Dynamics of a vortex dipole in a holographic superfluid
Journal of High Energy Physics, 2021 We use holography to investigate the dynamics of a vortex-anti-vortex dipole in a strongly coupled superfluid in 2+1 dimensions. The system is evaluated in numerical real-time simulations in order to study the evolution of the vortices as they approach ...

Dynamic Characteristics and Effect on Thrust of Jet Tail Vortex Ring for Pump Jet Propulsion
Frontiers in Energy Research, 2022 When a pump is propelled by a propeller, the nozzle flooding of the jet wake area will produce a turbulent quasi-sequence structure and have a certain impact on the outflow field structure and thrust characteristics of the water jet propulsion pump.

Vortex dynamics of wakes [PDF]
Nelineinaya Dinamika, 2006 Summary: Several problems related to the dynamics of vortex patterns as observed in wake flows are addressed. These include: The universal Strouhal-Reynolds number relation. The Hamiltonian dynamics of point vortices in a periodic strip, both the classical two-vortices-in-a-strip problem, which gives the structure and self-induced velocity of the ...

Dynamics of global and local vortices with orientational moduli
Journal of High Energy Physics, 2021 The dynamics of both global and local vortices with non-Abelian orientational moduli is investigated in detail. Head-on collisions of these vortices are numerically simulated for parallel, anti-parallel and orthogonal internal orientations where we find ...

The Interaction of Two Surface Vortices Near a Topographic Slope in a Stratified Ocean
Fluids, 2017 We study the influence of bottom topography on the interaction of two identical vortices in a two-layer, quasi-geostrophic model. The two vortices have piecewise-uniform potential vorticity and are lying in the upper layer of the model. The topography is

Simplified model for helical vortex dynamics in the wake of an asymmetric rotor
Flow, 2023 Helical vortex systems, such as those found in the wakes of wind turbines, helicopter rotors and propellers, are subject to instabilities that lead to pairing between adjacent vortex loops.

Flow Visualisation around Spinning and Non-Spinning Soccer Balls Using the Lattice Boltzmann Method
Proceedings, 2018 The drag and lift of footballs have been mainly measured by wind tunnel tests. In the present study, computational fluid dynamics (CFD) and the lattice Boltzmann method were used to visualise the wakes of spinning and non-spinning footballs and analyse ...

Geometric Characterization of Atmospheric Islands Formed by Two Point Vortices
AxiomsGenerically, in a system with more than three point vortices, there exist regions of stability around each vortex, even if the system is chaotic. These regions are usually called stability islands, and they have a morphology that is hard to characterize.
