On the Flow in a Centrifugal Impeller : 2nd Report, Effects of Change in Impeller Width

Abstract

In this paper, authors have presented a method to analyze the flow in a variable width centrifugal impeller. This analysis has been based on Hoffmeister's method and new considerations have been added to the analyses of through flow and displacement flow. Authors have applied this method to the calculation of nenviscous and incompressible fluid flow through the centrufugal impeller with thin logarithmic spiral vanes, and shown the velocity and pressure distributions on the vane surfaces and influences of the impeller width ratio on the performance of the impeller.
