An Exploding-Wire Circuit Model

Abstract

A circuit model was developed to aid in predicting the outcome of exploding-wire experiments and to analyze the results of such experiments. The model tracks the internal energy of the wire over time and uses that to determine the temperature and resistance of the wire at each time step based on published heat capacity and resistivity values. A constant wire geometry is assumed. Individual models for pure magnesium, aluminum, titanium, copper, molybdenum, and tungsten wires were developed.
