Undertray lateral diffussers
The idea:
This project is preliminary research toward designing an underfloor package for Brown Formula Racing. The goal is to generate downforce from the undertray, which the team has never attempted before. I started by researching how professional race car floors work, analyzing the geometry of diffusers, tunnels, and floor edges to understand the aerodynamic principles involved.
The process:
“I designed the undertray geometry directly in STAR-CCM+ CAD, working through several iterations. Each version was based on what I learned from analyzing professional undertrays and from the simulation results of previous iterations.
I ran CFD simulations to analyze airflow behavior, velocity distributions, and pressure fields underneath the car. With each iteration, I developed a better understanding of how small geometry changes affect the flow structures that generate downforce, things like diffuser angle, tunnel shape, and edge treatment.
The result:
This project is still in progress. The research and simulation work here is laying the groundwork for the team's first full underfloor aero package, which I'm now developing alongside my co-lead in aerodynamics.
