Lehigh Formula SAE Racing Aerodynamics

I joined Lehigh University's FSAE racing team during my freshman year. I worked on the cooling system of LR-21 (FSAE competition entry of 2021). By utilizing the epsilon-NTU method and experimental effectiveness, the minimum required heat exchanger area was calculated and the radiator was selected. In addition to cooling system design, I led the first aero kit development of the team by designing the nose cone, side pod, undertray, front wings, and rear wings. Designs were validated using Star CCM+ CFD results as shown below. Aerodynamic components were manufactured using composite methods with carbon fiber skins and foam core.
