Introduction

A turbine blade is an individual constituent that forms the turbine portion of a gas turbine or steam turbine. The blades have the task of harnessing energy from the high temperature and high pressure gas generated by the combustor. Turbine blades frequently serve as the constraining element in gas turbines.

In order to endure the challenging conditions of this environment, turbine blades frequently employ unconventional materials such as super alloys, as well as various cooling techniques that can be classified as either internal or exterior cooling, in addition to the usage of thermal barrier coatings. Blade fatigue is a significant cause of malfunction in both steam turbines and gas turbines. Fatigue arises from the mechanical strain resulting from the oscillation and harmonics occurring within the operational spectrum of machinery.

Aim of the project: DESIGN AND CFD ANALYSIS OF GAS TURBINE BLADE

In this thesis 3 naca series (NACA 2412, NACA 4412, and NACA 8412) blades were designed by using cad tool solid works and analyzed with the help of cae tool Ansys workbench in both static and flow boundary conditions for materials steel and steel 440c and in this steel is existing materials and steel 440c is new material to be analyze, and calculating results like deformation, stress, safety factor, on each model. Finally conclude thesis with required graphs and tables which NACA series blade is optimum and their limitations
