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 …

Large-eddy simulations of a coherent counter-rotating vortex pair in different environments
are performed. The environmental background is characterized by varying turbulence …

This study investigates the influence, on aircraft wake vortex behavior, of atmospheres that
are stably stratified (neutral to very strong) and weakly turbulent, by means of large-eddy …

An explanation for the origin and number of clumps along the equatorial ring of Supernova
1987A has eluded decades of research. Our linear analysis and hydrodynamic simulations …

We conduct direct numerical simulations and study the evolution of a pair of counter-rotating
vortices in a stratified and turbulent environment beyond the first vortex linking (which is due …

Long, straight, anti-parallel vortex tubes, with balanced profiles and a local perturbation, are
simulated using the Navier-Stokes equations and evolve into a chain of spiral vortex rings …

In this work, we investigate the approach of a descending vortex pair to a horizontal ground
plane. As in previous studies, the primary vortices exhibit a 'rebound', due to the separation …

Processes of vortex reconnection on a helical vortex, which is formed in a swirling flow in a
conical diffuser, have been studied experimentally. It has been shown that reconnection can …

Results are presented from an experimental study on the dynamics of pairs of vortices, in
which the axial velocity within each core differs from that of the surrounding fluid. Co-and …

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 …
