【 摘 要 】

The article presents a mathematical model of a two-phase flow in a multiphase helico-axial pump. In this paper, the model of a multiphase incompressible fluid flow (ρ = const) were used. Numerical simulation is based on solving discrete anagoges of the basic hydrodynamic equations. The hydrodynamic simulation of the described mathematical model was performed in two ways: in a simplified form, using a multiphase volumeoffluid model (VOF), and the segregated flow method. The results of the calculation of two-phase flows for various values of the gas contaent are given. The influence of gas content on the pump performance and its pressure is considered. A comparison of calculation results of two methods of hydrodynamic simulation of two-phase flow is shown.
