Research on the Flow in Centrifugal Pump Impeller 5th Report, A Theory of Two-Dimensional Flow on Conical Surface in Centrifugal Pump Impeller

Abstract

In the centrifugal pump impeller, the fluid flows often in the surface of a circular cone inclining at a small angle with the plane perpendicular to the impeller axis. In this report, the author has treated such case by applying the method of series expansion, the method of the generalised displacement flow mentioned in the 2nd report, and the method of the complex velocity functions presented in the 1st report. Numerical examples are inc1uded.
