摘要

In this paper, some features of cavity development are presented for a case of a flow around the blade profile of the centrifugal pump impeller. Based on the photographs obtained in visualization of the cavitation centrifugal pump operation conditions, we refined the shape, volumes, and parameters of cavity growth in the centrifugal pump flow passage. Also presented are the relations characterizing the features of cavity formation in the centrifugal force field.
