Abstract

Within the framework of multiphase media mechanics, a mathematical model of gas mixture dynamics is obtained, including helium and water vapor, in a layer of resting composite sorbent based on microspheres and a porous matrix of moisture absorber made of aluminum oxide. The study is carried out with account for the law of conservation of momentum with account for the force of resistance to the layer, described by the Forchheimer filtration relations, and the law of conservation of energy within the framework of a single-temperature non-heat-conducting models.
