Heat Transfer Analysis of Turbine Blade Using CFD
摘要
In this study, heat transfer analysis for turbine blades was carried out using the Computational fluid dynamics approach. For the geometric modeling, Solidworks 2022 was used and an ANSYS workbench was employed for the simulation of a turbine blade. The materials must endure high vibrations, temperature, force, and pressure. This study aims to investigate how heat is transferred across the surface of the turbine blade and identify areas that exhibit notable temperature, stress, and strain differences. The analysis considers both convective heat transfer, which occurs due to the flow of hot gases, and conductive heat transfer which takes place within the blade material. So, two materials were used for the analysis, i.e., Titanium alloy and Inconel 718. After meshing, the element's number is 279357 and the node's number is 476430. A numerical study was carried out for the turbine blade designed for a gas turbine under the load of 5000 N with a rotational velocity of 1000 rad/s. Further, plastic deformation, stress, and strain were computed. So, the Titanium alloy has higher deformation, stress, and strain than Inconel 718. According to the study, Inconel 718 is a suitable material for turbine blades. The results obtained from the CFD simulations provide valuable insights into the thermal behavior of the turbine blade. CFD analysis empowers engineers and designers to optimize cooling design, material selection, and operating conditions for turbine blades, leading to enhanced performance, efficiency, and lifespan. This study also adds to the overall understanding of heat transfer in gas turbine systems.
