The paper discusses the numerical analysis results of the aerodynamic structure of a flow in the granular adsorbent layer in a pressure swing adsorption unit adsorber during atmospheric air separation and oxygen concentration. The computational experiments were carried out using one-dimensional and two-dimensional mathematical models to calculate the velocity field in the adsorbent bulk layer. While assessing the accuracy of calculating the aerodynamic structure of the gas flow in the adsorbent, it was found that the use of a two-dimensional mathematical model provides an increase in the accuracy of calculations by an average of ~1-2% compared with the one-dimensional model.
