The transport properties of an N2-H2 mixture of rarefied gases in the EPIDIF database

Abstract

The principles of organization of the EPIDIF information-and-computation database are considered. Simultaneous processing of experimental data on the viscosity of pure components and mixture and on the coefficients of interdiffusion and thermal diffusion for a binary N2-H2 mixture of rarefied gases is performed. Nine parameters of three m-6 Lennard-Jones potentials of interaction of N2 and H2 molecules are determined within the least squares method. Tables of reference data for the considered transport properties are calculated in the temperature range from 100 to 1500 K and concentration range of 0–1(0.2). The parameters and their error matrix are included in the EPIDIF database.
