Emergence of intermittent structures and reconnection in MHD turbulence
(CUP, 2010-09)
In recent analyses of numerical simulation and solar wind dataset, the idea that the magnetic discontinuities may be related to intermittent structures that appear spontaneously in MHD turbulence has been explored in ...
Statistical analysis of discontinuities in solar wind ace data and comparison with intermittent mhd turbulence
(IOP Publishing, 2009-12)
The comparison between Advanced Composition Explorer (ACE) solar wind data and simulations of magnetohydrodynamic (MHD) turbulence shows a good agreement in the waiting-time analysis of magnetic field increments. Similarity ...
Self-organized criticality in MHD driven plasma edge turbulence
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
We analyze long-range time correlations and self-similar characteristics of the electrostatic turbulence at the plasma edge and scrape-off layer in the Tokamak Chauffage Alfven Bresillien (TCABR), with low and high ...
Test Particle Energization and the Anisotropic Effects of Dynamical MHD Turbulence
(IOP Publishing, 2017-11)
In this paper, we analyze the effect of dynamical three-dimensional magnetohydrodynamic (MHD) turbulence on test particle acceleration and compare how this evolving system affects particle energization by current sheet ...
The dynamics of unforced turbulence at high reynolds number for taylor-green vortices generalized to mhd
(Taylor & Francis Ltd, 2010-04)
We study decaying magnetohydrodynamics (MHD) turbulence stemming from the evolution of the Taylor-Green flow generalized recently to MHD, with equal viscosity and magnetic resistivity and up to equivalent grid resolutions ...
Intermittent MHD structures and classical discontinuities
(American Geophysical Union, 2008-12)
We examine statistics of rapid spatial variations of the magnetic field in simulations of magnetohydrodynamic (MHD) turbulence, by analyzing intermittency properties. and by using classical methods for identifying ...
Reduced MHD in Astrophysical Applications: Two-dimensional or Three-dimensional?
(IOP Publishing, 2017-04)
Originally proposed as an efficient approach to computation of nonlinear dynamics in tokamak fusion research devices, reduced magnetohydrodynamics (RMHD) has subsequently found application in studies of coronal heating, ...
Depression of nonlinearity in decaying isotropic MHD turbulence
(American Physical Society, 2008-03)
Spectral method simulations show that undriven magnetohydrodynamic turbulence spontaneously generates coherent spatial correlations of several types, associated with local Beltrami fields, directional alignment of velocity ...
Magnetic field amplification and evolution in turbulent collisionless magnetohydrodynamics: an application to the intracluster medium
(American Astronomical SocietyChicago, 2014)
The amplification of magnetic fields (MFs) in the intracluster medium (ICM) is attributed to turbulent dynamo
(TD) action, which is generally derived in the collisional-MHD framework. However, this assumption is ...
Intermittent structures and magnetic discontinuities on small scales in MHD simulations and solar wind
(Pergamon-Elsevier Science Ltd, 2010-12)
In this work we review some recent studies, in which properties of the magnetic field in high resolution simulations of MHD turbulence with spacecraft data are compared, focusing on methods used to identify classical ...
