Abstract :
A plasma actuator operating in atmospheric air was applied to attenuate low-speed cavity flow-induced tones. It demonstrated the working effect of glow discharges for aeroacoustic applications. The details of the overall system were summarized. To improve the power efficiency, several plasma driving signals were tested on a real-time system. The corresponding results were discussed in this paper.
