The sensitivity of the vortex filament method to different reconnection models

open access: yes, 2011
We present a detailed analysis on the effect of using different algorithms to model the reconnection of vortices in quantum turbulence, using the thin-filament approach.

Velocity, energy and helicity of vortex knots and unknots

open access: yes, 2010
In this paper we determine the velocity, the energy and estimate writhe and twist helicity contributions of vortex filaments in the shape of torus knots and unknots (toroidal and poloidal coils) in a perfect fluid. Calculations are performed by numerical

On the striated regularity for the 2D anisotropic Boussinesq system [PDF]

open access: yes, 2019
In this paper, we investigate the global existence and uniqueness of strong solutions to 2D Boussinesq system with anisotropic thermal diffusion or anisotropic viscosity and with striated initial data.

Trkalian fields and Radon transformation

open access: yes, 2010
We write the spherical curl transformation for Trkalian fields using differential forms. Then we consider Radon transform of these fields. The Radon transform of a Trkalian field satisfies a corresponding eigenvalue equation on a sphere in transform ...

On spatially-averaged electrokinetics of point charges and Maxwell's equations [PDF]

open access: yes, 2017
Maxwell-like field relations which describe spatially-averaged kinematic behaviour of electrons and atomic nuclei (modelled as point charges) are obtained at any prescribed scale using weighting function methodology.

Development of Smartphone e-Modul by Problem Solving Method for Biot-Savart Theory

open access: yes, 2017
Biot-Savart law is an equation that describes the magnetic field created by a current-carrying wire and allows you to calculate its strength at various points.

Design of a test for the electromagnetic coupling of non-local wavefunctions

open access: yes, 2019
It has recently been proven that certain effective wavefunctions in fractional quantum mechanics and condensed matter do not have a locally conserved current; as a consequence, their coupling to the electromagnetic field leads to extended Maxwell ...

Helicity within the vortex filament model [PDF]

open access: yes, 2016
Kinetic helicity is one of the invariants of the Euler equations that is associated with the topology of vortex lines within the fluid. In superfluids, the vorticity is concentrated along vortex filaments.

Reconnections of Vortex Loops in the Superfluid Turbulent HeII. Rates of the Breakdown and Fusion processes

open access: yes, 2005
Kinetics of merging and breaking down vortex loops is the important part of the whole vortex tangle dynamics. Another part is the motion of individual lines, which obeys the Biot-Savart law in presence of friction force and of applied external velocity ...

On the long time behavior of stochastic vortices systems [PDF]

open access: yes, 2013
In this paper, we are interested in the long-time behaviour of stochastic systems of n interacting vortices: the position in R2 of each vortex evolves according to a Brownian motion and a drift summing the influences of the other vortices computed ...
