Validation Test Cases for Multi-Physic Problems: Application to Magneto-Hydrodynamic Numerical Simulations

Abstract

In the present paper, some elementary test cases in laminar flow with magnetic forcing terms are analyzed (Hartmann flow, Couette flow, Rayleigh flow); equations of the coupled problem are exposed and analytical solutions are derived in each case, highlighting the relevant non-dimensional number which drives the physics of the problem. Several analytical calculations are then proposed and discussed, in particular in the context of MHD propulsion by a nozzle.Comment: 10
