Particle-laden turbulence: progress and perspectives

L Brandt, F Coletti - Annual Review of Fluid Mechanics, 2022 - annualreviews.org
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 …

On aeolian transport: Grain-scale interactions, dynamical mechanisms and scaling laws

O Durán, P Claudin, B Andreotti - Aeolian Research, 2011 - Elsevier
Aeolian processes involve the wind action on a sedimentary substrate, namely erosion,
sand transport and deposition. They are responsible for the emergence of aeolian dunes …

The effect of Reynolds number on inertial particle dynamics in isotropic turbulence. Part 1. Simulations without gravitational effects

PJ Ireland, AD Bragg, LR Collins - Journal of Fluid Mechanics, 2016 - cambridge.org
In this study, we analyse the statistics of both individual inertial particles and inertial particle
pairs in direct numerical simulations of homogeneous isotropic turbulence in the absence of …

Turbulent clustering of protoplanetary dust and planetesimal formation

L Pan, P Padoan, J Scalo, AG Kritsuk… - The Astrophysical …, 2011 - iopscience.iop.org
We study the clustering of inertial particles in turbulent flows and discuss its applications to
dust particles in protoplanetary disks. Using numerical simulations, we compute the radial …

Intermittency in the velocity distribution of heavy particles in turbulence

J Bec, L Biferale, M Cencini, AS Lanotte… - Journal of Fluid …, 2010 - cambridge.org
The statistics of velocity differences between pairs of heavy inertial point particles
suspended in an incompressible turbulent flow is studied and found to be extremely …

Cascade model for planetesimal formation by turbulent clustering

T Hartlep, JN Cuzzi - The Astrophysical Journal, 2020 - iopscience.iop.org
We use a newly developed cascade model of turbulent concentration of particles in
protoplanetary nebulae to calculate several properties of interest to the formation of primitive …

Transport of inertial particles in high-Reynolds-number turbulent boundary layers

T Berk, F Coletti - Journal of Fluid Mechanics, 2020 - cambridge.org
We investigate the transport of size-selected particles suspended in turbulent boundary
layers at friction Reynolds numbers up to. These are imaged simultaneously with the flow …

Risk assessment for long-and short-range airborne transmission of SARS-CoV-2, indoors and outdoors

F Poydenot, I Abdourahamane, E Caplain, S Der… - PNAS …, 2022 - academic.oup.com
Preventive measures to reduce infection are needed to combat the COVID-19 pandemic and
prepare for a possible endemic phase. Current prophylactic vaccines are highly effective to …

Dynamics of small heavy particles in homogeneous turbulence: a Lagrangian experimental study

T Berk, F Coletti - Journal of Fluid Mechanics, 2021 - cambridge.org
We investigate the behaviour of microscopic heavy particles settling in homogeneous air
turbulence. The regimes are relevant to the airborne transport of dust and droplets: the …

Life and death of inertial particle clusters in turbulence

Y Liu, L Shen, R Zamansky, F Coletti - Journal of Fluid Mechanics, 2020 - cambridge.org
Clusters of inertial particles in turbulence are usually identified from the spatial coherence of
the particle concentration field, neglecting their temporal persistence. The latter is in fact …
