Control of Subsonic Flows with High Voltage Discharges
In this paper, a DC surface corona discharge established on a rounded edge of a dielectric material was studied in atmospheric air. The flow induced by this actuator was measured and experiments on a NACA 0015 were performed in a subsonic wind tunnel. These measurements showed that this discharge modified the fully detached flow on the airfoil up to Re=267 000 and 17.5° of angle of attack.
