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

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

The paper is concerned with a model of isenthalpic flow of vapor-water mixture in a fixed bed of solid particles. The mixture expansion process is considered to be polytropic. Similarly to the known problem of gas dynamics of a granular bed we obtained the relationships for calculation of a critical...
