Computational Fluid Dynamics-Driven Aerodynamic Enhancements for Miniature Car Design and Engineering

F1 in SchoolsTM is a STEM-focused educational program engaging students through the design and construction of a miniature F1 car. Developed with engineering expertise and endorsed by F1, it enhances STEM learning through immersive experiences. This study aims to optimize race car performance on a straight track by focusing on the aerodynamic efficiency of the front wing, car body, and sidepods. Key objectives include: minimizing drag coefficient and drag force; managing weight distribution; optimizing airflow. Using AutoCAD, each component was precisely designed, and Computational Fluid Dynamics tools were used to simulate and evaluate the car's aerodynamic performance. The final iteration of our F1 in SchoolsTM car focuses on optimizing overall airflow rather than relying on sharp aerodynamic components. This reduces turbulence, drag, and improves performance. Key features include a front wing redirecting airflow around the tires and a low-drag, backward-swept rear wing, which enhances aerodynamic efficiency.
