The dynamics of heavy particles suspended in turbulent flows is of fundamental importance
for a wide range of questions in astrophysics, atmospheric physics, oceanography, and …

In this paper, we contrast two theoretical models for the spatial clustering of inertial particles
in isotropic turbulence, one by Chun et al (2005 J. Fluid Mech. 536 219) and the other by …

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 …

In this paper, we consider the physical mechanism for the clustering of inertial particles in
the inertial range of isotropic turbulence. We analyze the exact, but unclosed, equation …

We analyze the tumbling of small nonspherical, axisymmetric particles in random and
turbulent flows. We compute the orientational dynamics in terms of a perturbation expansion …

We study the orientation statistics of spheroidal, axisymmetric microswimmers, with shapes
ranging from disks to rods, swimming in chaotic, moderately turbulent flows. Numerical …

We investigate experimentally the spatial distributions of heavy and neutrally buoyant
particles of finite size in a fully turbulent flow. Because their Stokes number (ie, the ratio of …

Spatial clustering of identical particles falling through a turbulent flow enhances the collision
rate between the falling particles, an important problem in aerosol science. We analyze this …

Recent studies show that spherical motile microorganisms in turbulence subject to
gravitational torques gather in down-welling regions of the turbulent flow. By analyzing a …

'Preferential concentration'(Squires & Eaton, Phys. Fluids, vol. A3, 1991, pp. 1169–1178)
refers to the clustering of inertial particles in the high strain, low-rotation regions of …
