Three Dimensional Internal Flows in Turbomachinery. Volume I.

Abstract

This report describes an efficient numerical scheme developed for investigating secondary flows, and outlines the design of an experimental set-up for obtaining detail in channel three dimensional secondary flow measurements. The analysis applies to inviscid internal rotational flow fields and leads to a very efficient numerical scheme for predicting the secondary flow phenomena. The analysis is applied to the rotational flow in a 90 deg bend with rectangular cross-section and then compared with the experimental data. It is concluded from the comparison that the physics of the secondary flow problem are well represented in the analysis. The analysis can be adapted with some modifications to variable area ducts, and turbomachinery passages. (Author)
