Forma, 2015 Summary: Dynamics of vortices of filament type is introduced for the following three cases: deformation of a vortex filament by self-induction, entanglement of two vortex filaments by self- and mutual inductions and reconnection of two vortex filaments. The first two cases are treated by the use of vorticity equation without the viscous term, while the

Universal dynamics in the expansion of vortex clusters in a dissipative two-dimensional superfluid
Physical Review Research, 2020 A large ensemble of quantum vortices in a superfluid may itself be treated as a novel kind of fluid that exhibits anomalous hydrodynamics. Here we consider the dynamics of vortex clusters under thermal friction and present an analytic solution that ...

How trapped particles interact with and sample superfluid vortex excitations
Physical Review Research, 2020 Particles have been used for more than a decade to visualize and study the dynamics of quantum vortices in superfluid helium. In this work we study how the dynamics of a collection of particles set inside a vortex reflects the motion of the vortex.

Parametric resonance in the dynamics of an elliptic vortex in a periodically strained environment [PDF]
Nonlinear Processes in Geophysics, 2017 The model of an elliptic vortex evolving in a periodically strained background flow is studied in order to establish the possible unbounded regimes.

Applications of point vortex equilibria: blocking events and the stability of the polar vortex [PDF]
Tellus: Series A, Dynamic Meteorology and Oceanography, 2015 The present study investigates non-linear dynamics of atmospheric flow phenomena on different scales as interactions of vortices. Thereby, we apply the idealised, two-dimensional concept of point vortices considering two important issues in atmospheric ...

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.

Nonlinear gyrotropic vortex dynamics in ferromagnetic dots [PDF]
, 2010 The quasistationary and transient (nanosecond) regimes of nonlinear vortex dynamics in a soft magnetic dot driven by an oscillating external field are studied.
