Influence of Different Wire Diameter and Discharge Period on Copper Wire Electrical Explosion

Wire electrical explosion has important applications in the fields of Z-pinch, nano powder preparation and special processing. In this paper, the electrical explosion process of copper wire in vacuum was studied by numerical simulation, and the effects of wire diameter and discharge period on the electrical explosion process of copper wire were investigated. The simulation results show that the use of fine wire has higher energy efficiency than that of thick wire. In addition, the effect of electric explosion of filament is hardly affected by the speed of discharge. When the wire diameter increases, the faster the discharge, the worse the spatial uniformity of electric explosion, but on the other hand, it can also improve the energy utilization efficiency of electric explosion.
