Laboratory experiments related to marine plastic pollution : a review of past work and future directions
Plastic pollution is a very active research topic for a wide variety of scientific (...)

Turbulent mixing mechanisms in heterogeneous flows : internal gravity waves and non-isoviscous turbulence
Turbulent flows play a key role in many geophysical or industrial contexts because of (...)

Bubble and Drop Breakup in Turbulence
Bubble and drop dynamics in turbulent flows are central to many environmental and industrial processes in which interfacial transport of momentum, heat, (...)

Probabilistic prediction of extreme climate events
Some of the most important events in climate dynamics are rare events related to the fluctuating nature of geophysical flows. Examples of such (...)

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. (...)

Experiments in cryogenic helium : from quantum turbulence to thermal plumes
Cryogenic liquid helium-4 is the fluid with the lowest known kinematic viscosity (1e-8 m²/s) making it a fluid of (...)

From pore-scale processes to volcanic hazards : multiscale modeling of submarine landslides, tsunamis, and lava flows
Volcanic geophysical flows involve physical processes acting over a wide (...)

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 (...)
