This study investigates the aerodynamic and aeroacoustic performance of a NACA 2412 airfoil with trailing edge serrations using a computational approach. A three-dimensional model is analyzed at an angle of attack of 5° and a freestream velocity of 45 m/s. The flow field is simulated using the SST k–ω turbulence model, and far-field noise is predicted using the Ffowcs Williams–Hawkings (FW-H) acoustic analogy. The results for the serrated configuration are compared with a baseline airfoil to evaluate the impact of geometric modification. Aerodynamic analysis shows a slight increase in drag and a marginal reduction in lift for the serrated case. However, aeroacoustic results indicate a consistent broadband noise reduction across multiple receiver locations, with noticeable improvements in the low-to-mid frequency range. The findings suggest that trailing edge serrations effectively reduce noise by altering flow structures near the trailing edge while maintaining acceptable aerodynamic performance.
