Short abstract: The effect of undulation placement (leading edge, trailing edge, or leading and trailing edges) on the wing performance and the wingtip vortex was investigated. Experiments were performed at the University of Dayton Low-Speed Wind Tunnel on undulated wings where the NACA 0012 airfoil cross section is preserved along the wingspan.

Short abstract: Most leading-edge tubercles studies involve serrated-type or undulated leading edges where the airfoil cross-section is destroyed unintentionally. Experimental investigations were performed at the University of Dayton Low Speed Wind Tunnel (UD-LSWT) on an undulated wing where the NACA 0012 airfoil cross-section is preserved along the wingspan.

Short abstract: The distribution of mean and fluctuating quantities in the free shear layer wake of airfoil-preserved undulated wings are investigated using Particle Image Velocimetry (PIV) at the University of Dayton Low Speed Wind Tunnel (UD-LSWT). Prior work on wings with airfoil-preserved undulations revealed that wings with trailing edge undulations and wings with leading and trailing edge undulations had higher aerodynamic efficiency than the wings with leading edge undulations.
