Computational Fluid Dynamics (CFD) Analysis of Turbocharger Aerodynamics and Thermal Behaviour in Automotive Applications

Turbocharging is a vital technology for enhancing internal combustion engine (ICE) performance and efficiency while enabling engine downsizing to reduce fuel consumption and emissions. This research analyzes turbocharger systems by examining their components—turbine, compressor, intercooler, and waste-gate—and their roles in boosting engine efficiency. It explores how exhaust energy drives the turbine to compress intake air, improving power output. The study evaluates turbocharger impact on fuel economy, emissions, and engine response under various driving conditions. It also considers wheel design, material selection, and durability under high temperatures and speeds. Advanced simulations using CFD and FEA analyze airflow, pressure, and thermal behavior to optimize performance. This research affirms turbocharging’s role in creating high-performance, fuel-efficient, and environmentally sustainable engines, offering insights that support the design of next-generation automotive propulsion systems with improved thermal management and emissions control.
