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 (...)

Interfacial tension effects, fragmentation and Marangoni flows
Interfacial tension plays a crucial role in multiphase configurations as for fragmentation and Marangoni flows. Liquid jet (...)

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. (...)

Les 12 et 13 mars 2026 sur le site du Laboratoire des Écoulements Géophysiques et Industriels (LEGI) à Grenoble, le groupe « Machines/ Cavitation » de la Société Hydrotechnique de France (SHF) avec la (...)
