Numerical simulation of Argon fuelled self-field magnetoplasmadynamic thrusters using the central-upwind scheme flux interpolations

In the present paper, we describe the implementation of a density-based scheme including a divergence cleaning method for the simulation of the magnetohydrodynamic (MHD) equations under a finite volume formulation. This new algorithm was developed for both ideal and resistive MHD equations and makes use of the central-upwind schemes of Kurganov and Tadmor for flux calculation. The developed density-based code is validated through comparisons of the obtained results with experimental data and simulations of previous works. The obtained results are in good agreement with the experimental data and previous simulation results.
