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 …

Statistical models for the dynamics of heavy particles in turbulence
When very small particles are suspended in a fluid in motion, they tend to follow the flow.
How such tracer particles are mixed, transported, and dispersed by turbulent flow has been …

Experimental study of inertial particles clustering and settling in homogeneous turbulence
We study experimentally the spatial distribution, settling and interaction of sub-Kolmogorov
inertial particles with homogeneous turbulence. Utilizing a zero-mean-flow air turbulence …

Is vortex stretching the main cause of the turbulent energy cascade?
In three-dimensional turbulence there is on average a cascade of kinetic energy from the
largest to the smallest scales of the flow. While the dominant idea is that the cascade occurs …

Improving particle drag predictions in Euler–Lagrange simulations with two-way coupling
Euler–Lagrange methods are popular approaches for simulating particle-laden flows. While
such approaches have been rigorously verified in the dilute limit (where particles do not …

The effect of Reynolds number on inertial particle dynamics in isotropic turbulence. Part 2. Simulations with gravitational effects
In Part 1 of this study (Ireland et al., J. Fluid Mech., vol. 796, 2016, pp. 617–658), we
analysed the motion of inertial particles in isotropic turbulence in the absence of gravity …

Turbophoresis of small inertial particles: theoretical considerations and application to wall-modelled large-eddy simulations
In wall-bounded turbulent flows, the wall-normal gradient in turbulence intensity causes
inertial particles to move preferentially toward the wall, leading to elevated concentration …

Multiscale preferential swee** of particles settling in turbulence
In a seminal article, Maxey (J. Fluid Mech., vol. 174, 1987, pp. 441–465) presented a
theoretical analysis showing that enhanced particle settling speeds in turbulence occur …

Correction scheme for point-particle models applied to a nonlinear drag law in simulations of particle-fluid interaction
Drag laws for particles in fluids are often expressed in terms of the undisturbed fluid velocity,
defined as the fluid velocity a particle sees before its disturbance develops in the fluid. In two …
