Abstract

Plenty of research proves the potential of trailing-edge fringes in improving airfoil noise performance. However, the fringes must not degrade the airfoil’s aerodynamic performance. Therefore, the present work investigates the influence of serration and comb fringes on the aerodynamic parameters of NACA 0015 airfoil through CFD simulation at low Reynolds numbers. This study also intends to reaffirm past experimental results that might be contaminated with environmental noise. The result shows that the fringes barely affect the behavior of the lift curve’s linear region. The stall region of baseline and combed airfoils are sensitive to Reynolds number. Notably, the serrated airfoil exhibited a lower maximum lift coefficient, but the behavior of the serrated airfoil at the stall region remains unchanged as the Reynolds number varies. Both fringes have higher drag than the baseline model, which increases as the Reynolds number increases. In general, the modified trailing edge imposed an insignificant effect on the airfoil’s pitching moment. Current results indicate that the airfoil fringes offer better aerodynamic performance at lower Reynolds numbers.
