Improved settling velocity for microplastic fibers: a new shape-dependent drag model

J Zhang, CE Choi - Environmental science & technology, 2021 - ACS Publications
Microplastics are abundant in aquatic environments and are an emerging environmental
concern. The prediction of their settling velocities is central to predictions of the residence …

Experimental study of inertial particles clustering and settling in homogeneous turbulence

AJ Petersen, L Baker, F Coletti - Journal of Fluid Mechanics, 2019 - cambridge.org

Turbulence effect on disk settling dynamics

A Tinklenberg, M Guala, F Coletti - Journal of Fluid Mechanics, 2024 - cambridge.org
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 …

The effect of particle density in turbulent channel flow laden with finite size particles in semi-dilute conditions

W Fornari, A Formenti, F Picano, L Brandt - Physics of Fluids, 2016 - pubs.aip.org
We study the effect of varying the mass and volume fraction of a suspension of rigid spheres
dispersed in a turbulent channel flow. We performed several direct numerical simulations …
