Vortices are a ubiquitous feature in complex flows and turbulence, but their dynamics are
challenging to study due to their typically transient nature. Here, we perform a detailed study …

We investigate coarsening dynamics in the two-dimensional, incompressible Toner-Tu
equation. We show that coarsening proceeds via vortex merger events, and the dynamics …

Flight research of the characteristics of trailing vortices, generated by heavy jet transport
aircraft in cruising flight, was conducted. Trailing vortex velocities were derived by vectorial …

Heavy particles in a turbulent flow tend to leave regions of high vorticity and cluster into
regions of high strain. The consequences of such clustering have been studied in a variety …

Strongly coupled dusty plasma medium is often described as a viscoelastic fluid that retains
its memory. In a flowing dusty plasma medium, vortices of different sizes appear when the …

The effect of compressibility in the process of vortex merging is discussed. In past, in the
incompressible limit, it has been observed that the merging of a collection of intense point …

Flight data of trailing vortices, generated by Heavy Category jet transport airplanes in high
altitude cruising flight, has been measured by an instrumented research airplane. Earlier …

Vortex flow has been widely observed in fluid systems in confined regions. In this study, an
Oseen-like vortex in a confined compressible fluid was numerically investigated to …

This paper presents a numerical study of the advection of passive and active particles by
three and four equal vortices located on the vertices of a polygon. The vortices, which have …
