On the temporal decay for the Hall-magnetohydrodynamic equations [PDF]

open access: yesarXiv, 2013
We establish temporal decay estimates for weak solutions to the Hall-magnetohydrodynamic equations. With these estimates in hand we obtain algebraic time decay for higher order Sobolev norms of small initial data solutions.

Nonlinear closures for scale separation in supersonic magnetohydrodynamic turbulence

open access: yesNew Journal of Physics, 2015
Turbulence in compressible plasma plays a key role in many areas of astrophysics and engineering. The extreme plasma parameters in these environments, e.g.

Well-Posedness for a Magnetohydrodynamical Model with Intrinsic Magnetisation [PDF]

open access: yesarXiv
Ferromagnetic magnetohydrodynamics concerns the study of conducting fluids with intrinsic magnetisation under the influence of a magnetic field. It is a generalisation of the magnetohydrodynamical equations and takes into account the dynamics of the magnetisation of a fluid.

A regularity criterion for the 3D full compressible magnetohydrodynamic equations with zero heat conductivity [PDF]

open access: yesarXiv, 2016
We establish a regularity criterion for the 3D full compressible magnetohydrodynamic equations with zero heat conductivity and vacuum in a bounded domain.

Analytic current-vortex sheets in incompressible magnetohydrodynamics [PDF]

open access: yesarXiv, 2016
In this paper, we address the problem of current-vortex sheets in ideal incompressible magnetohydrodynamics. More precisely, we prove a local-in-time existence and uniqueness result for analytic initial data using a Cauchy-Kowalevskaya theorem.

Finite-time singularities and flow regularization in a hydromagnetic shell model at extreme magnetic Prandtl numbers

open access: yesNew Journal of Physics, 2015
Conventional surveys on the existence of singularities in fluid systems for vanishing dissipation have hitherto tried to infer some insight by searching for spatial features developing in asymptotic regimes.
