The in-ground-effect (IGE) aircraft wake vortex poses great hazards to airplanes. Especially
when the vortex column is deformed with a long wavelength, the vortex core position is …

Aircraft wake-vortex evolution in ground proximity is investigated numerically by means of
large-eddy simulations. The simulations are performed either with a flat ground or with …

Wake-vortex evolution during approach and landing of a long range aircraft is investigated.
The simulations cover final approach, touchdown on the tarmac, and the evolution of the …

It is well-known that the long-lasted aircraft wake vortex above the airport runway
jeopardizes flight safety. Therefore, the research on the enhancement of wake vortex decay …

To mitigate the risk of wake vortex encounters during final approach, so-called plate lines
have been developed. Wake vortices generated by landing aircraft induce secondary …

Large-eddy simulations (LES) have been employed to investigate the far-field four-vortex
wake vortex evolution over 10min behind an aircraft formation. In formation flight scenarios …

Environmental crosswind can greatly affect the development of aircraft wake vortex pair.
Previous numerical simulations and experiments have shown that the nonlinear vertical …

Purpose From pilot reports, field measurements and numerical simulations, it is known that
wake vortices may persist within the glide path in ground proximity, leading to an increased …

In this paper, we investigate the impingement of a two-dimensional (2-D) vortex pair
translating downwards onto a horizontal wall with a wavy surface. A principal purpose is to …
