Aerodynamic Performance of an Adaptive Rear Wing at Different Angles of Attack

In this paper, computational fluid dynamics results are presented on an active rear wing designed based on the S1223 aerofoil profile. The rear wing was subjected to turbulent flow with the standard two equation k-ε turbulence model, using ANSYS Fluent software to study the aerodynamic behaviour and the force generating capabilities of the wing. The simulation was performed when the wing was set at four different angles of attack. Flow visualisation was performed to understand the nature of the air flow around the wing. Force components were additionally calculated for downforce and drag force comparison at different angles of attack, a maximum of 190.828 N and a minimum of 121.891 N of downforce was calculated. Drag force was 12.895 N at its minimum and a highest drag force of 19.518 N was calculated. It was found out that the S1223 aerofoil profile successfully aided the rear wing to generate downforce at relatively low angles of attack.
