CALCULATION OF TRANSPORT PROPERTIES MIXTURES OF HELIUM AND PARTLY-IONIZED ARGON

摘要

Transport properties have been calculated for equilibrium mixtures of helium and partly-ionized argon as functions of temper¬ature and helium concentration. Viscosity, thermal conductivity diffusion, and thermal diffusion data, as well as effective diffusion and thermal diffusion coefficients, are presented for temperatures up +o 15,000 °K helium concentrations from zero to 100％.nThe method was based on Chapman-Enskog theory, using collislonal data from various sources for the different particle inter¬actions. An alternate method based on a relaxation-time model was also used for viscosity calculations, and provided good correlation with the Chapman-Enskog results.
