This paper describes the formulation and the evaluation of a recently developed multigrid finite-difference calculation procedure for steady three-dimensional magnetohydrodynamic flows. This procedure solves in primitive variables the parabolized steady-state magnetohydrodynamic equation set which consists of the mass continuity equation, three momentum equations, the energy equation, the turbulence kinetic energy and dissipation rate equations, and Maxwell's equations using a full approximation storage block implicit multigrid finite-difference technique. This new technique is first validated by comparing predicted results with experimental data for a supersonic and a subsonic Faraday generator. The performance of this technique is then assessed in terms of computational speed and solution accuracy. 29 refs., 7 figs., 6 tabs.
