Improvement of Aerodynamic Characteristics by a Plasma Actuator Installed in Transportation Equipment

－Consideration of Flow Velocity Region Suitable for Detachment Suppression－

Abstract

　　　It is known that DBD (Dielectric Barrier Discharge) plasma actuator is a promising technology on active control of the flow separation. Installing the actuator in transportation equipment aids energy saving running. The purpose of this study is revealed that the shape of plasma actuator and the installation site for optimizing aerodynamic characteristics by using a CFD (Computational Fluid Dynamics) analysis and a wind tunnel experiment.
