Webinar details
This webinar will discuss the numerical simulations in ANSYS Fluent software to investigate the influence of leading-edge protuberances on the wings of a NACA 2412 cross-section. Various parameters, including different wavelengths and amplitudes of protuberances, were explored, mimicking humpback whale flipper characteristics. The simulations were conducted at a velocity of 65 m/s in a turbulent flow domain with a chord-based Reynolds number of 2.29*105, using the SST k-ω models.
The results revealed notable differences in the aerodynamic performance of wings with leading-edge protuberances compared to smooth leading edges. Wings with protuberances demonstrated a higher lift coefficient (CL) and lower drag coefficient (CD) at the post-stall region.
Two specific cases with the best CL and CD after stall angle (16 degrees) were identified for optimization. The optimized wing showcased remarkable improvements in aerodynamic performance over the baseline and other wing configurations. It achieved a 23.33% increase in lift, outperforming all other defined wings. Furthermore, it reduced drag by 16% and enhanced the lift-to-drag ratio by 35% compared to the baseline wing. These results show that leading-edge protuberances (LEPs) may be able to improve wing performance after stalling. This research sheds light on the potential benefits of incorporating LEPs in wing design, offering valuable insights for applications in aerodynamics and bio-inspired engineering.
