Effect of Electrode Arrangement on Body Force Generation in Plasma Actuators with Multiple Encapsulated Electrode

Abstract

The objective of this study is to numerically investigate the effect of multiple encapsulated electrode configurations on the body force generation in plasma actuator. As a result, the amount of body force generation and the efficiency are improved by providing gaps in the encapsulated electrode. It is considered that the change in the surface charge causes local enhancement of electric field and that leads to the enhancement of the body force generation.
