Parallel Simulations in Turbulent MHD

open access: yesPhysica Scripta, 2005
The large-scale dynamics of plasma flows can often be described within a fluidistic approximation known as onefluid magnetohydrodynamics. Complex flows such as those corresponding to turbulent regimes are ubiquitous in laboratory plasmas and in astrophysics, because of their typically very large Reynolds numbers.

MHD Simulation of Prominence Eruption [PDF]

open access: yesThe Astrophysical Journal, 2018
Abstract We carry out magnetohydrodynamic (MHD) simulations of the quasi-static evolution and eruption of a twisted coronal flux rope under a coronal streamer built up by an imposed flux emergence at the lower boundary. The MHD model incorporates simple empirical coronal heating, optically thin radiative cooling, and field-aligned ...

Multiscaling in Models of Magnetohydrodynamic Turbulence [PDF]

open access: yes, 1997
From a direct numerical simulation of the MHD equations we show, for the first time, that velocity and magnetic-field structure functions exhibit multiscaling, extended self similarity (ESS), and generalized extended self similarity (GESS).

An MHD gadget for cosmological simulations [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2009
Various radio observations have showed that the hot atmospheres of galaxy clusters are magnetized. However, our understanding of the origin of these magnetic fields, their implications on structure formation and their interplay with the dynamics of the cluster atmosphere, especially in the centers of galaxy clusters is still very limited.

Anisotropic three-dimensional MHD turbulence [PDF]

open access: yes, 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.

High-Resolution Simulations of Nonhelical MHD Turbulence [PDF]

open access: yesAstrophysics and Space Science, 2004
According to the kinematic theory of nonhelical dynamo action the magnetic energy spectrum increases with wavenumber and peaks at the resistive cutoff wavenumber. It has previously been argued that even in the dynamical case the magnetic energy peaks at the resistive scale. Using high resolution simulations (up to 1024^3 meshpoints) with no large scale

Theoretical and Experimental Study of Radial Velocity Generation for Extending Bandwidth of Magnetohydrodynamic Angular Rate Sensor at Low Frequency

open access: yesSensors, 2015
The magnetohydrodynamics angular rate sensor (MHD ARS) has received much attention for its ultra-low noise in ultra-broad bandwidth and its impact resistance in harsh environments; however, its poor performance at low frequency hinders its work in long ...

Interaction Between Coronal Mass Ejection "CMEs" and Jupiter Magnetosphere by Numerical Simulation Using MHD Models [PDF]

open access: yesKirkuk Journal of Science, 2017
The present study deals with the interaction between the magnetic field of Jupiter and ones of the Coronal Mass Ejections (CMEs) for three years (2011-2013) which includes the peak of Solar cycle 24.

Turbulence Analysis Of An Experimental Flux-Rope Plasma [PDF]

open access: yes, 2014
We have previously generated elongated Taylor double-helix flux-rope plasmas in the SSX MHD wind tunnel. These plasmas are remarkable in their rapid relaxation (about one Alfven time) and their description by simple analytical Taylor force-free theory ...

Numerical Study of Divergence Cleaning and Coronal Heating/Acceleration Methods in the 3D COIN-TVD MHD Model

open access: yesFrontiers in Physics, 2021
In the solar coronal numerical simulation, the coronal heating/acceleration and the magnetic divergence cleaning techniques are very important. The coronal–interplanetary total variation diminishing (COIN-TVD) magnetohydrodynamic (MHD) model is developed
