Three-dimensional finite element analysis of MHD duct flow by the penalty function formulation
(Institute of Electrical and Electronics Engineers (IEEE), 2001-09-01)
A numerical scheme based on the Finite Element Method (FEM) is presented to calculate the full solution of a three-dimensional steady magnetohydrodynamic (MHD) flow with moderately high Hartmann numbers and interaction ...
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 ...
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 ...
EVOLUTION AND LIFETIME OF TRANSIENT CLUMPS IN THE TURBULENT INTERSTELLAR MEDIUM
(IOP PUBLISHING LTD, 2011)
We study the evolution of dense clumps and provide an argument that the existence of the clumps is not limited by their crossing times. We claim that the lifetimes of the clumps are determined by turbulent motions on a ...
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 ...
The application of interpolating MLS approximations to the analysis of MHD flows
(Elsevier B.V., 2003-09-01)
The element-free Galerkin method (EFGM) is a very attractive technique for solutions of partial differential equations, since it makes use of nodal point configurations which do not require a mesh. Therefore, it differs ...
Shear-driven Instabilities in Hall-Magnetohydrodynamic Plasmas
(IOP Publishing, 2011-07)
The large-scale dynamics of plasmas is well described within the framework of magnetohydrodynamics (MHD). However, whenever the ion density of the plasma becomes sufficiently low, the Hall effect is likely to become ...
Magnetohydrodynamic equilibria in barotropic stars
(2013)
Although barotropic matter does not constitute a realistic model for magnetic stars, it would be interesting
to con rm a recent conjecture that states that magnetized stars with a barotropic equation of state would ...
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 ...
