Abstract

Plasma actuator has been remarked for active flow control devices that do not contain mechanical moving parts. However, since velocity of induced flow is slow, performance of the plasma actuator was investigated experimentally for variety of parameters including alternating high voltage wave form, electrode thickness and dielectric plate material. The aim of this study is to investigate how design parameter affects the performance improvement of the actuator. Three types of electrode, Line [Span Type], Slot [Stream Type] and Porous [Porous Type], was tested and velocity of induced flow was measured by PIV system. Especially, Span Type electrode showed the best performance at fixed condition.
