Using a set of large eddy point-particle simulations, we explore the fluid dynamics of an
ejected puff resulting from a cough/sneeze. The ejection contains over 61 000 potentially …

Direct numerical simulations (DNSs) of three-dimensional cylindrical release gravity currents
in a linearly stratified ambient are presented. The simulations cover a range of stratification …

We investigate the dispersal of droplet nuclei inside a canonical room of size 10× 10× 3. 2 m
3 with a four-way cassette air-conditioning unit placed at the center of the ceiling. We use …

The present work reports some new aspects of non-axisymmetric gravity currents obtained
from laboratory experiments, fully resolved simulations and box models. Following the …

Three-dimensional highly resolved Direct Numerical Simulations (DNS) of particle-laden
gravity currents are presented for the lock-exchange problem in an original basin …

We use large eddy simulations to investigate the puff and droplet dynamics from violent
expiratory events such as coughs and sneezes in the first few seconds following an ejection …

In the present investigation, we report data from direct numerical simulations of elliptical,
finite release, Boussinesq gravity currents propagating down a uniform slope. The study …

The dynamics of non-axisymmetric turbidity currents is considered here for a range of
Reynolds numbers of O (10 4) when based on the initial height of the release. The study …

Gravity currents are buoyancy driven flows that appear in a variety of situations in nature as
well as industrial applications. Typical examples include avalanches, oil spills, and turbidity …
