Cavitation phenomena and Bubbles Dynamic in Turbomachinery

Cavitation in centrifugal pumps is regarded as the main cause of deterioration of important parts of the pump, including impellers and volute. In order to examine this phenomenon, first a two-stage BB2 pump of the API design was experimentally investigated in terms of head and flow rate in single-phase flow and flow with cavitation, then the results were compared to those of the model created in the ANSYS CFX software environment. In addition, the Stepanov and Dixon theories were employed t...
