The Generalized Law of Filtration Darcy, as Inquest of Relations of Stefan-Maxwell for Heterogeneous Medium

A. V. Kolesnichenko, V. M. Maximov


Abstract: The methods of non-equilibrium thermodynamics receive relations Stefan-Maxwell for a heterogeneous medium and adjusted expression for a full flow of heat. On the basis of these relations of filtration movement of a multiphase mixture in a pore space of a rigid body (with capillary properties) are analysed, provided that the pressure in phases do not coincide, and the generalized law of a filtration Darcy, spreading the classic theory of two-phase flow on a common case, is received. The algebraic equations permitting to define factors of relative permeability of phases (for which one in the literature there are no systematic experimental data) through binary factors of interphase friction are offered.
