The transport properties of an $\text{N}_2$–$\text{H}_2$ mixture of rarefied gases in the EPIDIF database

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 $\text{N}_2$–$\text{H}_2$ mixture of rarefied gases is performed. Nine parameters of three $m$–$6$ Lennard-Jones potentials of interaction of $\text{N}_2$ and $\text{H}_2$ 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.
