Abstract
A model for the analysis of the magneto- plasmadynamic regime, devoted to MHD systems in a hypersonic blunt body, 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 the MHD interaction in the boundary layer of a test body in a wind tunnel. The activity is aimed to the design of the experimental activity in the frame of an ASI research project on the MHD interaction in hypersonic flows. Calculations has shown that MHD interaction can be strongly weakened by the effect of the Hall current. © 2003 by the American Institute of Aeronautics and Astronautics, Inc.
