Numerical modelling verification for re-entry vehicles using enhanced MHD simulation tools
Heat flux mitigation for spacecraft during re-entry is of fundamental importance for the success of a mission. In order to exploit magnetohydrodynamic (MHD) effects as protection system, numerical tools to predict the behaviour of atmospheric entry plasma flows in thermochemical non-equilibrium (TCNEQ) under the influence of externally applied magnetic fields have been developed. Two magnetic flow control experimental test cases with argon have been numerically rebuilt by means of the three MHD codes SAMSA, HANSA and COOLFluiD and the results of the simulations compared with each other and the experimental results. The codes are capable to detect the MHD-effects on the plasma, i.e. increase in shock standoff distance and decrease in heat flux. A sufficiently good agreement with the available experimental results has been found but some discrepancies for some flow parameters are present.

Abstract
Heat flux mitigation for spacecraft during re-entry is of fundamental importance for the success of a mission. In order to exploit magnetohydrodynamic (MHD) effects as protection system, numerical tools to predict the behaviour of atmospheric entry plasma flows in thermochemical non-equilibrium (TCNEQ) under the influence of externally applied magnetic fields have been developed. Two magnetic flow control experimental test cases with argon have been numerically rebuilt by means of the three MHD codes SAMSA, HANSA and COOLFluiD and the results of the simulations compared with each other and the experimental results. The codes are capable to detect the MHD-effects on the plasma, i.e. increase in shock standoff distance and decrease in heat flux. A sufficiently good agreement with the available experimental results has been found but some discrepancies for some flow parameters are present.
