Plasmoid identification and statistics in two-dimensional Harris sheet and GRMHD simulations

, 2023
Magnetic reconnection is a ubiquitous phenomenon for magnetized plasmas and leads to the rapid reconfiguration of magnetic field lines. During reconnection events, plasma is heated and accelerated until the magnetic field lines enclose and capture the ...

The Yin–Yang Magnetic Flux Eruption (Yin–Yang MFE) Code: A Global Corona Magnetohydrodynamic Code with the Yin–Yang Grid

The Astrophysical Journal Supplement Series
We describe the numerical algorithms of a global magnetohydrodynamic (MHD) code utilizing the Yin–Yang grid, called the Yin–Yang Magnetic Flux Eruption code, suitable for modeling the large-scale dynamical processes of the solar corona and the solar wind.

The Impact of Cosmic Ray Injection on Magnetic Flux Tubes in a Galactic Disk

The Astrophysical Journal, 2023
In a seminal paper, Parker showed the vertical stratification of the interstellar medium (ISM) is unstable if magnetic fields and cosmic rays provide too large a fraction of pressure support. Cosmic ray acceleration is linked to star formation, so Parker’

Magnetic Electrocatalysts Enabling a High‐Rate Capability in Lithium‐Oxygen Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study introduces zinc ferrite (ZnFe2O4) nanoparticles with tunable magnetic properties as bifunctional electrocatalysts for lithium‐oxygen batteries. Under an applied magnetic field, these catalysts significantly enhance oxygen reduction and evolution reactions by promoting spin‐aligned charge transfer and ion diffusion. The approach achieves high

A new framework for magnetohydrodynamic simulations with anisotropic pressure [PDF]

Journal of Computational Physics, 2016
We describe a new theoretical and numerical framework of the magnetohydrodynamic simulation incorporated with an anisotropic pressure tensor, which can play an important role in a collisionless plasma. A classical approach to handle the anisotropy is based on the double adiabatic approximation assuming that a pressure tensor is well described only by ...

Fast Calculation for the Flow and Heat Transfer of Tempered Fractional Maxwell Viscoelastic Fluid

International Journal for Numerical Methods in Fluids, EarlyView.
This study develops a tempered fractional Maxwell model to simulate unsteady thermal flow in viscoelastic fluids, capturing key rheological behaviors. A fast SOE‐based algorithm is proposed to improve the computational efficiency of the numerical scheme. Results reveal how key parameters influence fluid motion and heat transfer, demonstrating the model'
