Analysis of Incompressible Cascade Flows Using 'State-of-the-Art' Computer Programs.

Abstract

Two state-of-the-art computer programs, Q3DFLOW and a standard Cebeci boundary layer program as applied to aerodynamic flows in a cascade are examined. Q3DFLOW is a quasi three-dimensional finite element turbomachinery program. Only the incompressible blade-to-blade module of this program is used. The Cebeci boundary layer program is for incompressible, two dimensional, and constant viscosity flows. It is used to calculate boundary layers on a few isolated airfoils and airfoils/blades in a cascade. Experimental data and other analytical computations are compared for both programs. Additionally, the theory and operation of the Cebeci boundary layer program are presented. Keywords: Computer program analysis. (Theses).
