Coherent vortex dynamics in a strongly interacting superfluid on a silicon chip [PDF]
Science, 2019 Following vortices around When stirred, superfluids react by creating quantized vortices. Studying the dynamics of these vortices, especially in the strongly interacting regime, is technically challenging. Sachkou et al.

Random vortex dynamics via functional stochastic differential equations [PDF]
Proceedings of the Royal Society A, 2022 In this paper, we present a novel, closed, three-dimensional random vortex dynamics system, which is equivalent to the Navier–Stokes equations for incompressible viscous fluid flows.

Superfluid vortex dynamics on a spherical film [PDF]
Physical Review A, 2021 Motivated by ongoing experimental efforts to make closed Bose-Einstein condensate (BEC) shells in microgravity environments, this work studies the energy and dynamics of singly quantized vortices on a thin spherical superfluid shell, where the overall ...

Leading-edge vortex dynamics on plunging airfoils and wings
Journal of Fluid Mechanics, 2022 The vortex dynamics of leading-edge vortices on plunging high-aspect-ratio (AR = 10) wings and airfoils were investigated by means of volumetric velocity measurements, numerical simulations and stability analysis to understand the deformation of the ...

Vortex Perturbation Dynamics [PDF]
Studies in Applied Mathematics, 1997 An initial value approach is used to examine the dynamics of perturbations introduced into a vortex under strain. Both the basic vortex considered and the perturbations are taken as three‐dimensional. An explicit solution for the time evolution of the vorticity perturbations is given for arbitrary initial vorticity.

Wing-tip vortex dynamics at moderate Reynolds numbers
The Physics of Fluids, 2021 The flow over a flat-tipped wing at three Reynolds numbers: R e = 1 × 10 4 , R e = 4 × 10 4, and R e = 1 × 10 5 is investigated using direct numerical simulation. A set of grid independent results are obtained which allow for the dynamics of the tip flow,

Aerodynamic performance of dragonfly wing model that starts impulsively: how vortex motion works
Journal of Fluid Science and Technology, 2023 The cross-section of dragonfly wings has corrugated structures. In particular, the leading-edge side of the wing consists of V-shaped structures. According to previous studies, a corrugated wing may exhibit high aerodynamic performance at low Reynolds ...

On the dynamics of vortex–droplet co-axial interaction: insights into droplet and vortex dynamics
Journal of Fluid Mechanics, 2021 Interaction of droplets with vortical structures is ubiquitous in nature, ranging from raindrops to a gas turbine combustor. In this work, we elucidate the mechanism of co-axial interaction of a droplet with a vortex ring of different circulation ...
