Fully coupled Maxwell/Navier-Stokes simulation of electromagnetic hypersonics including accurate transport models

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. Copyright © 2009 by D. DAmbrosio, D.
