A Two-Parameters Theory of Axisymmetric Compressible Flow in Axial Turbomachines

Abstract

In this paper, a theory of a three-dimensional compressible flow in axial turbomachines with varying boundary shapes is presented, in which the assumption is made that the axial velocity profiles and the specific mass flow profiles are respectively expressible by a single parameter. For these two parameters the flow equations reduce to non-linear ordinary differential equations and can be solved numerically very easily. Comparisons with two more accurate calculations are made to investigate the accuracy of the present theory.
