摘要：
Surface dielectric barrier discharge (SDBD) actuator is widely used in plasma flow control. The surface ionization wave (SIW) propagation is one of the important parameters for optimizing the control effect of the actuator. In this paper, using PTFE and epoxy resin (ER) as dielectric materials, surface dielectric barrier discharge actuator with multi-GND electrode array structure was fabricated. The propagation characteristics of surface ionization wave in the surface dielectric barrier discharge were studied experimentally using nanosecond high voltage pulse power supply. The experimental results show that at the rising edge of the pulse voltage, two breakdowns occur, forming a discharge channel, namely the primary ionization wave and the secondary ionization respectively. There are two peaks on the current curve, the first peak indicates the primary ionization wave, and the second peak indicates the secondly ionization wave. The charge distribution and evolution are obtained by integrating the current curves at different positions. It is found that the charge electrode dissipates faster near the high voltage, while electrode dissipates more slowly when the charge far away from the high voltage. Moreover, the charge residual of PTFE medium is obvious after discharge, but that of ER medium is not obvious. In addition, the effects of applied voltage amplitude and repetition frequency on SIW propagation characteristics were studied. With a constant voltage amplitude (14kV), the repetition frequency has little influence on the propagation speed of SIW in the range of 100~1 000Hz, but the decay speed of SIW is faster with the increase of the repetition. With a constant repetition frequency (500Hz), when the voltage amplitude changes from 8kV to 17kV, it is found that the voltage amplitude has little influence on the decay of SIW, but the propagation speed of SIW increases with the increase of the voltage amplitude. The results are helpful to the optimize the discharge parameters of SDBD actuator. © 2020, Electrical Technology Press Co. Ltd. All right reserved.
