This article reviews the characteristics and behavior of counter-rotating and corotating vortex
pairs, which are seemingly simple flow configurations yet immensely rich in phenomena …

This paper discusses the problem of wake vortices shed by commercial aircraft. It presents a
consolidated European view on the current status of knowledge of the nature and …

Two parallel Gaussian vortices of circulations Γ1 and Γ2 radii a1 and a2, separated by a
distance b may become unstable by the elliptical instability due the elliptic deformation of …

The present thesis constitutes a step forward in advancing the frontiers of knowledge of fluid
flow instability from a physical point of view, as a consequence of having been successful in …

The viscous evolution of two co-rotating vortices is analysed using direct two-dimensional
numerical simulations of the Navier–Stokes equations. The article focuses on vortex …

Results of high-resolution numerical simulations of aircraft wake vortex evolution and decay
in different regimes and atmospheric conditions are presented. The different cases comprise …

The decay of trailing vortex pairs in thermally stably stratified environments is investigated by
means of large eddy simulations. Results of in-situ measurements in the wakes of different …

A general theoretical account is proposed for the zigzag instability of a vertical columnar
vortex pair recently discovered in a strongly stratified experiment. The linear inviscid stability …

The objective of this study is to perform direct numerical simulations (DNS) of the three-
dimensional short-wavelength elliptic instability developing in a counter-rotating vortex pair …

In this article we analyze the cooperative three-dimensional short-wave instabilities
developing on concentrated vortex dipoles that have been obtained by means of two …
