Hydrodynamic and magnetohydrodynamic simulations of wire turbulence [PDF]

open access: yesHigh Energy Density Physics, 2019
We report on simulations of laboratory experiments in which magnetized supersonic flows are driven through a wire mesh. The goal of the study was to investigate the ability of such a configuration to generate supersonic, MHD turbulence. We first report on the morphological structures that develop in both magnetized and non-magnetized cases.

Boundary Treatment for the Subsonic/Alfvénic Inner Boundary at 2.5 R ⊙ in a Time-dependent 3D Magnetohydrodynamics Solar Wind Simulation Model

open access: yesThe Astrophysical Journal Supplement Series, 2023
A new magnetohydrodynamics (MHD) simulation model of the global solar corona and solar wind is presented. The model covers the range of heliocentric distance from 2.5 solar radii, so that coronal mass ejections at the earliest phase near the Sun can be ...

Three‐dimensional Magnetohydrodynamic Simulations of Spherical Accretion [PDF]

open access: yesThe Astrophysical Journal, 2002
We present three-dimensional numerical magnetohydrodynamic simulations of radiatively inefficient spherical accretion onto a black hole. The simulations are initialized with a Bondi flow, and with a weak, dynamically unimportant, large-scale magnetic field. The magnetic field is amplified as the gas flows in.

A New Tool for Understanding the Solar Wind–Venus Interaction: Three-dimensional Multifluid MHD Model

open access: yesThe Astrophysical Journal, 2023
In this paper, we present a new tool to investigate the interaction of the solar wind with Venus with the approach of a global multifluid magnetohydrodynamics (MHD) model. The continuity, momentum, and energy equations for H ^+ , O ^+ , ${{\rm{O}}}_{2}^{+

Solar Wind and its Evolution [PDF]

open access: yes, 2011
By using our previous results of magnetohydrodynamical simulations for the solar wind from open flux tubes, I discuss how the solar wind in the past is different from the current solar wind.

TWO-DIMENSIONAL MAGNETOHYDRODYNAMIC SIMULATIONS OF BARRED GALAXIES [PDF]

open access: yesThe Astrophysical Journal, 2012
Barred galaxies are known to possess magnetic fields that may affect the properties of bar substructures such as dust lanes and nuclear rings. We use two-dimensional high-resolution magnetohydrodynamic (MHD) simulations to investigate the effects of magnetic fields on the formation and evolution of such substructures as well as on the mass inflow rates

Tracing large-scale structures in circumstellar disks with ALMA

open access: yes, 2012
Planets are supposed to form in circumstellar disks. The gravitational potential of a planet perturbs the disk and leads to characteristic structures, i.e. spiral waves and gaps, in the disk's density profile.

RESISTIVE MAGNETOHYDRODYNAMICS SIMULATIONS OF THE IDEAL TEARING MODE [PDF]

open access: yesThe Astrophysical Journal, 2015
We study the linear and nonlinear evolution of the tearing instability on thin current sheets by means of two-dimensional numerical simulations, within the framework of compressible, resistive magnetohydrodynamics. In particular we analyze the behavior of current sheets whose inverse aspect ratio scales with the Lundquist number $S$ as $S^{-1/3}$. This

Search for Stable Magnetohydrodynamic Equilibria in Barotropic Stars [PDF]

open access: yes, 2013
It is now believed that magnetohydrodynamic equilibria can exist in stably stratified stars due to the seminal works of Braithwaite & Spruit (2004) and Braithwaite & Nordlund (2006).
