... approaches frequently used to model pressure drop in a granular layer. These are a model of a hydraulic circuit element, a Lockcart–Martinelli model, and a generalization of the Darcy–Forchheimer model. A new model, representing a generalization of the gas dynamics equations to a two-phase flow, is proposed. The results of the considered models verification by two groups of experimental data obtained at different facilities are presented. The experiments employed granular beds with a height of 50 mm,...
