Abstract

The paper features the mathematical model of computing nonequilibrium thermophysical properties of state in the fluid domain for hydrofluorocarbon mixture with the help of statistical nonequilibrium mechanics. In the presented paper we calculated viscosity for mixtures HFC-134a (1,1,1,2Tetrafluoroethane) and HFC-125 (Pentafluoroethane) as the example of hydrofluorocarbon mictures. To calculate the thermodynamic properties of real fluid the models on the basis of Lennard-Jones intermolecular potential were applied. The analytical results obtained by statistical mechanics are compared with the experimental data and show relatively good agreement.
