ABSTRACT

Kinetic effects related to flows of gases and gas mixtures in capillaries and porous bodies are discussed. The models of porous media and the methods for calculation of kinetic coefficients are described. Much attention has been paid to the dusty-gas model. Results of calculation of the kinetic coefficients for small and large values of the Knudsen number are presented with due account for incomplete accommodation of molecules on the surfaces of capillary walls. Special features of gas flows in ultra-fine channels and the effects related to the action of surface forces, surface diffusion, entrainment of gases by phonons and quasi-one-dimensionality of gas flows have been considered. The effects of the asymmetry of gas transport through multilayer membranes have been discussed.
