Abstract

In this paper, we propose a mathematical model to describe the dynamics of a mixture of gases, including helium and water vapor, in a layer of a resting composite sorbent based on microspheres and a porous matrix of an aluminum oxide moisture absorber using the multiphase media mechanics approach. We show how to match the flow in a porous adsorber medium and the diffusion of gases in a cylindrical adsorbent granule, taking into account the adsorption of helium by microspheres and water vapor by the porous surface of the adsorbent.
