Investigation of the Effect of Leading-Edge Tubercles on Wingsail Performance
In this study, effects of leading edge tubercles on a 2013 America’s Cup boat wingsail are investigated by viscous Computational Fluid Dynamics (CFD). Adding tubercles on the leading edge of the sail is inspired by humpback whales, which are fast and maneuverable animals along baleen whales thanks t...
