NUMERICAL AND CAVITATION ANALYSIS OF A CENTRIFUGAL PUMP
Keywords:
Cavitation, Centrifugal Pump,, CFD,, Numerical analysis,Abstract
This paper aims at numerically predicting the flow behavior of the pump. Further validation of the available experimental results and inspection of the effect of change in variation of parameters along with cavitation phenomenon was numerically studied and simulated. The said objective is accomplished by creating the three-dimensional geometry of the pump in CAD package. Hybrid discretization was carried out and the results are analyzed and numerically obtained by using ANSYS Fluent R15. The effect of variation of rotational speed, discharge, and change in number of blades individually on the performance of the pump was also studied to get clear idea about the performance of the pump and the behavior of the fluid inside the pump. The cavitation phenomenon is also numerically modelled on the three-dimensional impeller geometry to analyze inception and progress of cavitation bubbles.
