Experimental and Analytical Investigation of Three-Dimensional Inviscid Effects in Turbomachinery

Abstract

A relatively simple, rapid method for predicting the three- dimensional flow effects in turbomachinery of arbitrary configuration was investigated. Although the two-dimensional cascade is a satisfactory approximation for the design and analysis of some types of turbomachines, the flow through devices such as propeller pumps, inducers, and fans for turbofan engines may deviate significantly. No solution exists for the complete, unified three-dimensional flow problem, but analyses which include the effect of three- dimensional flows have been developed. These typically involve lengthy numerical solutions for specialized cases and are not optimum for design nor for a unified study of three-dimensional flow trends.
