Accounting for resistance and temperature in a flow of a vapor-helium mixture through a layer of a porous composite sorbent based on microspheres

Research output: Contribution to journalArticlepeer-review

Abstract

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