Semi-Emperical Calculation of the Transport Properties of Eight Binary Gas Mixtures at Low Density by the Inversion Method

Abstract

Abstract Viscosities, diffusion coefficients, and thermal-diffusion factors for eight equimolar binary gas mixtures (Ne+O2, Ne+CO2, Ne+N2O, Ne+SF6, Ar+O2, Ar+CO2, Ar+N2O, and Ar+SF6) were determined based on the principle of the corresponding states of viscosity using the inversion technique. The Lennard-Jones 12-6 potential energy function was used as the initial model potential required by the technique. Typically, the interaction potential of Ar+SF6 has been compared with those obtained from thermal-diffusion measurements. Our inverted potentials are in excellent agreement with it. The interaction potential energies from the inversion procedure reproduce the viscosities to within 1%, the diffusion coefficients to within 5%, and the thermal-diffusion factors to within 25%.
