TRANSFER PROPERTIES OF MIXTURES OF RAREFIED NEUTRAL GASES. HYDROGEN-ARGON SYSTEM

摘要

A method is proposed for generalization of the transport properties of mixtures of rarefied gases on the basis of their particle-interaction potentials and relations of the molecular-kinetic theory. A simultaneous processing of data on the viscosity of a binary Ar-H_2 mixture and its components as well as data on the concentration-diffusion and thermal-diffusion coefficients of this mixture has been carried out by the weight method. The parameters of three functions of the Lennard-Jones (m-6) potential of interaction between the Ar atoms and H_2 molecules in the indicated mixture were determined. Tables of reference data on the transport properties of the Ar-H_2 mixture at a temperature of 200-2000 K and a concentration x(Ar) varying from 0 to 1 were calculated.
