DESIGN MODIFICATION AND FEA ANALYSIS OF AXIAL FLOW COMPRESSOR

Laxmi ., Mr. B Bapi Raju

Abstract


An axial flow compressor is one in which the flow enters the compressor in an axial direction (parallel with the axis of rotation), and exits from the gas turbine, also in an axial direction. The axial-flow compressor compresses its working fluid by first accelerating the fluid and then diffusing it to obtain a pressure increase.

In this thesis, an axial flow compressor will be designed and modeled in 3D modeling software Pro/Engineer. The present designs will be modified by changing the aspect ratios. The present used material is Chromium Steel, it will be replaced with Titanium alloy and Nickel alloy. Structural analysis will be done on all the compressor models using steel, titanium alloy and nickel alloy to verify the strength of the compressor using finite element analysis software Ansys. CFD analysis will also be done to determine the fluid behavior in Ansys Fluent.
