Abstract

A 2-D resistive MHD (magnetohydrodynamic) code is used to simulate an EML plasma armature. The energy equation includes ohmic heating, radiation heat transport, and the ideal gas equation of state, allowing for variable ionization using the Saha equations. Rail ablation is calculated, taking into account the flow of heat into the interior of the rails. Simulations show the development of internal convective flows and secondary arcs. An explicit flux corrected transport algorithm is used to advance all quantities in time
