A diffusion stabilized central scheme to solve magneto plasma dynamic thruster equations is presented. The governing formulation in addition to the conventional fluid dynamics and electromagnetics description, accounts for terms such as hall current, static charge, conductivity etc.,. This causes inadequacy of regular schemes of MHD equations for a stable and accurate computation. In this context an efficient central scheme is devised by an eigen analysis of hyperbolic convective term. Spectral radius of the Jacobian is used to devise a Rusanov type scheme for obtaining the flux derivatives. Application of the scheme to single fluid plasma thruster yielded results in consistence with general physics of the problem as reported.
