The fragmentation of solid objects in turbulence is of paramount importance in a large
number of situations, especially for marine plastic pollution where small plastic debris are …

Heavy particles sink straight in water, while buoyant bubbles and spheres may zigzag or
spiral as they rise. The precise conditions that trigger such path-instabilities are still not …

Bubbles play an important role in the transport of chemicals and nutrients in many natural
and industrial flows. Their dispersion is crucial to understanding the mixing processes in …

Different driving algorithms for a large random jet array (RJA) were tested and their
performance characterized by comparing the statistics of the turbulence generated …

A growing number of studies is devoted to anisotropic particles in turbulent flows. In most
cases, the particles are assumed to be rigid and their deformations are neglected. We …

Turbulence modulation by inertial-range-size, neutrally buoyant particles is investigated
experimentally in a von Kármán flow. Increasing the particle volume fraction Φ v …

We report joint Lagrangian velocity and temperature measurements in turbulent thermal
convection. Measurements are performed using an improved version (extended autonomy) …

We study the three-dimensional clustering of velocity stagnation points, of nulls of the
vorticity and of the Lagrangian acceleration, and of inertial particles in turbulent flows at fixed …

We investigate the response of large inertial particle to turbulent fluctuations in an
inhomogeneous and anisotropic flow. We conduct a Lagrangian study using particles both …

We present a comparison of different particles' velocity and acceleration statistics in two
paradigmatic turbulent swirling flows: the von Kármán flow in a laboratory experiment and …
