The motion, settling, and dispersion of microplastics in the ocean are determined by their
rotational dynamics. We present experiments on elongated, large aspect ratio, and mildly …

Turbulence can have a strong effect on the fall speed of snowflakes and ice crystals. In this
experimental study, the behaviour of thin disks falling in homogeneous turbulence is …

We experimentally investigate the settling of millimetre-sized thin disks in quiescent air. The
range of physical parameters is chosen to be relevant to plate crystals settling in the …

Plastic pollution is overflowing in rivers. A limited understanding of the physics of plastic
transport in rivers hinders monitoring, the prediction of plastic fate and restricts the …

We present the results of a set of experiments designed to measure the dispersion of non-
spherical particles in a wave–current flow. We released negatively buoyant discs, rods and …

This review delves into the dynamics of fibre-laden turbulent flows, a field that has garnered
substantial attention due to its relevance in both natural and engineering contexts. The focus …

The orientation dynamics of inertialess prolate and oblate spheroidal particles in a directly
simulated spanwise-rotating turbulent channel flow has been investigated by means of an …

Particles suspended in air are often non-spherical shapes, giving rise to shape-dependent
complex dynamical processes. Suspended non-spherical particles are associated with a …

Translational and angular velocities statistics of inertial prolate ellipsoids in a turbulent
channel flow up to Reτ = 1000 Page 1 J. Fluid Mech. (2023), vol. 966, A17, doi:10.1017/jfm.2023.420 …

Measurements of concentrations, translational velocities, orientations and rotation rates of
seven, straight and rigid fiber types in a fully developed turbulent water channel flow (one …
