摘要：
The paper examines the effects of cascade solidity, blade undercutting and blade shape on the flow in a double-row pump impeller. As the objects for investigation were chosen model impellers of feed and condensate pumps. The analysis of the flow is done by solving a direct problem for inviscid fluid and by calculating the characteristics of the spatial boundary layer in the impeller and considering the secondary overflows on the limiting disks. Criteria to estimate the hydraulic performance of impeller versions are proposed.
