Les suspensions denses de particules solides immergées dans un fluide se retrouvent dans de nombreux phénomènes naturels tels que le transport de sédiment ou les coulées de débris et de nombreuses (...)

The Reykjanes ridge is situated between the Irminger basin and the Iceland basin, at the intersection of different flows determining the global ocean circulation. The flow coming from the Faroe (...)

As surface gravity waves propagate from deeper waters to the shore, their shape changes, primarily due to nonlinear wave interactions and further on due to breaking. The nonlinear effects amplify (...)

The sheet flow regime of sediment transport occurs when the shear stress exerted by the fluid flow on the sediment bed is high enough to set in motion a thick layer of particles. This phenomenon (...)

Laser Induced Fluorescence to measure temperature in natural convective flows
Résumé :
La Fluorescence Induite par Laser (LIF) permet d’avoir accès, de manière quantitative et non-intrusive, à (...)

Abstract :
In order to better understand the dominant physical mechanisms in intense bed-load transport (sheet flow) and the effect of the mobile layer on the turbulence (damping in the dense (...)

The aim of our experiment is to examine the impact of the Coriolis force on the drainage of a tank. We use a circular tank 2 m in diameter and a draining hole in the center. In 1856 Perrot talked (...)

En collaboration avec Evgeny Ermanyuk, Jan-Bert Flór & Natalia Shmakova
Parmi les phénomènes susceptibles de provoquer localement une intensification de l’amplitude des ondes internes de gravité (...)

We discuss a new mechanism that induces barotropic instability in the ocean. It is due to air-sea interaction with a quadratic drag law and horizontal viscous dissipation in the atmosphere. We (...)
