Abstract
The present study conducts an analysis on the aerodynamic performance of the S1223 and Be122-125 airfoil profiles in a single-element configuration with a chord length of 0.400m for two-dimensional airflows at typical Reynolds numbers for Formula SAE (300 000, 400 000 and 800 000). The investigation employs Computational Fluid Dynamics (CFD) simulations by utilizing the Transition SST model available within the Ansys® Fluent 2021 R2 software in order to obtain the coefficients of lift, drag, pressure and skin-friction as output variables. The objective is to achieve maximum downforce generation while reducing the stall rate, thereby attaining the desired performance. In this regime, the flow conditions are categorized as "low Reynolds", which is characterized by the development of a recirculation zone named as Laminar Separation Bubble that can potentially lead to lift losses. The S1223 airfoil outperformed in terms of both downforce generation and stall rate, with the latter being evaluated using the criteria of turbulent separation position and the movement of transition location towards the leading edge.
