The Mathematical Modelling of Hydro-, Gas-Dynamic Processes at Flow of Two-Phase Medium in Annular Nozzles

The flow of two-phase medium in annular nozzles is considered. The mathematical model for analysis of hydro-, gas-dynamic processes is introduced. The computational field of annular nozzles and system of equations for mathematical modelling of two-phase monodisperse flows in integral form are presented. The solving of system equations carry out by procedure of assignment with using scheme Godunov–Kolgan. The results of mathematical modelling of hydro-, gas-dynamic processes (dependences of propulsion of annular nozzle and flow rate of working medium from parameters of two-phase medium), and carries at flow of two-phase medium in annular nozzle with short-cut central body are presented.
