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 …

Collisions between particles suspended in a fluid play an important role in many physical
processes. As an example, collisions of microscopic water droplets in clouds are a …

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 …

We study the behaviour of large dust grains in turbulent molecular clouds (MCs). In primarily
neutral regions, dust grains move as aerodynamic particles, not necessarily with the gas. We …

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 …

We investigate the effect of inertial particles on the stability and decay of a prototypical vortex
tube, represented by a two-dimensional Lamb–Oseen vortex. In the absence of particles, the …

Particle-laden flows of sedimenting solid particles or droplets in a carrier gas have strong
inter-phase coupling. Even at low particle volume fractions, the two-way coupling can be …

We study the formation of caustics in vortex-dominated flows. We find that only particles
starting within a critical distance of a vortex which scales as the square roots of the particle …

We study the relative velocity of inertial particles suspended in turbulent flows and discuss
implications for dust particle collisions in protoplanetary disks. We simulate a weakly …

We compute the joint distribution of relative velocities and separations of identical inertial
particles suspended in randomly mixing and turbulent flows. Our results are obtained by …
