Abstract : Transport properties were calculated for equilibrium mixtures of helium and partly-ionized argon as functions of temperature and helium concentration. Viscosity, thermal conductivity diffusion, and thermal diffusin data, as well as effective diffusion and thermal diffusion coefficients, are presented for temperatures up to 15,000 K and helium concentrations from zero to 100%. The method was based on Chapman-Enskog theory, using collisional data from various sources for the different particle interactions. An alternate method based on a relaxation-time model was also used for viscosity calculations, and provided good correlation with the ChapmanEnskog results. (Author)
