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 …

This work investigates the effect of incorporating mitigation techniques on the catastrophic
collapse of above-ground storage tanks in terms of dynamic pressures and overtopping …

Granular flows that propagate down a mountainside, then reach the sea, a lake or a river
and finally, travel underwater, is a common event on the Earth's surface. To help the …

We present results from direct numerical simulations on laminar and turbulent non-canonical
thermals with an initial rectangular density distribution at a Reynolds number of Re= 500 …

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

In the present article we consider the problem of underwater avalanches propagating over
moderate slopes. The main goal of our work is to investigate the avalanche front velocity …

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 …

We consider the time-dependent flow of a fluid of density. A box model is used for estimating
the effect of a partial (over a sector) dam break. This study is an extension of the work for a …
