Clebsch gauge fluid

S Yang, S **ong, Y Zhang, F Feng, J Liu… - ACM Transactions on …, 2021 - dl.acm.org
We propose a novel gauge fluid solver based on Clebsch wave functions to solve
incompressible fluid equations. Our method combines the expressive power of Clebsch …

[HTML][HTML] Plasma knots

O Gross, U Pinkall, P Schröder - Physics Letters A, 2023 - Elsevier
We present a Lagrangian method for the computation of ideal plasma knots and links. It is
based on a variational principle for stable equilibria of an ideal plasma in the case of a free …

Effects of twist on the evolution of knotted magnetic flux tubes

S **ong, Y Yang - Journal of Fluid Mechanics, 2020 - cambridge.org
We develop a general method for constructing knotted flux tubes with finite thickness,
arbitrary shape and tunable twist. The central axis of the knotted tube is specified by a …

Magnetohydrodynamic relaxation theory

AR Yeates - Topics in Magnetohydrodynamic Topology …, 2019 - Springer
This chapter is concerned with the magnetic relaxation problem, in which an electrically
conducting fluid is initialised in some non-trivial state, and is subsequently allowed to relax …

Topology-preserving discretization for the magneto-frictional equations arising in the Parker conjecture

M He, PE Farrell, K Hu, BD Andrews - arxiv preprint arxiv:2501.11654, 2025 - arxiv.org
The Parker conjecture, which explores whether magnetic fields in perfectly conducting
plasmas can develop tangential discontinuities during magnetic relaxation, remains an open …

Force-Free Fields Are Conformally Geodesic

A Chern, O Gross - SIAM Journal on Applied Algebra and Geometry, 2024 - SIAM
In this paper, we establish an equivalence between force-free fields and conformally
geodesic fields, and between harmonic fields and conformally eikonal fields. In contrast to …

[KNIHA][B] Variational integration for ideal magnetohydrodynamics and formation of current singularities

Y Zhou - 2017 - search.proquest.com
Coronal heating has been a long-standing conundrum in solar physics. Parker's conjecture
that spontaneous current singularities lead to nanoflares that heat the corona has been …

Resistive evolution of toroidal field distributions and their relation to magnetic clouds

CB Smiet, HJ de Blank, TA de Jong… - Journal of Plasma …, 2019 - cambridge.org
We study the resistive evolution of a localized self-organizing magnetohydrodynamic
equilibrium. In this configuration the magnetic forces are balanced by a pressure force …

Learning and Simulation Algorithms for Constraint Physical Systems

S Yang - 2021 - search.proquest.com
This thesis explores two computational approaches to learn and simulate complex physical
systems exhibiting constraint characteristics. The target applications encompass both solids …
