Static plasma confinement by harmonic magnetic fields

Exploring various flux vector splittings for the magneto hydrodynamic system
In this paper we explore flux vector splittings for the MHD system of equations. Our approach follows the strategy that was initially put forward in Toro and Vazquez-Cendon (2012) . We split the flux vector into an ...
A turbulence-driven model for heating and acceleration of the fast wind in coronal holes
(Institute of Physics Publishing, 2010-01)
A model is presented for generation of fast solar wind in coronal holes, relying on heating that is dominated by turbulent dissipation of MHD fluctuations transported upward in the solar atmosphere. Scale-separated transport ...
Direct numerical simulations of helical dynamo action: MHD and beyond
(Copernicus Publications, 2004-12)
Magnetohydrodynamic dynamo action is often invoked to explain the existence of magnetic fields in several astronomical objects. In this work, we present direct numerical simulations of MHD helical dynamos, to study the ...
Influence of the Hall effect and electron inertia in collisionless magnetic reconnection
(American Institute of Physics, 2016-03)
We study the role of the Hall current and electron inertia in collisionless magnetic reconnection within the framework of full two-fluid MHD. At spatial scales smaller than the electron inertial length, a topological change ...
Hall effect in a strong magnetic field: Direct comparisons of compressible magnetohydrodynamics and the reduced Hall magnetohydrodynamic equations
(American Institute of Physics, 2010-11)
In this work we numerically test a model of Hall magnetohydrodynamics in the presence of a strong mean magnetic field: the reduced Hall magnetohydrodynamic model RHMHD derived by Gomez et al., Phys. Plasmas 15, 102303 2008 ...
The effect of subfilter-scale physics on regularization models
(Springer/Plenum Publishers, 2011-09)
The subfilter-scale (SFS) physics of regularization models are investigated to understand the regularizations' performance as SFS models. Suppression of spectrally local SFS interactions and conservation of small-scale ...
THE ROLE OF TURBULENT MAGNETIC RECONNECTION IN THE FORMATION OF ROTATIONALLY SUPPORTED PROTOSTELLAR DISKS
(IOP PUBLISHING LTDBRISTOL, 2012)
The formation of protostellar disks out of molecular cloud cores is still not fully understood. Under ideal MHD conditions, the removal of angular momentum from the disk progenitor by the typically embedded magnetic field ...
