Abstract

A new multi-temperature code for a multi-component gas-dynamic is tested. The velocities of all components with nonzero mass are assumed to be identical to each other. The method operates with the tabular equation of state. The method may take into account the electron heat conduction, the radiation transfer, the exchange of energy between components, and the chemical reactions. The gas-dynamic part is based on the Godunov approach with the efficient approximate solution of the Riemann problem solver and the application of the local equation of state. The goal of the investigation is to verify the code and obtain an exact solution of Shafranov’s task for a shock wave in hydrogen plasma.

Keywords:

multi-temperature plasma equation of state Godunov-type scheme
