Experimental study of the convection in a thin cylindrical gas layer with imposed bottom and top fluxes and imposed side temperature
Florian Rein, Laure Carénini, Florian Fichot +2
We investigate convection in a thin cylindrical gas layer with an imposed flux at the bottom and a fixed temperature along the side, using a combination of direct numerical simulat…
Coupled convection and internal gravity waves excited in water around its density maximum at 4°C
Pierre Léard, Benjamin Favier, Patrice Le Gal +1
Coupled mixed convective and stratified systems are common in natural flows. To study experimentally the associated dynamics, we use a singular property of water: its non-linear eq…
Multi-modal excitation to model the Quasi-Biennial Oscillation
Pierre Léard, Daniel Lecoanet, Michael Le Bars
The Quasi-Biennial Oscillation (QBO) of stratospheric winds is the most striking example of mean-flow generation and reversal by the non-linear interactions of internal waves. Prev…
Dynamics of a reactive spherical particle falling in a linearly stratified fluid
Ludovic Huguet, Victor Barge-Zwick, Michael Le Bars
Motivated by numerous geophysical applications, we have carried out laboratory experiments of a reactive (i.e. melting) solid sphere freely falling by gravity in a stratified envir…
Low-frequency variability in massive stars: Core generation or surface phenomenon?
Daniel Lecoanet, Matteo Cantiello, Eliot Quataert +6
Bowman et al. (2019) reported low-frequency photometric variability in 164 O- and B-type stars observed with K2 and TESS. They interpret these motions as internal gravity waves, wh…
Rotational dynamics of planetary cores: instabilities driven by precession, libration and tides
Thomas Le Reun, Michael Le Bars
In this chapter, we explore how gravitational interactions drive turbulent flows inside planetary cores and provide an interesting alternative to convection to explain dynamo actio…
