Abstract:
Based on Navier-Stokes equation set and standard k-ε turbulence model, the full passage numerical simulation of a high-speed centrifugal pump was performed in different working condition. Two different models and their simulations were designed to verify the influence of inducer on the performance of the high-speed centrifugal pump. The variation of velocity and the pressure fields inside the pump are analyzed in detail so as to predicate the pump performance curve. The analysis result shows that the high-speed pump with inducer have better flow characteristics under the same flow rate and the inducer can improve the efficiency and head of the pump. The performance of high-speed pump can be predicted by numerical calculation method. The conclusions made above were verified by hydraulic test.
