DBD plasma actuator set up at the nozzle exit, and changing the value of intermittent ratio duty and intermittent frequency f_d in the early region of the jet flow. As a result, it was able to be confirmed that a center speed decelerated by controlling intermittent in the early region of the jet flow.
