The Rayleigh–Taylor instability of two-dimensional high-density vortices [PDF]
, 2005 We investigate the stability of variable-density two-dimensional isolated vortices in the frame of incompressible mixing under negligible gravity. The focus on a single vortex flow stands as a first step towards vortex interactions and turbulent mixing ...

Faults Get Colder Through Transient Granular Vortices
Geophysical Research Letters, 2018 Fault temperatures govern their weakening and control the dynamics of earthquakes during slip. Despite predictions of significant temperature rise within fault gouges during earthquake events, observations of frictional melting zones along exhumed faults

Control of Flow around an Oscillating Plate for Lift Enhancement by Plasma Actuators
Applied Sciences, 2019 During insect flight, a feathering motion of the wing’s controls vortex shedding for lift enhancement. In this study, in order to control the flow around a wing flapping with simplified sinusoidal motion, plasma actuators were introduced to ...

Ellipsoidal vortices in rotating stratified fluids : beyond the quasi-geostrophic approximation [PDF]
, 2015 Support for this research has come from the UK Engineering and Physical Sciences Research Council (grant number EP/H001794/1).We examine the basic properties and stability of isolated vortices having uniform potential vorticity (PV) in a non-hydrostatic ...

Fluids, 2023 A bubble expanding and collapsing near a solid boundary develops a liquid jet toward the boundary. The jet leaves a torus bubble and induces vortices in the liquid that persist long after the bubble oscillations have ceased.

Quasi-geostrophic vortices in compressible atmospheres [PDF]
, 2005 This paper considers the effect of an exponential variation in the background density field (as exists in compressible atmospheres) on the structure and dynamics of the quasi-geostrophic system, and compares the results with the corresponding Boussinesq ...

Released power in a vortex-antivortex pairs annihilation process
Revista UIS Ingenierías, 2020 In this paper, we studied the power dissipation process of a Shubnikov vortex-antivortex pair in a mesoscopic superconducting square sample with a concentric square defect in presence of an oscillatory external magnetic field. The time-dependent Ginzburg-

Experiments on a barotropic rotating shear layer. Part 1. Instability and steady vortices [PDF]
, 1999 The barotropic shear layer in a rotating fluid is studied in a laboratory experiment. Through the rotation of circular sections in the base and lid of a circular tank relative to a background rotation of the entire system, a vertical layer of strong ...
