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…
Low frequency spectra of bending wave turbulence
Benjamin Miquel, Antoine Naert, Sébastien Aumaître
We study experimentally the dynamics of long waves among turbulent bending waves in a thin elastic plate set into vibration by a monochromatic forcing at a frequency . This fr…
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…
Elastic Weak Turbulence: from the vibrating plate to the drum
Roumaissa Hassain, Nicolas Mordant, Benjamin Miquel +2
Weak wave turbulence has been observed on a thin elastic plate in previous work. Here we report theoretical, experimental and numerical studies of wave turbulence in a thin elastic…
Intermittency and emergence of coherent structures in wave turbulence of a vibrating plate
Nicolas Mordant, Benjamin Miquel
We report numerical investigations of wave turbulence in a vibrating plate. The possibility to implement advanced measurement techniques and long time numerical simulations makes t…
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…
Wave turbulence buildup in a vibrating plate
Maria Ines Auliel, Benjamin Miquel, Nicolas Mordant
We report experimental and numerical results on the buildup of the energy spectrum in wave turbulence of a vibrating thin elastic plate. Three steps are observed: first a short lin…
The role of dissipation in flexural wave turbulence: from experimental spectrum to Kolmogorov-Zakharov spectrum
Benjamin Miquel, Alexandros Alexakis, Nicolas Mordant
The Weak Turbulence Theory has been applied to waves in thin elastic plates obeying the Föppl-Von Kármán dynamical equations. Subsequent experiments have shown a strong discrepancy…
Transition from wave turbulence to dynamical crumpling in vibrated elastic plates
Benjamin Miquel, Alexandros Alexakis, Christophe Josserand +1
We study the dynamical regime of wave turbulence of a vibrated thin elastic plate based on experimental and numerical observations. We focus our study to the strongly non linear re…
Nonlinear dynamics of flexural wave turbulence
Benjamin Miquel, Nicolas Mordant
The Kolmogorov-Zakharov spectrum predicted by the Weak Turbulence Theory remains elusive for wave turbulence of flexural waves at the surface of an thin elastic plate. We report a…
Non stationary wave turbulence in an elastic plate
Benjamin Miquel, Nicolas Mordant
We report experimental results on the decay of wave turbulence in an elastic plate obtained by stopping the forcing from a stationary turbulent state. In the stationary case, the f…
