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

摘要

An Enskog-Landau kinetic equation for a many-component system of charged hardspheres is proposed. It has been obtained from the Liouville equation withmodified boundary conditions by the method of nonequilibrium statisticaloperator. On the basis of this equation the normal solutions and transportcoefficients such as bulk kappa and shear eta viscosities, thermal conductivitylambda, mutual diffusion D^{\alpha\beta} and thermal diffusion D_T^\alpha havebeen obtained for a binary mixture in the first approximation using theChapman-Enskog method. Numerical calculations of all transport coefficients formixtures Ar-Kr, Ar-Xe, Kr-Xe with different concentrations of compounds havebeen evaluated for the cases of absence and presence of long-range Coulombinteractions. The results are compared with those obtained from other theoriesand experiment.
