Influence of a reverse delta-type add-on device on wake vortex alleviation

Particle image velocimetry was used in a low-speed wind tunnel to investigate the effect of interactions of vortices produced by a wingtip of a half-span wing (NACA 23012 in landing configuration) and a slender reverse delta-type add-on device placed near the tip on the upper surface of the half-spa...
