Previously, the aero shell design has fulfilled an optimization of the nose tip height, relative to the maximum height of the nose; ANSYS Fluent was used to analyze the turbulent flow about 21 CAD models differing only in nose tip height. It was found through quadratic regression analysis that the optimal nose tip height (for minimum drag values) would be 28.9% of the maximum nose height. Currently, 4 CAD model assemblies have been generated to study the flow entering the wheel wells of the vehicle, with CFD analysis planned for Saturday, November 18. The first two models examine whether changing the edge leading into the wheel wells from sharp to rounded would effect the flow entrainment into the wheel wells; the second two models look into adding extra devices and their impact upon the aforementioned flow entrainment. After the wheel well flow entrainment has been minimalized, there are three more optimization studies that will be conducted by the end of the semester: (1) the flow exit from the wheel wells will be optimized for minimal drag and maximum downforce, including wheel well louvres and top-mounted, horizontal ducts; (2) the design of the canopy and driver ventilation, will be optimized for minimal drag and size; and (3) the general shaping of the entire vehicle will be refined by adding varying degrees of camber and edge filleting.
