CALCULATION OF THE TRANSPORT PROPERTIES OF GASEOUS MIXTURES OF CF4 WITH O2, N2, CH4 AND CO2 AT LOW DENSITY USING SEMI-EMPIRICAL INVERSION METHOD

Abstract

Viscosity and diffusion coefficients for four equimolar binary gaseous mixtures of CF 4 with O 2, N 2, CH 4 and CO 2 are determined from the extended principle of corresponding states by the inversion technique. The Lennard–Jones 12-6 (LJ 12-6) potential energy function is used as the initial model potential required by the technique. The interaction potential energies from the inversion procedure reproduce viscosity within 1% and diffusion coefficients within 5%.
