Abstract
By coupling Poisson's equation for the electric potential field with flow-field N-S equations through Lorentz force and the joule heat, numerical simulation of magneto-fluid with low magnetic Reynolds number was carried out. The influence of the Hall effect and the external circuit was considered. The Poisson's equation ill-conditioned matrix caused by high Hall parameter was overcomed by LUSGS pretreatment BI-CGSTAB algorithm without pseudo time step. Numerical simulations of two kind of phenomenon, hypersonic magneto-fluid flow around a circular cylinder when Hall parameter reaching about 102 and the energy deposition in scramjet isolator, indicate that external circuit, electrode cooling measures and plasma uniformity have great influence on the electro-magnetic force.
