Calculation of transport coefficients of a xenon plasma

Abstract

The viscosities, thermal conductivities and electrical conductivities of xenon plasma are obtained using Chapman-Enskog method expanded up to a higher approximation in a computation range from 300 to 40000 K under different pressures. In the local thermodynamic equilibrium regime, the results are compared with published experimental and computational results, showing that they are in good agreement with each other, which validates the accuracy of the computational method. The transport properties of xenon plasma are further obtained under the chemical equilibrium and thermal nonequilibrium, in which the electron temperature Te is different from that of heavy species Th. The evolutions of the transport properties with pressure and thermal nonequilibrium parameters (θ=Te/Th) are presented and analyzed.
