Influence of the Geometric Parameters of the Impeller of a Free-Vortex Pump on the Energy and Cavitation Characteristics of the Pump

Аннотация

Investigations of the influence of the geometrical parameters of the flow path on the integral power characteristics of a free-vortex pump are conducted by means of numerical CFD methods. Recommendations for selecting the width of the profile of the impeller blade and the number of blades are given. The cavitation features of the designed vane systems are investigated.
