Dynamo action in sliding plates of anisotropic electrical conductivity
Thierry Alboussiere, Kamel Drif, Franck Plunian
With materials of anisotropic electrical conductivity, it is possible to generate a dynamo with a simple velocity field, of the type precluded by Cowling's theorems with isotropic…
Thermal convection in Earth's inner core with phase change at its boundary
Renaud Deguen, Thierry Alboussière, Philippe Cardin
Inner core translation, with solidification on one hemisphere and melting on the other, provides a promising basis for understanding the hemispherical dichotomy of the inner core,…
Melting-induced stratification above the Earth's inner core due to convective translation
Thierry Alboussiere, Renaud Deguen, Mickael Melzani
In addition to its global North-South anisotropy(1), there are two other enigmatic seismological observations related to the Earth's inner core: asymmetry between its eastern and w…
Zonal shear and super-rotation in a magnetized spherical Couette flow experiment
Daniel Brito, Thierry Alboussière, Philippe Cardin +6
We present measurements performed in a spherical shell filled with liquid sodium, where a 74 mm-radius inner sphere is rotated while a 210 mm-radius outer sphere is at rest. The in…
On the existence and structure of a mush at the inner core boundary of the Earth
Renaud Deguen, Thierry Alboussière, Daniel Brito
It has been suggested about 20 years ago that the liquid close to the inner core boundary (ICB) is supercooled and that a sizable mushy layer has developed during the growth of the…
Rapidly rotating spherical Couette flow in a dipolar magnetic field: an experimental study of the mean axisymmetric flow
Henri-Claude Nataf, Thierry Alboussiere, Daniel Brito +4
In order to explore the magnetostrophic regime expected for planetary cores, experiments have been conducted in a rotating sphere filled with liquid sodium, with an imposed dipolar…
