Analytical Calculation of Diffusion Coefficients and Other Transport Properties in Binary Mixtures

Abstract

Nomenclature D12 = binary diffusion coefficient, m2/s Fc = secondand third-order correction factor of viscosity k = Boltzmann constant, J/K kt = thermal diffusion ratio M = molecular mass, kg/kmol N = number of molecules in system Rm = universal gas constant, J/kmol K T = temperature, K T ∗ = reduced temperature αt = thermal diffusion factor e = Lennard–Jones parameter, J η = dynamic viscosity, Pas σ = Lennard–Jones parameter, m ψi = molar fraction of component I = collision integral, m3/s ∗ = reduced collision integral
