Abstract
This paper presents a novel actuator for flow control, namely Plasma Actuator. This is a glow-discharge actuator, which is composed of the electrodes with AC signal. In the present study, it was applied to the separation control of airfoil. Actuator. The NACA0012 airfoil, in which this actuator was embedded, was set in the wind tunnel. The wake velocity behind airfoil was measured with or without operating the actuator. Consequently, the expected effect of proposed actuator could not be observed. One of the reason was thought to be a large separation bubble causing under low Reynolds number condition. The actuator would be completely involved in this, and thus was no seen to be effective to the separation control.
