NUMERICAL SIMULATION AND OPTIMIZATION OF SOLID-LIQUID TWO-PHASE FLOW IN A BACK-SWEPT AXIAL-FLOW PUMP

ABSTRACT
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° back-swept blade model was compared with a sludge axial flow pump in sewage treatment plant, which showed fair agreement with the simulated results.
