Transition to Equilibrium and Coherent Structure in Ideal MHD Turbulence, Part 2

Fluids, 2023
We continue our study of the transition of ideal, homogeneous, incompressible, magnetohydrodynamic (MHD) turbulence from non-equilibrium initial conditions to equilibrium using long-time numerical simulations on a 1283 periodic grid.

First Principles Description of Plasma Expansion Using the Expanding Box Model

Universe, 2023
Multi-scale modeling of expanding plasmas is crucial for understanding the dynamics and evolution of various astrophysical plasma systems such as the solar and stellar winds. In this context, the Expanding Box Model (EBM) provides a valuable framework to

Finite-time singularity formation at a magnetic neutral line in Hall magnetohydrodynamics [PDF]

, 2015
The formation of a current sheet in a weakly collisional plasma can be modelled as a finite-time singularity solution of magnetohydrodynamic equations.

Lax representations for the magnetohydrodynamics equations [PDF]

, 2023
We find Lax representations and derive special B{\"a}cklund transformations for the reduced magnetohydrodynamics equations and the ideal magnetohydrodynamics ...

Anisotropic three-dimensional MHD turbulence [PDF]

, 1996
Direct spectral method simulation of the three-dimensional magnetohydrodynamics (MHD) equations is used to explore anisotropy that develops from initially isotropic fluctuations as a consequence of a uniform applied magnetic field.

One-form superfluids & magnetohydrodynamics

Journal of High Energy Physics, 2020
We use the framework of generalised global symmetries to study various hydrodynamic regimes of hot electromagnetism. We formulate the hydrodynamic theories with an unbroken or a spontaneously broken U(1) one-form symmetry. The latter of these describes a

Properties of mass-loading shocks, 2. Magnetohydrodynamics [PDF]

, 1992
The one-dimensional magnetohydrodynamics of shocked flows subjected to significant mass loading are considered. Recent observations at comets Giacobini-Zinner and Halley suggest that simple nonreacting MHD is an inappropriate description for active ...

Experimental, numerical and analytical evaluation of -thrust for fast-liquid-metal-flow divertor systems of nuclear fusion devices

Nuclear Fusion, 2023
Divertor systems of fusion devices are exposed to intense heat loads from plasmas, which degrade solid plasma-facing components. Fast liquid metal (LM) flow divertors may be more advantageous for this purpose but have risk of piling due to intense ...
