An Implicit, Conservative Multi-Temperature MHD Algorithm
Abstract
A algorithm to accurately simulate plasmas with constituent species at multiple temperatures using the MHD model was developed. The algorithm was based on a Roe-type approximate Riemann solver. The algorithm was implemented in a code to model the time-dependent, three-dimensional, arbitrary-geometry MHD model which includes viscous and resistive effects. A time-dependent ionization model was added which self-consistently calculates the ionization fraction of the fluid. Energy loss mechanisms were added for the constituent fluid components (neutrals, ions, and electrons). The algorithm was implemented on parallel supercomputers to allow the detailed modeling of realistic plasmas in complex three-dimensional geometries.
