Abstract:
In this study, the effects that the blade width, the blade number, and the impeller diameter have on the steady state liquid flow in three-dimensional impeller, and combined impeller and volute were investigated. The continuity and Navier-Stokes equations with the k-ε turbulence model and the standard wall functions were used by mean of ANSYS-CFX code taking into account of the suction pressure variation as a function of the valve volume flow rate. The achieved results reveal that the selected key design parameters have an impact on the head, the brake horsepower and the overall efficiency of the centrifugal pump. To valid the developed approach, the results of numerical simulation were compared with the experimental results considering a special case of combined impeller and diffuser.
