A vertically-Lagrangian, non-hydrostatic, multilayer model for multiscale free-surface flows
I will present a semi-discrete, multilayer set of equations describing the three-dimensional motion (...)

Modélisation des fluides géophysiques : comment aller au delà du miel ?
Les écoulements astrophysiques et géophysiques sont souvent caractérisés par une gamme pharaonique d’échelles spatio-temporelles. (...)

Transport of long flexible fibres in a turbulent wall-bounded flow
The dynamics of flexible fibres in wall-bounded turbulent flows is a topic of great concern in various fields, such as (...)

Active skin friction reduction from low to high Reynolds numbers
This talk presents recent advances in the control of turbulent boundary layer (TBL) at the Centre for Turbulence Control, (...)

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 (...)
