Studying turbulent flows with DNS : from faster pseudo-spectral algorithms to anisotropic Kolmogorov laws
This talk presents two complementary advances in the numerical study of turbulent flows. (...)

Probing curved spacetime geometry in a giant quantum vortex flow
Gravity simulators are laboratory systems where small excitations like sound or surface waves behave as fields propagating on a (...)

Interfaces and turbulence : fragmentation, Marangoni and internal gravity waves
Interfacial tension plays a crucial role in multiphase configurations as for fragmentation and Marangoni flows. (...)

Simulating bubbles and their role in shockwave and ultrasound therapies
High-intensity acoustic waves are increasingly used to manipulate matter in biological settings, with applications ranging (...)

Three-dimensional metrology based on plenoptic imaging : application to the characterization of liquid-gas interfaces.
Two-phase flows are present in many applications, both industrial and (...)

Overturning events in stratified turbulence
I will present the latest results of the investigation of stratified turbulence in the Coriolis facility. Energy is injected into linearly stratified (...)

Air entrainment by plunging jets and droplet trains
Transportation of air into the liquid phase in the form of bubbles is a well-known phenomenon. This ubiquitous and complex process facilitates (...)

Mélange de jets hétérogènes : Effets de densité et de viscosité
Dans cette étude, nous nous intéressons aux statistiques conditionnées à l’interface de jets à viscosité, densité et diffusivité variable. (...)

Absolute equilibrium dynamics in 3d turbulence
Turbulence is ubiquitous in atmospheric winds, ocean currents, and industrial flows and presents complex out-of-equilibrium dynamics, characterized (...)

Geostrophic turbulent convection
Buoyantly-driven rotating turbulence occurs in planetary and stellar interiors, where it is responsible for mixing and transport (of heat, composition, momentum, (...)
