Abstract

In order to study the difference in energy conversion efficiency of the shockwaves induced by the expansion of the plasma channel generated by underwater metal wire explosion (MWE) and subsonic streamer breakdown discharge (SSBD), a test stand was constructed, and the experimental results were obtained based on the condition that the voltages of the two discharge modes were the same at the time of the formation of plasma channels. The results showed that the peak value of shockwaves induced by the expansion of the channel and the energy conversion efficiency of MWE were much higher than those of SSBD. The reason lies in the difference in the injected power at the formation moment of the plasma channel and the difference in the time distribution of energy deposited into channels.
