Dipole dynamics in the point vortex model [PDF]

, 2022
At the very heart of turbulent fluid flows are many interacting vortices that produce a chaotic and seemingly unpredictable velocity field. Gaining new insight into the complex motion of vortices and how they can lead to topological changes of flows is ...

Time-resolved plasmon-assisted generation of optical-vortex pulses

Scientific Reports, 2023
The microscopic mechanism of the light-matter interactions that induce orbital angular momentum (OAM) in electromagnetic fields is not thoroughly understood.

Asymmetric dual Bloch point domain walls in cylindrical magnetic nanowires

APL Materials, 2022
Cylindrical magnetic nanowires have been studied extensively over the past ten years due to the presence of domain walls with novel topology and outstanding dynamic properties.

Long Time Scale Fluctuation in the Irregularity of Vortex Shedding （Different Vortex Shedding Frequencies Detected at the Same Time in the Spanwise Direction of Wake behaind a Two-Dimensional Circular Cylinder） [PDF]

, 2002
It is known that the long time scale fluctuation about 20 times the vortex shedding periodicity exists in the irregularity of the vortex shedding from a two-dimensional circular cylinder. However it's origination is not known yet.

Discussion about the characteristics of flow in atmospheric airflow field using the complex function

Atmospheric and Oceanic Science Letters, 2018
Different levels of fluctuation occur when airflow passes over different terrain. It is important for weather and climate change, as well as aviation and glider safety, to study the motion of airflow. Based on conformal mapping and the complex potential,

A numerical study of an inline oscillating cylinder in a free stream [PDF]

, 2011
Simulations of a cylinder undergoing externally controlled sinusoidal oscillations in the free stream direction have been performed. The frequency of oscillation was kept equal to the vortex shedding frequency from a fixed cylinder, while the amplitude ...

Classical dynamics of vortex solitons from perturbative scattering amplitudes

Journal of High Energy Physics, 2023
We introduce a novel point-particle effective description of ANO vortex solitons in the critical Abelian Higgs Model (AHM) in d = 2 + 1 based on the small winding expansion.

The effect of convergent-divergent tube on the cooling capacity of vortex tube: An experimental and numerical study

Alexandria Engineering Journal, 2020
In this investigation, experimental and computational fluid dynamics (CFD) technique is used to study a newly designed Ranque-Hilsch vortex tube (RHVT), such as a convergent-divergent one.

Discrete-time Point Vortex Dynamics

Journal of Optimization, Differential Equations and Their Applications
The paper examines a difference equation, analogous to the Helmholtz equation, which describes the point vortex dynamics on a plane under control. The dependence of the asymptotic behaviour of the moment of vorticity of a system of point vortices on the ...
