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

A.L. Kartashev, M.A. KartashevaThe flow of two-phase medium in annular nozzles is considered. The mathematical model for analysis of hydro-, gas-dynamic processes at flow of the medium under consideration is introduced. The computational field of annular nozzles and system of equations for mathematical modeling of two-phase monodisperse flows in integral form are presented. The solution of the system equations is carried out by procedure of assignment with using scheme Godunov - Kolgan. The results of mathematical modeling of hydro-, gas-dynamic processes (dependences of propulsion of annular nozzle and flow rate of working medium from parameters of two-phase medium), flowing at two-phase medium in annular nozzle with short-cut central body are presented.Full text
