Abstract

Abstract: A computational model is established to describe the physical process of exploding wires in a vacuum. The computational model is coupled with equation of state and transport coefficient model that can describe the phase transition of the wire from the solid state to the plasma state. The characteristics of exploding aluminum wires of different diameters are studied and compared with relevant experimental data.

Key words: Exploding wires, Magnetohydrodynamics, Equation of state
