AN INVESTIGATION OF FLOW VISCOSITY EFFECT ON SOME PROPERTIES OF FLUID FLOW THROUGH TWO DIMENSIONAL CASCADE OF GAS TURBINE BLADING

In this paper the effects of flow viscosity on the property of fluid flow through gas turbine blading in two dimensional modes and for a sample of blade was investigated. The fluid used in this research is air which is considered as ideal gas for steady state flow condition. This analysis is done by a computer program which is developed for this purpose. This program has two arithmetic stages, so that at first step the inviscid part is computed then obtained data is used to compute the Viscose part one. This analysis is done for two cases separately and comparison results are shown as tables and graphs. The discussed properties in this paper are: Mach number, Pressure and Temperature.
