Motivated by the need to resolve the condensation-coalescence bottleneck in warm rain
formation, a significant number of studies have emerged in the past 15 years concerning the …

▪ 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 …

Vapour condensation in cloud cores produces small droplets that are close to one another in
size. Droplets are believed to grow to raindrop size by coalescence due to collision,. Air …

In this survey we consider the impact of turbulence on cloud formation from the cloud scale
to the droplet scale. We assess progress in understanding the effect of turbulence on the …

Spatial distributions of heavy particles suspended in an incompressible isotropic and
homogeneous turbulent flow are investigated by means of high resolution direct numerical …

Many issues in biological oceanography are regional or global in scope; however, there are
not many data sets of extensive areal coverage for marine plankton. In microbial ecology, a …

Sediment transport is studied as a function of the grain to fluid density ratio using two phase
numerical simulations based on a discrete element method for particles coupled to a …

We report experimental evidence of spatial clustering of dense particles in homogenous,
isotropic turbulence at high Reynolds numbers. The dissipation-scale clustering becomes …

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 …

The effect of turbulence on the collision rate between droplets in clouds is investigated.
Because of their inertia, water droplets can be shot out of curved streamlines of the turbulent …
