Abstract

Gas flow has been considered in a porous membrane with nanosized channels, for which the influence of surface forces and relevant effects must be taken into account. The problem of entropy production in such systems has been discussed. It has been shown that, when calculating the total entropy production in such a system, it is necessary to take into account the entropy production at the inlets and outlets of the channels of the porous body. The entropy production has been determined, and the phenomenological equations describing the heat and mass transfer through the porous body-gas interface have been found.
