โœฆ Synopsis


The relations between diffusion fluxes and the distribution function moments at the channel walls have been established for a multicomponent gas mixture flowing in a plane channel. The problems of barodiffusion and thermal diffusion in the binary mixture are discussed.

Different forms of expressing diffusion and heat fluxes in multicomponent mixtures, obtained by methods of non-equilibrium thermodynamics and the kinetic theory of gas mixtures, are analysed and compared. It is shown that an alternative representation of the linear relations of non-equilibrium therm
