Aerodynamic Performance of NACA۲۴۱۲ Airfoil: Turbulence Models and Environmental Effects

This study investigates the aerodynamic performance of the NACA۲۴۱۲ airfoil using SST k-ω, Transition SST, and k-kl-ω turbulence models. Focus is placed on how temperature variations (۲۰۰K to ۵۰۰K), turbulence intensity changes (۲% to ۸%), and surface roughness impact lift and drag coefficients, as well as flow separation tendencies. Computational simulations at ۳۰۰K, ۰ degrees angle of attack, and ۲۴۰K mesh density demonstrate minimal error, with the k-ω SST model proving most accurate in predicting lift coefficients. These findings offer insights into optimizing airfoil design under different environmental conditions.
