Abstract: The design phase of developing an automobile emphasizes on the importance of vehicle aerodynamics which directly affects the overall performance and efficiency. The drag coefficient (Cd) plays a huge role in this aspect and its reduction is crucial in ensuring stability of the vehicle. Our project focuses on the flow analysis over a generic sedan model with an aim to reduce the drag acting on it. The model is created on CATIA and then imported to ANSYS for analysis. It is tested initially as per the prescribed boundary conditions and their contours (pressure and velocity) are studied in order to understand the airflow around the body. A new set of boundary conditions is incorporated following the baseline analysis. The mesh characteristics are also varied to study its effect on drag reduction. This project discusses, in detail, the various experimental, theoretical and numerical processes involved in the computational fluid dynamic study of a sedan model.
