On the Flow in the Impeller of Centrifugal Type Hydraulic Machinery : 7th Report, One Method for Calculating the Flow of Two Dimensional Impeller

Abstract

This paper deals with one method for calculating the flow in the two dimensional impeller of centrifugal type hydraulic machinery on the basis of the singularity method. This method has such a merit that the vortex, velocity and pressure distributions can be calculated without difficulty, even if the impeller has a number of vanes or splitter vanes. The calculations were performed with respect to several impellers and their results were respectively compared with the calculated ones by the conformal mapping or experimental one.
