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 …

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

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
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 …

Life and death of inertial particle clusters in turbulence
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 …
