The energy deposition process of electrical wire explosion under vacuum or low gas pressure circumstances is usually terminated prematurely due to the flashover along the surface of wires; therefore energy deposited into wires can be far less than the amount needed to fully vaporize them. In this paper, a parallel wire is introduced in order to improve the energy deposition of the concerned wire before...
Wire explosion is the initial stage of the development of wire array Z-pinch load driven by high pulsed current. Based on the pulsed power generator PPG-1 (400 kA/100 ns), the process of 10-\(\mu \) m-W wire explosion at tens of kiloamperes was investigated. The time sequence images of wire explosion were obtained by X-ray backlighting with X-pinch X-ray point source, and the mass density distribution...
Pulsed wire discharge in embedded-gas is a simple and efficient method for producing nanosize powder of metal, alloy, or metal compound. The powder size and size distribution are strongly related to the deposition energy into the wire load by joule heating. This paper established a numerical model to analyze and predict the behavior of electrical circuits containing pulsed current source and exploding...
