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 …

Numerical simulations are extensively used to investigate the motion of suspended particles
in a fluid and their influence on the dynamics of the overall flow. Contexts range from the …

Climate projections continue to be marred by large uncertainties, which originate in
processes that need to be parameterized, such as clouds, convection, and ecosystems. But …

Abstract Representation of cloud microphysics is a key aspect of simulating clouds. From the
early days of cloud modeling, numerical models have relied on an Eulerian approach for all …

Cloud entrainment, the mixing between cloudy and clear air at the boundary of clouds,
constitutes one paradigm for the relevance of small scales in the Earth system: By regulating …

Numerical simulation of turbulent fluid dynamics needs to either parametrize turbulence—
which introduces large uncertainties—or explicitly resolve the smallest scales—which is …

In the last ten years, advances in experimental techniques have enabled remarkable
discoveries of how the dynamics of thin gas films can profoundly influence the behavior of …

In this study, we analyse the statistics of both individual inertial particles and inertial particle
pairs in direct numerical simulations of homogeneous isotropic turbulence in the absence of …

The influence of aerosol concentration on the cloud-droplet size distribution is investigated
in a laboratory chamber that enables turbulent cloud formation through moist convection …

At sufficient mass loading and in the presence of a mean body force (eg gravity), an initially
random distribution of particles may organize into dense clusters as a result of momentum …
