The paper presents a computational analysis of the characteristics of a NACA 63 4 -021 aerofoil incorporated with sinusoidal leading-edge protuberances at Re = 14,000. The protuberances are characterized by an amplitude and wavelength of 12% and 50% of the aerofoil chord length respectively. An unsteady Reynolds Average Navier Stokes (RANS) analysis of the full-span aerofoils was carried out using Transition SST (Shear Stress Transport) turbulence model across five different angles-of-attackdoi:10.2514/6.2016-3949 fatcat:vuztvrsqmveavilqqnduv7xvhi
