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. (...)

Simple active particles in simple flows : a complex behaviour
Particles are exposed to an external flow. We will consider very simple flows, such as linear or cellular flows. In the case of (...)

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 (...)

Inertial wave turbulence vs turbulent convection in planetary cores
Planetary cores are subject to large temperature differences that can drive turbulent thermal convection. But they are also (...)

Research, growth and degrowth
After briefly recalling the biophysical limitations to the way humans occupy the planet, and defining economical growth and global degrowth, I will address three (...)

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 (...)
