Direct statistical simulation of gas mixture mass transfer in a porous layer with condensation of one of the components and absorption of another

Abstract

Based on the method of direct statistical simulation, a physical–mathematical model has been developed for gas mixture mass transfer in a highly porous body under the conditions of condensation of one of the components and trapping of a non-condensable admixture. Distributions of gas velocities and densities in a porous layer and in the space above it are found, as well as distributions of flows of a condensable component and absorbable admixture along the depth of the porous layer. The efficiencies of the absorption of the admixture in a porous layer and on a plane surface are compared.
