PREDICTING THE BEHAVIOR OF ELECTRICAL EXPLOSION OF WIRE FOR NANO-POWDER PRODUCTION

摘要：

Electrical explosion of wire in embedded-gas is a new technique 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 exploding wire load. In the model, the entire process of wire explosion is subdivided into five stages: solid heating, melting, liquid heating, evaporation, and plasma growth. Voltage waveform, current waveform and deposition energy on the wire can be numerically simulated by the model. The measured voltage and current waveforms are in good agreement with the calculated results.
