Particle-laden turbulence: progress and perspectives
This review is motivated by the fast progress in our understanding of the physics of particle-
laden turbulence in the last decade, partly due to the tremendous advances of measurement …

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 …
