Drainage and convective evaporation of thin films in the presence of salt
We investigate the effect of salinity and atmospheric humidity on the drainage and lifetime of soap films in conditions (...)

Emerging sand dunes : from bed instability to patches
I will discuss in this presentation the physical processes at the origin of the emergence of sand dunes, from the coupling of wind flow, (...)

Hydraulic turbines enhanced for fish survivability : from science to engineering to the market
While hydropower is the most mature and reliable of all existing renewables, hydraulic turbines are (...)

Experimental Measurements of Energy Transfer in Rotating Turbulence
I will present work where we experimentally investigate energy currents in steady rotating turbulent flow by injecting a (...)

Local energy-flux vectors and nonlocal resonant interactions in stratified turbulence
Energy flux in the wavenumber space plays a crucial role in the cascade theory of turbulence. In anisotropic (...)

A Maxey-Riley modeling framework for Sargassum raft drift
Sargassum seaweed has historically been found in the subtropical North Atlantic gyre, providing key habitat for marine species. Since (...)

Aerodynamics of porous screens and application to aerosol collection by textile
Textiles are often used to capture airborne droplets, for example for fog harvesting. Recently, we have shown (...)

Travel between 2D ad 3D turbulent flows
We investigate two-dimensional (2D) incompressible turbulence with three velocity components. Such systems can be called 2D3C flows. Two main classes are (...)

Tropical cyclone fundamentals : The rotating-convection paradigm
Understanding how tropical cyclones form, intensify, mature and decay requires first and foremost a conceptual model. Without (...)

Experimental study of the tidal current and the wave effects on the vortex dynamics caused by a seabed obstacle for tidal turbine development
In the current context of climate change and (...)
