摘要

Renewed interest in the calculation of transport coefficients stems from the need to have reliable data tornbe used for CFD modelling of high enthalpy flows of aerospace interest. The application of the MHDrninteraction concept, in particular, calls for a theoretical treatment that allows for the anisotropyrnintroduced by the presence of the magnetic field. Calculations have been performed for accuraterndetermination of transport coefficients of partially ionized Argon and Air in a magnetic field. Therncalculations employed the Chapman-Enskog method up to very high orders of approximation torncalculate the tensorial transport coefficients of the plasma. The study considers the general case ofrnionization nonequilibrium in a wide temperature range under the action of an imposed magnetic field.rnThe internal structure of the molecular species was considered in order to account for internal thermalrnconductivities. Representative results from this extensive set of calculations are reported and somernrecommendations for use in CFD modelling are drawn.
