Theoretical analysis of incompressible flow through a radial-inlet centrifugal impeller at various weight flows

J. J. Kramer, Vasily D Prian, Chung-Hua Wu

Abstract

A method for the solution of the incompressible nonviscous flow through a centrifugal impeller, including the inlet region, is presented. Several numerical solutions are obtained for four weight flows through an impeller at one operating speed. These solutions are refined in the leading-edge region. The results are presented in a series of figures showing streamlines and relative velocity contours. A comparison is made with the results obtained by using a rapid approximate method of analysis.
