Development of a Micro Plasma Actuator Array for Near-Wall Body-Force Generation

Abstract

In order to apply plasma actuator to boundary layer transition control, it is necessary to introduce a body force into the appropriate part of the boundary layer, especially near the wall surface. To develop a device that can introduce body force only near the wall surface, we fabricated micro plasma actuators arrays using photolithography, and investigated the generated body force and jet characteristics. Velocity distribution measurements using a hot-wire anemometer were used to analyze the jet characteristics, and the body force distribution of the conventional and micro plasma actuators was clarified.
