液体中金属丝电爆炸的研究现状与展望

Different from electric breakdown of liquids, exploding metal wires involves a series of complex phase transition processes, resulting in shock waves with higher energy transfer efficiency. The shock wave source based on wire explosions has been successfully applied in reservoir exploitation, and it also shows emerging prospects in geological exploration, mine and safety engineering, etc. This paper reviews the development and current research situation of wire explosion in liquids. The physics of phase transition, as well as the generation, diagnostics, influencing factors of the shock waves are presented. Meanwhile, the related applications in reservoir stimulation, basic physics, nano-material preparation, etc are introduced in detail. The key points and difficulties in future research are put forward in the aspects of fundamental research and industrial applications. Finally, a roadmap for the technology of exploding metal wires in liquids is summarized and proposed.
