Abstract :
Experimental and computational images of a 90-μm thick copper wire explosion in atmospheric pressure air are presented. A Marx generator is used to produce a pulsed current density into the wire with a maximum rate of rise of ~ 1018 Am-2 s-1. A multiphase numerical model includes mass and momentum conservation equations, thermofield ionization, Maxwell´s equations, and heat transfer between the phases. Visual records of the experiment agree with the simulation results.
