NUMERICAL SIMULATION OF HIGH-TEMPERATURE REACTING FLOW IN PRESENCE OF AN APPLIED MAGNETIC FIELD USING ACCURATE PHYSICAL MODELS

摘要

A Navier-Stokes solver for non-equilibrium aerothermodynamics is coupled with a fully implicit solver of the Maxwell equations. Transport phenomena are modelled using a high accurate Chapman- Enskog method that accounts for the effects of concentration, pressure and temperature gradients and provides anisotropic diffusion velocity, heat flux and viscosity in the presence of a magnetic field. Gas neutrality is not enforced so that the electric charge density can be locally different from zero. Numerical tests are carried out on a flat-faced cylinder to test the capabilities of the implicit Maxwell solver and of the coupled Maxwell/Navier-Stokes system.
