AbstractThe effects of a DBD plasma actuator applied to a NACA0012 airfoil were examined at a Reynolds number of 10,000 using three approaches, namely, aerodynamic force measurements using a wind tunnel balance, velocity profiles of the wake obtained using a hot-wire anemometer, and smoke-wire visualization around the airfoil. As a result, the magnitude of lift approximately doubled and the drag was reduced by about 30 percents. The lift curve changed from nonlinear to linear at the lower angles of attack below 6 degrees with actuator operation. These phenomena are occurred by suppression of flow separation near the leading edge. This separation was suppressed by a downwash induced by the actuator operation. Though there might be some limitation in the performance of the plasma actuator against the angle of attack, the plasma actuator enhanced the aerodynamic performance of the airfoil under our experimental conditions.
