Normal solution and transport coefficients to the Enskog–Landau kinetic equation for a two-component system of charged hard spheres: The Chapman–Enskog method

An Enskog–Landau kinetic equation for a many-component system of charged hard spheres is proposed. This equation is obtained from the Liouville equation with modified boundary conditions by the method of nonequilibrium statistical operator. On the basis of this equation the normal solution and transport coefficients such as bulk κ and shear η viscosities, thermal conductivity λ, mutual diffusion Dαβ and thermal diffusion DTα are obtained for a binary mixture in first approximation using the Chapman–Enskog method. Numerical calculations of κ,η,Dαβ and DTα for Ar–Kr, Ar–Xe, Kr–Xe mixtures with different concentrations of compounds have been evaluated for the cases of absence and presence of long-range Coulomb interactions. The results are compared with those obtained from other theories and experiment.
