Wall modes in magnetoconvection at high Hartmann numbers [PDF]

open access: yesJournal of Fluid Mechanics, 2018
Three-dimensional turbulent magnetoconvection at a Rayleigh number of $Ra=10^{7}$ in liquid gallium at a Prandtl number $Pr=0.025$ is studied in a closed square cell for very strong external vertical magnetic fields $B_{0}$ in direct numerical simulations which apply the quasistatic approximation.

Hartmann duct flow at moderate magnetic Reynolds numbers [PDF]

open access: yesPAMM, 2016
AbstractThe application of a uniform external magnetic field on the turbulent duct flow of an electrically conducting fluid leads to several interesting changes in the structure and the mean charateristics of the flow. This is fairly well understood from the existing studies of duct flows in the low magnetic Reynolds number (Rm) limit.

A geostrophic-like model for large-Hartmann-number flows [PDF]

open access: yesJournal of Fluid Mechanics, 2004
A flow of electrically conducting fluid in the presence of a steady magnetic field has a tendency to become quasi-two-dimensional, i.e. uniform in the direction of the magnetic field, except in thin so-called Hartmann boundary layers. The condition for this tendency is that of a strong magnetic field, corresponding to large values of the dimensionless ...
