Flow Characteristics and Energy Loss within the Static Impeller of Multiphase Pump

The internal flow is very complex in the multiphase pump, especially static impeller, where more disorganized than that impeller wheel, and it will cause greater hydraulic losses. In order to investigate deeply rules within all kinds of losses are analyzed quantificationally pump. Based on standard SST k-ω turbulence model, selected helical axial pump as research object, used three-dimensional modeling software for through parts such suction chamber, extrusion chamber. ANSYS simulate ICEM was divide mesh press outlet moving respectively. results show wheel uniform larger vortexes appear impeller. Compared with effect rate first greater. friction loss largest among followed by dissipation loss. What’s more, shock contraction smallest, they less 20%, main turbulent proportion energy second almost same, which around 50%, can be a reference improvement performance
