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 (...)

Antoine Mathieu, ancien doctorant LEGI et maintenant post-doctorant aux USA avec Tom Hsu (Civil and Environmental Engineering, Université du Delaware) a remporté ce prix de plus belle image lors de (...)

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 (...)

Nascent fractal scaling during flat plate boundary layer transition to turbulence
As a boundary layer developing on a smooth surface transitions from a laminar to a turbulent state, spatially (...)
