Comparison of various simulation methods of a two-phase flow in a multiphase pump

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(p = 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.
