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 (...)

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 (...)

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 (...)

Transport of oxygen in the wake of a high-Re bubble rising in a thin-gap cell
I will present new experimental results concerning mass transfer at the interface of an isolated bubble rising in a (...)

Exploring Surface Wettability Effects on Boiling and Nucleation Phenomena
Starting in 2005, our research has delved into the critical influence of surface wettability on boiling and nucleation (...)

Particles floating on turbulent water
Every year, millions of tons of plastics enter the ocean. Devising effective strategies to mitigate such pollution requires the quantitative understanding (...)
