Numerical Computation in MagnetoFluid Dynamics

Abstract

During the years supported by the subject AFOSR grant the following research accomplishments were made. Inclusion of both thermal and chemical non-equilibrium into the MFD equations. Simulation of the flow within MFD generators and accelerators for the proposed energy "bypass scram jet engine" concept. Reformulating the governing MFD equations for strong imposed magnetic fields, of the order of 10 Tesla, using the properties of the imposed magnetic fields, V. 13=0 and VxB=0, to avoid products of the order of 132 fiom dwarfing values of static fluid pressure. Analysis of the physics of upstream influence caused by magnetic difflision and the eigenvalue properties of the MFD equations in comparison with the simpler "low magnetic Reynolds Number" approach for flows within MED generators and accelerators. Analysis of non-uniqueness of the equations of magneto-fluid dynamics Inclusion of Cesium seeding into the flow and the Park model for calculating electrical conductivity based upon electron and ion concentrations. Analysis of the physics of upstream influence of the flow about the nose of a hypersonic vehicle.
