ANALYSIS OF CAVITATION PHENOMENON AS A CRITERION FOR OPTIMIZATION OF CENTRIFUGAL PUMP DESIGN

Viorel BOSTAN, Andrei PETCO

Abstract


In the given paper, the problems of describing the cavitation process by means of CFD methods are presented. The role of cavitation process study as an optimization criterion of centrifugal pump construction is also described. At the same time the theoretical part related to modeling the cavitation process in centrifugal pumps is discussed. At the end of the paper, the process of determining the NSPH value by means of CFD simulations and comparison of the results with the results of physical testing of a serial pump produced by CRIS Hermetic Pumps is presented.
