Study and Design of a Plasma Reactor Using a Porous Dielectric Barrier

Abstract

To continuously improve actuator performance, it is necessary to study the discharge to better understand its operation. Therefore, this work focuses primarily on the ion wind and its stability. In other words, the goal is to obtain the maximum possible ion wind without generating arcs. To increase the ion wind speed, it is necessary to increase the discharge current (recall that the ion wind speed is proportional to the square root of the discharge current i) (5), thus increasing the potential without reaching the breakdown voltage in air. It is therefore important to observe the behavior of the ion wind for several discharge configurations and to find the optimal configuration suitable for flow control. The main parameters essential to study are: the electrode diameter, the inter-electrode distance, and the nature of the dielectric on which the discharge occurs.
