Convective regimes of internally heated steady thermal convection of temperature-dependent viscous fluid
Hisashi Okuda, Shin-ichi Takehiro, Stéphane Labrosse
We study dynamical regimes of thermal convection with temperature-dependent viscosity driven by homogeneous internal heating. Two-dimensional steady-state convective solutions with…
Velocity field and cavity dynamics in drop impact experiments
Victor Lherm, Renaud Deguen
Drop impact experiments allow the modelling of a wide variety of natural processes, from raindrop impacts to planetary impact craters. In particular, interpreting the consequences…
How dirt cones form on glaciers: field observation, laboratory experiments and modeling
Marceau Hénot, Vincent J. Langlois, Nicolas Plihon +1
Dirt cones are meter-scale structures encountered at the surface of glaciers, which consist of ice cones covered by a thin layer of ashes, sand or gravel, and which form naturally…
A playground for compressible natural convection with a nearly uniform density
Thierry Alboussiere, Jezabel Curbelo, Fabien Dubuffet +2
In the quest to understand the basic universal features of compressible convection, one would like to disentangle genuine consequences of compression from spatial variations of tra…
Fast and Furious dynamo action in the anisotropic dynamo
Franck Plunian, Thierry Alboussière
In the limit of large magnetic Reynolds numbers, it is shown that a smooth differential rotation can lead to fast dynamo action, provided that the electrical conductivity or magnet…
Axisymmetric dynamo action is possible with anisotropic conductivity
Franck Plunian, Thierry Alboussière
A milestone of dynamo theory is Cowling's theorem, known in its modern form as the impossibility for an axisymmetric velocity field to generate an axisymmetric magnetic field by dy…
Experimental study of convection in the compressible regime
Rémi Menaut, Yoann Corre, Ludovic Huguet +6
An experiment of thermal convection with significant compressible effects is presented. The high-gravity environment of a centrifuge and the choice of xenon gas enable us to observ…
Rayleigh-Bénard convection in a creeping solid with melting and freezing at either or both its horizontal boundaries
Stéphane Labrosse, Adrien Morison, Renaud Deguen +1
Solid state convection can take place in the rocky or icy mantles of planetary objects and these mantles can be surrounded above or below or both by molten layers of similar compos…
Rayleigh-Benard stability and the validity of quasi-Boussinesq or quasi-anelastic liquid approximations
Thierry Alboussiere, Yanick Ricard
The linear stability threshold of the Rayleigh-Benard configuration is analyzed with compressible effects taken into account. It is assumed that the fluid obeys a Newtonian rheolog…
Experiments on the fragmentation of a buoyant liquid volume in another liquid
Maylis Landeau, Renaud Deguen, Peter Olson
We present experiments on the instability and fragmentation of volumes of heavier liquid released into lighter immiscible liquids. We focus on the regime defined by small Ohnesorge…
Reflections on dissipation associated with thermal convection
Thierry Alboussiere, Yanick Ricard
This paper was originally published in June 2013 in JFM (vol. 725). There was one result concerning an expression of viscous dissipation in convective flows and a second result on…
Experimental evidence of Alfvén wave propagation in a Gallium alloy
Thierry Alboussiere, Philippe Cardin, François Debray +5
Experiments with a liquid metal alloy, galinstan, are reported and show clear evidence of Alfvén wave propagation as well as resonance of Alfvén modes. Galinstan is liquid at room…
