Topic : Design and Analysis of Axial Flow Compressor Blade Using Different Aspect Ratios with Different Materials

Authors:K.Sravanmathur || R.Murugan, V.S.Hariharan

Abstract:An axial flow compressor is a pressure developing machine. It is a rotating, airfoil-based compressor in which the working fluid principally flows parallel to the axis of rotation. This is in contrast with other rotating compressors such as centrifugal compressors, axial flow centrifugal compressors and mixed-flow compressors where the air may enter axially but will have a significant radial component on exit. The energy level of air or gas flowing through it is increased by the action of the rotor blades which exert a torque on the fluid which is supplied by an electric motor or a steam or a gas turbine. In this work, an axial flow compressor is designed by varying aspect ratios (ratio of blade height to axial chord length) where blade height is kept constant and 3D models are modelled using Pro/E. The present material used is Chromium Steel it is replaced with Titanium alloy and Nickel alloy. CFD analysis is done to verify the flow characteristics of fluid under turbulent conditions by applying the mass flow rate and inlet pressure, outlet pressure, velocity and mass flow rates. Structural analysis is done on the compressor models to verify the strength of the compressor for all the materials chromium steel, titanium alloy and nickel alloy by applying pressure which is output from CFD analysis. The analysis is done in Ansys..

Keywords: Axial flow compressor, aspect ratios and CFD analysis
