Integrated Approach for the Flow Analysis in Axial Turbine Stages using Computational Fluid Dynamics (CFD )Tools

Abstract

The paper analyzes the flow through axial turbine stages and the results of two numerical simulation of steady and unsteady flow are presented. Generally analysis of turbines is carried on individual blade rows i.e nozzle guide vanes (NGV) and rotor blades. It doesn't take the nonuniformity of the exit conditions of the upstream blade vanes. Hence, turbine stage analysis must be carried out to predict the stage performance. In this study an integrated approach to analyze the turbine stages by computational fluid dynamics (CFD) tools using Fine /TURBO is carried out.
