▪ Abstract This review surveys the formation, motion, and persistence of trailing vortices as
relevant to the safety and productivity of air travel. It highlights findings or shifts made since …

Two numerical modelling efforts, one using a large eddy simulation model and the other a
numerical weather prediction model, are underway in support of NASA's Terminal Area …

PERSISTENT aircraft trailing vortices entail aircraft separation distances that degrade
aviation efficiency at busy airports. Because of comprehensive research efforts on both sides …

Misaligned wind turbine rotors redirect the wake, and manipulate the wake shape by
introducing a counter-rotating vortex pair. This mechanism is of great interest for improving …

Aircraft wake vortices are formed when vorticity generated by lift rolls up into two primary
trailing vortices. The two vortices have a characteristic initial separation, b,, which is …

A numerical large-eddy simulation model is under modification and testing for application to
aircraft wake vortices. The model, having a meteorological framework, permits the …

The present paper introduces the key ideas of a purely Lagrangian temperature particle
method, which includes preheating effects on fluid flow nearest a heated wall. The numerical …

The purpose of this paper is to describe the latest version of a wake-vortex eddy-dissipation
model devised by T. Sarpkaya (“New Model for Vortex Decay in the Atmosphere,” Journal of …

Wall-resolved large eddy simulations are employed to investigate the behaviour of wake
vortices and single vortices in ground proximity at a variety of wind conditions. The six …

The interaction of vortices passing near a solid surface has been examined using direct
numerical simulation. The configuration studied is a counter-rotating vortex pair approaching …
