Abstract

A flow-conducting component such as a pump impeller is provided. Passages between vanes of the flow-conducting component include notches in the form of transitions between the vane and a common surface, such as a cover disk. The notches include a transition surface having a geometric configuration determined in accordance with a calculated load spectrum along at least a portion of the length of the notch and in accordance with a particular geometric pattern.
