Numerical simulation and optimization of solid-liquid two-phase flow in a back-swept axial-flow pump
Keyword(s):
The simulation study is proposed to analyze the wear property of the axial flow pump using the sewage as medium. Different axial flow pumps are designed with different back-swept angles, of which are 40?, 65?, and 90?. Numerical simulation results showed the relationship between solid volume fraction and back-swept angle on the pressure/suction surface, as well as the particle diameter. To validate the correctness of numerical investigation, the result of the 65? backswept blade model was compared with a sludge axial flow pump in sewage treatment plant, which showed fair agreement with the simulated results.
