Numerical research on performance failure caused by gas blocking in multiphase mixed-transport pump under non-uniform inflow conditions

Zhisheng Wang,

et al.

Abstract: The helical-axial multiphase mixed-transport pump fails due to gas blocking caused by gas-liquid separation caused by cavitation under complex conditions with high gas volume fraction. This is an urgent engineering problem that needs to be addressed in the application of this pump. In order to simulate the flow structure characteristics in the channel, two types of non-uniform inflow boundary conditions were introduced. The bubble structure, velocity, and pressure under different inflow conditions were compare… Show more
