Body Force Production of a Micro Plasma Actuator Array

Abstract

In this study, our goal was to enhance boundary layer transition control through the use of plasma actuators. We developed a micro plasma actuator array via photolithography, designed to apply forces near the wall surface. Our analysis, conducted using Particle Image Velocimetry (PIV) measurements, revealed the generation of both positive and negative volumetric forces due to electrode interference, which led to a spreading of the jet flow. It became clear that this aspect needs to be addressed for further optimization. The comparison with conventional plasma actuators indicates a promising potential for the improved control of boundary layer transitions using our micro plasma actuator array, pending modifications to rectify the observed interference issue.
