Abstract :
A model for the analysis of the magneto-plasmadynamic regime, devoted to 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 discretised by means of a finite volume formulation. The electrodynamics is discretised by means of a finite element method. The model has been utilised 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.
