A turbocharger is a turbine that compresses and drives air into a combustion chamber of an internal combustion engine, increasing the volumetric efficiency of a naturally aspirated engine. A compressor is connected to the exhaust turbine and speeds up the exhaust turbine with the help of exhaust gases. This allows a smaller displacement engine to burn more fuel more effectively, resulting in more power being produced. As with a conventional turbocharger, the electric turbocharger spools up and compresses air into the engine when it is activated. 3D modelling software, CREO, is used to create a turbine blade that is then analyzed using ANSYS 14.5 software. The base of the blade is modified to improve cooling efficiency in the design. When designing turbo equipment, material selection is critical since the design is complex and the efficiency is directly linked to the performance of the materials. 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 field analysis (static + thermal) on the turbine blades for both the designs.
