Hydraulic and gas-dynamic models of a steam-water mixture flow in a granular bed

Tairov E.A., Khan P.V. Hydraulic and gas-dynamic models of a steam-water mixture flow in a granular bed // Journal of Physics: Conference Series. Vol.1382. No.1. ID: 012101. 2019. DOI: 10.1088/1742-6596/1382/1/012101 The paper presents a comparative analysis of the hydraulic and gas-dynamic models of a steam-water mixture flow through a granular bed. The analysis is carried out using experimental data obtained at an inlet pressure of 0.6 - 15.5 MPa, flow quality of 0.002 - 0.3, and mass velocity...

A polytropic model of a critical two-phase flow in a bed of spherical particles

... Similarly to the known problem of gas dynamics of a granular bed we obtained the relationships for calculation of a critical mass velocity. The results of the calculation based on a theoretical model are compared with the experimental data obtained in the packed beds of steel balls, 2 mm and 4 mm in diameter. © 2017 The Authors, published by EDP Sciences. нет
