Nondiffracting supertoroidal pulses and optical “Kármán vortex streets”

open access: yesNature Communications
Supertoroidal light pulses, as space-time nonseparable electromagnetic waves, exhibit unique topological properties including skyrmionic configurations, fractal-like singularities, and energy backflow in free space, which however do not survive upon ...

Fish Swimming in a Kármán Vortex Street: Kinematics, Sensory Biology and Energetics. [PDF]

open access: yesMar Technol Soc J, 2017
Fishes often live in environments characterized by complex flows. To study the mechanisms of how fishes interact with unsteady flows, the periodic shedding of vortices behind cylinders has been employed to great effect.

Dynamics of Particle-Laden Wake Flow in a Karman Vortex Street Considering the Droplet-Vortex Interactions [PDF]

open access: yesJournal of Applied Fluid Mechanics, 2022
To investigate the dynamics of droplet-vortex interactions in particle-laden Karman vortex street flows, the simulations were carried out by using Euler-Lagrange approach, which was validated by the available experiments and numerical results.

Interaction of turbulent kinetic energy and coherent motion in the near field of the cylinder wake

open access: yesMechanics & Industry, 2023
The far aim of the study is to experimentally assess the exchange of turbulent kinetic energy (TKE) of a wake behind a cylinder, as a function of the upstream flow.

A Model for the von Kármán Vortex Street [PDF]

open access: yes, 1981
In the wake of a two-dimensional bluff body placed in a uniform stream, for sufficiently large but not too large flow velocity a distinctive pattern of vorticity is observed.

Kármán vortex street in a two-component Bose–Einstein condensate

open access: yesNew Journal of Physics, 2019
Vortex shedding from a moving obstacle potential in a two-component Bose–Einstein condensate is investigated numerically. For a miscible two-component condensate composed of ^23 Na and ^87 Rb atoms, in the wake of obstacle, the Kármán vortex street is ...
