Evaluation of aircraft wing-tip vortex using PIV
Published 2009“…Particle image velocimetry was used in a wind tunnel to measure the tip vortex velocity field and hence investigate the flow structure in a wake of aircraft half-wing model. The purpose of this investigation is to evaluate the main features of the lift generated vortices in order to find ways to alleviate hazardous wake vortex encounters for follower airplanes during start and approach such that the increase in airport capacity can be achieved. …”

Effect of differential spoiler settings (DSS) on the wake vortices of a wing at high-lift-configuration (HLC)
Published 2011“…Result of the outboard loading case 2 shows a limited effect in terms of the wing tip vortex structure. This can be due to the relatively large separation distance between the wing tip and the deployed spoilers, preventing the spoiler wake/wing tip vortex interaction in the near field.…”
