Computational Fluid Dynamics Analysis of Vehicle with Coolers

The optimization of vehicle aerodynamics plays a crucial role in enhancing fuel efficiency, reducing emissions, and improving overall performance. However, numerous problem areas, such as flow separation and large areas of inefficiency, hinder the seamless airflow around vehicles, leading to increased drag and compromised aerodynamic performance. This report focuses on utilizing Computational Fluid Dynamics (CFD) analysis to identify these problem areas and explore the potential of vortex generator air curtains and strakes as effective solutions to enhance vehicle aerodynamics. By understanding the impact of these innovative technologies, we aim to unlock new possibilities for improving efficiency and reducing the environmental footprint of vehicles. This works utilizes CFD commercial solver ANSYS FLUENT to address influence of these parts on a detailed vehicle CAD model. Moreover, three coolers situated in the radiator (radiator cooler), above the wheel (oil cooler) and in the rear part of the model (intercooler) are modelled using porous media.
