Joint Seminar: Lagrangian transport in turbulent flows

Particles or droplets of small but finite size are commonly encountered in turbulent flows, and the knowledge of their behaviour is crucial for many environmental and industrial applications. Tracers are those small particles whose density is comparable with that of the fluid: they follow the fluid streamlines. Inertial particles have a density contrast with the fluid and hence deviate from tracers trajectories. 

In this seminar, I will review some recent results, obtained from Direct Numerical Simulations, about the dynamics and statistics of tracer and inertial particles dispersed in statistically homogeneous and isotropic turbulent flows. The emphasis is on the statistical properties at small space and time scales.

In the last part of the seminar, I will report about a large-eddy simulation experiment of the convective Atmospheric Boundary Layer, seeded with tracer particles.
