摘要

The microhydrodynamic approach previously proposed for calculating the transfer of a single-component fluid with an arbitrary density in the vicinity of solid surfaces in porous materials and/or in a flow around open solid bodies was generalized to multicomponent mixtures of spherical molecules comparable in size. The lattice-gas model was used to construct a theory according to which the equations derived for a liquid phase can be extrapolated to a gaseous phase. It was demonstrated that the equations for pair distribution functions must be retained to take into account the molecular properties of the dissipative coefficients. It was noted that the proposed variant of the theory can be successfully used to overcome the problems of the rigorous kinetic theory, which is applied to gases differently than to liquids. The procedure used for refining the inclusion of the intermolecular interactions under dynamic conditions in the calculation of the dissipative coefficients was discussed.
