Abstract
In this study, intermittent control of the coaxial type DBD plasma actuator which generates an induction flow in a jet and the direction of the coaxial is performed. We performed simulate for research to diffuse gaseous mixture of fuel and air, it is that we attempted to intermittent control by plasma actuator using the carbon dioxide with the same molecular weight as propane. When duty was controlled by synthesizer, the influence on the main jet was investigated. As a result, two changes were seen by comparing the intermittent control on and off. One is that the potential area of the jet collapsed as a whole. Another is that the center velocity of the jet flow is decelerated by the Nozzle wall velocity is accelerated.
