On the Folw in the Impeller of Centrifugal Type Hydraulic Machinery : 6th Report, The Three-Dimensional Impeller

Abstract

This paper deals with the theory and the experiment or the three-dimensional impeller, that is the impeller with blades or inconstant height, of centrifugal type hydraulic machinery. The theory is developed by using conformal mapping under the assumption that the flow does not differ much from a two-dimensional potential one, and assuming that the displacement flow is not aflected by the inconstant blade height, but the through flow is affected by it. The calculated results of this theory and two-dimensional one were compared with their respective, experimental results, proving good agreement among them.
