Abstract
The Chapman—Enskog method is used to obtain estimates for the coefficients of diffusion, thermal diffusion, and thermal conductivity for a dilute gas composed of two species of loaded‐sphere molecules. Calculations are presented for the case in which the load eccentricity of one of the species is vanishingly small and the mass and size of both species are identical. The results of these calculations are in agreement with the observed thermal‐diffusive behavior of the D2—HT system.
