플라즈마 액츄에이터를 이용한 사각공동에서의 유동 제어

The object of this study is understanding flow characteristics on rectangular cavity and probe the flow controlling method which using dielectric barrier discharge plasma(DBD plasma) actuator. Plasma actuators are set up in front of rectangular cavity at different directions. Measure the changes of flow field after operate each plasma actuators by utilizing particle image velocimetry(PIV). Aspect ratio of rectangular cavity and direction of flow acceleration make different phenomena and according to these results, flow controlling method by DBD plasma is verified.
