Formula SAE tri-element Rear Wing CFD

This is a deeper dive into the CFD analysis we preformed on the rear wing during the design process.

For our aerodynamic analysis for the aero package we did numerical simulation using Ansys 23R1and 22R2 with the turbulent model k-ω SST. Free-stream flow velocity was 15 m/s and 30 m/s (Re=9.08x10^5) for most models unless there was a specific condition we wanted to analyze differently. These relatively high velocities are not great for our situation, we tend to be driving, on average, far slower than these simulations (average corning speed is 11.1m/s). There are a few issues with the current way we run CFD simulations that I am changing. Like I previously mentioned we run too high of velocities but we also currently don't run mesh convergence. I am currently working on this by running an airfoil with pitot tubes along its chord in the wind tunnel here at RIT and comparing to an identical CFD sim.
