TRANSPORT PROPERTIES OF POLAR GAS MIXTURES

Abstract

A previously proposed model for the calculation of viscosity, diffusion, and thermal diffusion in dilute polar gases is extended to mixtures. A simple set of combination rules for the potential parameters is postulated and discussed. Available data limit the comparison of calculation and experiment to binary mixtures of a polar and a nonpolar gas. The agreement exhibits a success comparable to that obtained for models and combination rules involving only nonpolar gases. It is concluded that the present model and combination rules can be used to describe the transport properties of mixtures with a fair measure of success. Attempts to refine the combination rules should await more experimental results of high accuracy, especially results on thermal diffusion and diffusion.
