Abstract
Plasma actuator is up to date and innovative device for flow control. Plasma actuator can induce wall-jet flow by dielectric barrier discharge mechanism. Plasma actuator has many advantages (1) Light weight and simple structure, (2) No drive mechanism, (3) High jet velocity, and (4) Rapid response. Plasma actuator is effective in preventing flow separation in many fluid machinery and engineering devices by these features. We will introduce various applications for flow separation control.
