Introduction

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

In order to endure in this challenging setting, turbine blades frequently employ unconventional materials such as super-alloys, as well as various cooling techniques including internal air channels, boundary layer cooling, and thermal barrier coatings.

Blade fatigue is a significant cause of malfunction in both steam turbines and gas turbines. Fatigue arises from the tension generated by the vibrations and resonances occurring within the operational spectrum of machinery. Friction dampers are employed to safeguard blades from the intense dynamic pressures.

Aim of the project: Design and Thermal Analysis of Turbine Blades

In this project, we built and analyzed two distinct turbine blades (NACA1412, NACA 6412, and NACA 5415) under identical boundary circumstances. We examined their performance using three different materials, including steel and two additional materials.

We are currently computing the data for deformation, stress, and safety factor for all materials. In order to prevent resonance, we also compute their respective natural frequency values. In addition, the thermal loading conditions encompass the total temperature and total heat flux values. Based on the information provided, we can determine the best suitable material and model that will yield high efficiency.
