The role of fluid inertia on the orientation of settling anisotropic particles - Application to cloud microphysics
Understanding the angular dynamics of non-spherical particles in turbulent (...)

Scale-by-scale turbulence energy in non-homogeneous turbulence
A theory of non-homogeneous turbulence is developed and applied to boundary-free shear flows. The theory introduces assumptions of (...)

Turbulent disperse two-phase flows : simulations and data-driven modeling
Many natural and industrial processes involve the flow of solid particles or liquid droplets whose dynamical evolution (...)

Ultimate Rayleigh-Bénard and Taylor-Couette turbulence
Rayleigh-Bénard flow - the flow in a box heated from below and cooled from above - and Taylor-Couette flow - the flow between two coaxial (...)

Lagrangian investigation of particle dispersion in turbulence : inhomogeneous seeding and pair dispersion
The question of particle dispersion in turbulent flows is fundamental to understanding (...)

Geoinspired bioreactors : from Earth’s precession to stem cell production
Inspired by the precession of the Earth, a new bladeless mixer has been designed, which consists of a tilted and (...)

Flow patterns and machine learning and to develop predictive reduced order models
Modeling turbulent flows and solving the engineering problem mentioned, is a highly complex task that requires (...)

Le projet 22INTERNAL s’inscrit dans le cadre des études de la turbulence stratifiée menées au LEGI depuis plusieurs années. En effet, la surface de la mer agitée est un exemple typique de turbulence (...)

Turbulent rotating Rayleigh-Benard convection : the geostropic regime
Most geo- and astrophysical flows are driven by strong thermal forcing and affected by high rotation rates. In these (...)
