... transferred to the condensed state, and the released space is filled with the measured amount of additional fluid. The result of verification using this method is presented for the previously proposed formula for calculating the void fraction of the adiabatic steam-water flow in a channel with a fixed bed of spherical particles. © 2020, E.A.

Modeling the mass velocity and pressure drop of forced vapor-liquid flow through a granular bed // International Journal of Multiphase Flow. 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...
