Role of interstitial pinning in the dynamical phases of vortices in superconducting films
(2013-06-01)
We analyze the vortex dynamics in superconducting thin films with a periodic array of pinning centers. In particular, we study the effect of anisotropy for a Kagomé pinning network when longitudinal and transverse transport ...
On the wake-induced vibration of tandem circular cylinders: the vortex interaction excitation mechanism
(CAMBRIDGE UNIV PRESS, 2010)
The mechanism of wake-induced vibrations (WIV) of a pair of cylinders in a tandem arrangement is investigated by experiments. A typical WIV response is characterized by a build-up of amplitude persisting to high reduced ...
Regimes of near-wall vortex dynamics in potential flow through gaps
(2008)
A two-dimensional problem of the motion of a single vortex near an infinite straight wall with singular gaps is solved both analytically, using a point-vortex approach, and numerically based on the method of contour surgery ...

Three-dimensional sand ripples as the product of vortex instability

Mode selection in trailing vortices: harmonic response of the non-parallel Batchelor vortex
(Cambridge Univ. Press, 2016)
In the present study, the response of model trailing vortices subjected to a harmonic forcing is studied. To this purpose, a globally stable non-parallel Batchelor vortex is considered as the baseflow. Direct numerical ...
A family of vortex rings and a variational application to potential flows around three-dimensional bodies
(Associação Brasileira de Engenharia e Ciências Mecânicas - ABCM, 2008)
A variational formulation and solution of general three-dimensional potential flows gave rise to the construction of a special family of ‘trial functions’. This family is composed by circular-sector vortex rings, here named ...
Vortex dynamics and scalar transport in the wake of a flat-plate controlled by a vibrating trailing-edge flap
(Elsevier, 2020)
We investigate the onset and development of vortical flow disturbances introduced into the wake of a horizontally fixed flat-plate by means of the controlled motion of a trailing edge flap. The vibrating mechanics of the ...
A singular vortex Rossby wave packet within a rapidly rotating vortex
(2017)
This paper describes the quasi-steady regime attained by a rapidly rotating vortex after a wave packet has interacted with it. We consider singular, nonlinear, helical, and shear asymmetric modes within a linearly stable, ...
