Abstract

Abstract:- The main objective of this study is to explore the analysis of a turbocharger turbine wheel with design and materialoptimization. The study deals with static, computational fluid dynamics (CFD) and thermal analysis of the turbine blades whichmakes up the turbine phase of a turbo charger. The blades are answerable for extracting strength from the high temperature,high strain gas produced with the aid of the combustor. The turbo charger is frequently the restricting factor of turbines. Tosurvive in this difficult environment, turbine blades regularly use distinctive materials like notable alloys and lots of exceptionalmethods of cooling, which includes inner air channels, boundary layer cooling, and thermal barrier coatings. In this project, aturbine blade is designed and modelled in 3D modelling software CREO and analysis is done by using ANSYS software. Thedesign is modified by changing the base of the blade to increase the cooling efficiency. Since the design of turbo machinery iscomplex, and efficiency is directly related to material performance, material selection is of prime importance. In this project,two different fluid flow conditions (i.e., laminar and turbulent flow) are considered for present and modified models.Optimization is done by varying the materials Chromium steel, Titanium alloy and Nickel Alloy by performing coupled fieldanalysis (static + thermal) on the turbine blades for both the designs.
