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 (...)

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 (...)

Rare-Event triggered Transitions in aerodynamic bifurcation
The transitions between two states of a bistable system are investigated experimentally and analyzed in the framework of rare-event (...)

Breaking description in depth-averaged models
Depth-averaged models are one of the classic approaches for coastal wave description. Dispersive models of this type such as the fully nonlinear (...)
