Calculation of Transport Coefficients for CH₄–N₂ and CH₄–O₂ by the Inversion Method

Abstract

Viscosities, diffusion coefficients and thermal diffusion factors for CH₄–N₂ and CH₄–O₂ are determined from the extended law of corresponding states for viscosity and the experimental second virial coefficient data by an iterative inversion method. The Lennard-Jones (12,6) potential energy function is used as the initial model potential required the technique. The obtained effective interaction potentials reproduce viscosity, diffusion and thermal diffusion factor within experimental accuracies.
