Abstract

Based on the underwater pulsed discharge platform, the effect of the electrical breakdown discharge modes on the shock wave intensity in water is discussed in the pin-to-plate configuration. Based on the analysis of discharge images captured by a high-speed camera, it can be concluded that the discharge modes are classified as subsonic bush-like streamers or supersonic filamentary streamers. Experimental results demonstrate that the amplitude of applied voltage have a great influence on the discharge modes as well as the shock wave intensity. In the experimental conditions a threshold value of 22.5kV is necessary for the subsonic streamers turning into supersonic streamers, which is a remarkable measure to reduce the energy loss and improve the energy conversion efficiency and eventually enhances the shock wave intensity.
