Numerical Modeling of High-Enthalpy Two-Phase Flow in a Channel with Transverse Injection of a Reactive Liquid

The authors have performed numerical modeling and have analyzed, from the results of calculation, distinctive features of two-phase flow in a channel of constant cross section upon traverse injection of a reactive liquid through spray injectors. A model hydrocarbon fuel with thermophysical properties similar to TS-1 kerosene has been considered as the reactive liquid. The characteristics of spraying and evaporation of liquid droplets in a high-enthalpy subsonic air flow have been obtained by mathematical modeling, and an analysis has been made of the quality of mixing and the intensity of combustion of a two-phase mixture. Also, the regularities of the influence of the number of injectors and the pressure difference in them and of the mass flow rate of the reactive liquid on the intensity of processes occurring in the channel have been obtained.
