Outline of Final Research Achievements

Pulsed-driven plasma actuator has been developed for active flow control. A plasma actuator is usually driven by alternative current power source, however, we used the pulse voltage power source to improve the availability of the plasma actuator in high speed flow condition. Wind tunnel experiments were conducted at various angles of attack and non-dimensional pulse frequencies. Force and surface pressure of the airfoil were measured to evaluate the availability of the plasma actuator. As a results, we successfully demonstrated the the availability of pulsed-driven plasma actuator in 15-40 m/s flow condition with using NACA0015 airfoil model whose span is 300 mm and chord is 100 mm.
