Phase Distribution in the Tip Clearance of a Multiphase Pump at Multiple Operating Points and Its Effect on the Pressure Fluctuation Intensity
نویسندگان
چکیده
Tip clearance has a great effect on the flow and pressure fluctuation characteristics in multiphase pump, especially at multiple operating points. The phase distribution tip pump are revealed using CFD (computational fluid dynamics) technology high-speed photography methods. In this paper, distribution, gas-liquid two-phase velocity slip, intensity comprehensively analyzed. Results show with increase of clearance, pressurization performance is obviously deteriorated. meantime, gas accumulation mainly occurs hub, blade suction side (SS), maximum difference near impeller streamwise 0.4. addition, improves that is, larger more uniform becomes. Furthermore, leads to which closer leakage (TLF) outlet, greater degree separation clearance.
