Tairov E.A. Method of measuring void fraction in a channel with porous media // Thermophysics and Aeromechanics. Vol.27. No.2. 2020. P.313-316. DOI: 10.1134/S0869864320020134 A new method is described for measuring the average void fraction of a one-component two-phase flow moving in a channel with a fixed porous aggregate. The known method of cutting off the flow is used but, in contrast, the vapor phase in the cut-off volume is transferred to the condensed state, and the released space is filled...

Vol.133. ID: 103466. 2020. DOI: 10.1016/j.ijmultiphaseflow.2020.103466 The paper considers the 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....
