Abstract

Within the framework of a unified methodical treatment a critical analysis is given of different methods for the phenomenological description of the processes of the gas permeability of heterogeneous media: lamellar, dispersion type, containing individual inclusions, etc. The introduction of a continuous geometrical factor allows generalised expressions for the effective transport parameters to be obtained. Mathematical modelling methods are used to check the adequacy of the mathematical apparatus considered. The prospects for a directed choice of the structure of the material for controlling the efficiency and selectivity of a gas-separating membrane are investigated.
