▪ Abstract Turbulence is ubiquitous in atmospheric clouds, which have enormous turbulence
Reynolds numbers owing to the large range of spatial scales present. Indeed, the ratio of …

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 …

We report on the Lagrangian statistics of acceleration of small (sub-Kolmogorov) bubbles
and tracer particles with Stokes number St≪ 1 in turbulent flow. At a decreasing Reynolds …

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 …

A new algorithm based on post-processing of saved trajectories has been developed and
applied to obtain well-sampled backward and forward relative dispersion statistics in …

Turbulence can disperse a concentrated parcel of pollutants at a rate over nine orders of
magnitude higher than its purely diffusive counterpart. One intriguing signature of turbulent …

Mixing and collisions of inertial particles at the small scales of turbulence can be
investigated by considering how pairs of particles move relative to each other. In real …

Ice particles play an important role in precipitation and radiation transfer in stratiform mixed‐
phase clouds. Lagrangian ice particle tracking in mixed‐phase clouds is applied in both a 3 …

Due to the significant reduction in water droplet size caused by the strong air-water
interaction in the spray nozzle, air-mist spray is one of the promising technologies for …

Using direct numerical simulation (DNS), we investigate how gravity modifies the multiscale
dispersion of bidisperse inertial particles in isotropic turbulence. The DNS has a Taylor …
