Numerical modeling of MHD interaction in the boundary layer of hypersonic flows

A model for the analysis of the magnetoplasmadynamic regime, devoted to magnetohydrodynamics (MHD) systems in a hypersonic flight vehicle, is presented. In the model, the discrete formulation of fluid dynamics and electrodynamics are coupled. The Navier-Stokes equations are discretized by means of a finite volume formulation. The electrodynamics is discretized by means of a finite-element method. The model has been utilized for the analysis of MHD interaction for the fluid control over a hypersonic body. Calculations have shown that MHD interaction can strongly affect the boundary layer fluid dynamic regime.
