Exploring boundary layer flows in complex terrain using Doppler wind lidar and multi-rotor aircraft
In this presentation, I will discuss two technological innovations developed at the (...)

A multifractal approach to handle rainfall and wind’s extreme variability, and examples of associated applications
Rainfall and wind are known to exhibit extreme variability over a wide range of (...)

Flows and forces induced by the translation of a particle in a linearly stratified or rotating flow
Situations involving particles, drops or bubbles moving within a fluid subjected to (...)

Dynamical stall and stall dynamics
We present experimental results on the flow around wing profiles around the stall angles. On a curved airfoil in an anechoic wind tunnel, we study the noise (...)

The Wrath of the Small : Fragmentation of Bubbles in Turbulence by Small Eddies
From milk homogenization to whitecaps in the ocean, fragmentation of bubbles and droplets in turbulence (...)

Turbulence in and out of equilibrium
Kolmogorov postulated in 1941 that the small scales of turbulent flows away from boundaries can be considered universal if the Reynolds number is (...)

Zonal jets and vortex clusters in laboratory experiments
We use an experimental approach to address the questions of zonal jets and vortex clusters formation typical of planetary flows. A (...)

Instabilities and Lagrangian Transport
In uniform stratification, a horizontally propagating, vertically bounded internal tide eventually gives up energy to subharmonics through triad resonant (...)

Multi-scale interactions in the atmosphere. Application to the prediction of heat waves and urban heat islands
The climate system is described by approaches focusing on Zonal jets, Waves and (...)

Des interactions fluide-structure dans le domaine du naval à la R&D dans le domaine des énergies marines renouvelables
Avec l’accroissement de la taille des navires marchands de type (...)
