Abstract

A theoretical study of the non-equilibrium phase transition in a steam-drop medium has been carried out. The previously proposed model has been refined, taking into account the influence of the vapor phase. Comparative numerical simulation of the superheated liquid outflow was performed on thermodynamic equilibrium and non-equilibrium relaxation models of the phase transition for different times of relaxation, calculated based on the experimental data on the droplet distribution over the radius. The work has revealed the possibility of improving the model by processing the experimental data on the size distribution of drops formed during fragmentation of a boiling water jet.
