Wavy Leading Edge (WLE) Influence on a Rectangular Wing Using an Unsteady Analysis Approach
A rectangular wing with Wavy Leading Edge (WLE) effect was investigated experimentally and numerically. This research was carried out with the NACA 0018 profile. The morphology of humpback whale flippers, which are blunt and rounded in a specific pattern, inspired the design of the WLE. The rectangu...
