Impact of Hall effect on energy decay in magnetohydrodynamic turbulence [PDF]

, 2003
We examine numerically the influence of Hall effect corrections to Ohm's law upon the decay of homogeneous compressible magnetohydrodynamic turbulence and conclude that there are no significant differences in global decay rate associated with the Hall ...

Identification of Kelvin-Helmholtz generated vortices in magnetised fluids

Frontiers in Astronomy and Space Sciences
The Kelvin-Helmholtz Instability (KHI), arising from velocity shear across the magnetopause, plays a significant role in the viscous-like transfer of mass, momentum, and energy from the shocked solar wind into the magnetosphere.

A Comparative Study of Low‐Dissipation Numerical Schemes for Hyperbolic Conservation Laws

Numerical Methods for Partial Differential Equations, Volume 42, Issue 5, September 2026.
ABSTRACT This work provides a comparative assessment of several low‐dissipation numerical schemes for hyperbolic conservation laws, highlighting their performance relative to the classical Harten‐Lax‐van Leer (HLL) schemes. The schemes under consideration include the classical Harten‐Lax‐van Leer‐Contact (HLLC), the recently proposed TV flux splitting,

Modulating Hierarchical Microstructure to Enhance Strength–Ductility Synergy in an Additively Manufactured Zinc‐Magnesium Alloy via Static Magnetic Field

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Additive manufacturing of zinc‐magnesium (Zn‐Mg) alloys via laser powder bed fusion (LPBF) has gained significant recognition as a promising candidate for bone repair. However, the presence of coarse yet brittle eutectic phases in the fabricated Zn‐Mg alloys tends to induce premature stress concentration and resultant fracture during ...

Time‐Efficient Columnar‐to‐Equiaxed Transition via High Magnetic Field Processing

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT The need to simplify processing routes and improve processing efficiency motivates the development of time‐efficient methods for inducing the columnar‐to‐equiaxed transition (CET) during solidification while tailoring material performance. Conventional multistep CET approaches are time‐consuming and often struggle to simultaneously regulate ...

A NEW LAGRANGIAN FORMULATION OF IDEAL MAGNETOHYDRODYNAMICS

, 2011
We propose a reformulation of ideal magnetohydrodynamics written in the Lagrangian variable as an enlarged system of hyperelastic type, with a specific potential. We study the hyperbolicity of the model and prove that the acoustic tensor is positive for
