Abstract

This paper describes the application of a new scheme, that was developed for the solution of the MHD equations, to simulate magnetoplasma-dynamic thruster (MPDT) flows. In this scheme, the entire set of flow and field equations are solved in a self-consistent conservation form, using accurate characteristics-splitting techniques which have been proven to be effective in computational fluid dynamics. Further improvements to the physical model, such as the inclusion of real equation of state, anomalous transport and multi-temperature effects, are essential for the realistic simulation magnetoplasmadynamic flows, and are implemented without affecting the underlying scheme. The solver, including the improved physical model, is then used to simulate plasma flow in a real MPDT configuration. The results of the simulation were found to to be in general agreement with experimental observations. They illustrate the need for using a real equation of state, instead of the ideal one, to enhance the realism and stability of the simulation.
