Full three-dimensional Navier-Stokes equations with low magnetic Reynolds number assumption on the basis of Favre weighted average mass are used to solve the complicated flow field of supersonic viscous channel flow including shock wave,boundary layer and the interaction between them by introducing finite volume stationary numerical method of implicit LU-SGS method combined with first-order OC spatial scheme,second-order Harten-TVD one respectively.Validation of the arithmetic are realized by numeric...
