Abstract


This article outlines the methodology for developing the geometry of a centrifugal pump inducer through the application of Computational Fluid Dynamics with optimization methods. Numerical simulation of the fluid flow in a centrifugal pump was carried out. Different optimisation algorithms based on the response surface were compared with the best design point. A digital validation of the obtained geometrymodelwas conducted. Cavitation tests of the pump with the original design and with the inducer were performed. The usage of the resulting inducer led to a decrease in Net Positive Suction Head by 0.5 mH2O at the Best Effective Point, which is in accordance with the acquired technical requirements. The obtained inducer was utilized to a produced serial centrifugal canned motor pump by CRIS Hermetic Pumps.
