Experimental comparison of atmopsheric pressure plasma actuator geometries

Summary form only given. In this study we examine two configurations for the asymmetric surface barrier plasma actuator. This discharge is designed to generate air flow near its surface, and has been shown, when placed on a surface, to increase the angle of attack at which flow separation occurs. Such a device could be used as a "virtual flap" by controlling flow over an airplane wing. The configurations studied include systems with one exposed electrode above the dielectric surface and one sealed electrode below and two encapsulated electrodes below the surface. We present data describing the light emission, current-voltage characteristics, and induced air flow of each discharge
