Vertical structure of buoyancy transport by ocean baroclinic turbulence
Julie Meunier, Benjamin Miquel, Basile Gallet
Ocean mesoscale eddies enhance meridional buoyancy transport, notably in the Antarctic Circumpolar Current where they contribute to setting the deep stratification of the neighbori…
A direct derivation of the Gent-McWilliams/Redi diffusion tensor from quasi-geostrophic dynamics
Julie Meunier, Benjamin Miquel, Basile Gallet
The transport induced by ocean mesoscale eddies remains unresolved in most state-of-the-art climate models and needs to be parameterized instead. The natural scale separation betwe…
Velocity-informed upper bounds on the convective heat transport induced by internal heat sources and sinks
Vincent Bouillaut, Benoît Flesselles, Benjamin Miquel +2
Three-dimensional convection driven by internal heat sources and sinks (CISS) leads to experimental and numerical scaling-laws compatible with a mixing-length - or `ultimate' - sca…
Experimental observation of the geostrophic turbulence regime of rapidly rotating convection
Vincent Bouillaut, Benjamin Miquel, Keith Julien +2
The competition between turbulent convection and global rotation in planetary and stellar interiors governs the transport of heat and tracers, as well as magnetic-field generation.…
Transport and emergent stratification in the equilibrated Eady model: the vortex gas scaling regime
Basile Gallet, Benjamin Miquel, Gabriel Hadjerci +3
We numerically and theoretically investigate the Boussinesq Eady model, where a rapidly rotating density-stratified layer of fluid is subject to a meridional temperature gradient i…
Convection driven by internal heat sources and sinks: heat transport beyond the mixing-length or "ultimate" scaling regime
B. Miquel, S. Lepot, V. Bouillaut +1
Thermal convection driven by internal heat sources and sinks was recently shown experimentally to exhibit the mixing-length, or "ultimate", scaling-regime: the Nusselt number …
On the role of the Prandtl number in convection driven by heat sources and sinks
Benjamin Miquel, Vincent Bouillaut, Sebastien Aumaitre +1
We report on a numerical study of turbulent convection driven by a combination of internal heat sources and sinks. Motivated by a recent experimental realisation (Lepot et al. 2018…
Hybrid Chebyshev function bases for sparse spectral methods in parity-mixed PDEs on an infinite domain
Benjamin Miquel, Keith Julien
We present a numerical spectral method to solve systems of differential equations on an infinite interval in presence of linear differential operators of t…
A reduced model for salt-finger convection in the small diffusivity ratio limit
Jin-Han Xie, Benjamin Miquel, Keith Julien +1
A simple model of nonlinear salt-finger convection in two dimensions is derived and studied. The model is valid in the limit of small solute to heat diffusivity ratio and large den…
