چکیده
|
An experimental study of stationary and non-stationary dielectric barrier discharge (dbd) plasma actuator ispresented to control the flow around a naca0024 airfoil. first, an induced air velocity of ~5 m/s is generatedon a flat plate in still air using an ac-dbd actuator to find the optimal setup of the actuator (voltage,frequency, electrode width and gap size). using the same actuator in the optimal position/setup on anaca0024 airfoil at reynolds number of 0.48×10^6, we are able to increase the stall angle of the airfoil to18°, compared to 16° in no-actuator state. furthermore, during the plasma actuation, the lift is increased by upto 5%. we show that non-stationary actuation, while yielding a performance similar to stationary actuation,leads to a considerable reduction of ~51% in plasma power consumption.
