Keywords:ANSYS, Centrifugal pump, Impeller, Performance curve, Computational fluid dynamics, BladeGen, Finite element analysis, Blade angle
Corrosive fluids, namely saline water, hydrochloric acid and methanol and non-corrosive fluids, namely, water, gasoline and kerosene can be tested for efficiency and reliability on an existing H47 centrifugal pump impeller’s performance. To analyze the pump performance, ANSYS student version 2022 software was used – wherein; head rise (H), pump speed (N), discharge rate (Q) and inlet pressure of 20-120m, 2000rpm, 144m3/h and 0 atm were respectively specified as initial and boundary conditions in the computational fluid dynamics (CFD) tool. CFD for inlet and exit blade angles of 35o, 38o, 41o and 47o, 50o, 53o were respectively simulated for all fluid type using a 7-bladed impeller to obtain contour plots and pressure and velocity distribution results of the analysis. It was deduced that the overall efficiency of the centrifugal pump depends on the outlet blade angle and fluid type, while the power used rises with both inlet and outlet blade angles. Further studies should be channeled towards analyzing the variations in N, Q, H, impeller blade number (Z) and its width, for this particular type of impeller.
