Abstract

The centrifugal pump’s performance is affected by different parameters and the flow inside the pump is complicated. The ANSYS computational fluid dynamics technique is an excellent tool to solve complex flows inside the pump and aid engineers in designing and predicting the pump’s optimal performance for specific applications. The objective of the study is to conduct parametric evaluation with a specific focus to determining the effect of the various impeller blade numbers on the performance curve of the centrifugal pump. The iterations made were the impeller blade numbers and the volumetric flow rates. The rotational speed of 1450 rpm was utilised, and the head rise of 20 m. Outcome: An increase in blade numbers translates to an increase in head and pressure of the system. Furthermore, it was discovered that when the blade numbers are increased, the power consumption of the pump also increases. The best efficiency points were observed for the 4, 6 and 8-blade configurations at the volumetric flow rate of 396 m3/hr while the 10-blade configuration best efficiency was at 324 m3/hr. Beyond the best efficiency points the efficiency for the 4 and 6-blades dropped marginally while the 8 and 10-blades dropped steeply.
