Akin'shyn V. Gas Dynamics of non-equilibrium systems "Rarefied gas - nuclear membrane"

The contribution of rarified gas molecules interaction with solid surface to microscopic characteristics of gas flow along of different shape and size channels has been investigated. The interaction between physic-chemical characteristics of interphase border and the character of transfer phenomena in unequilibrum gas - solid system has been determined. Thermodynamic analysis of the gas molecules transfer in membrane channels, with thermo penetrability of their sides as well as phase interaction in indivisible gas-adsorbat-membrane system considered, has been carried out. The corresponding kinetic coefficient moulds have been obtained. Different contributions to the transfer elements with some local equilibrium in a channel length element available are analyzed. New analytical and numeral data on kinetic coefficient have been obtained via the statistic modeling of rarified gases and their mixtures movement in channels. The evaluation of gas movement kinetic coefficients in ultra thin channels, with amolecule size diameter has been provided. Quantum-kinetic approach to gas diffusion by the surface for description of impulse transfer and energy in unequilibrum gas-solid system with an adsorbat has been applied.
