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 …

We present a statistical framework to account for effects of recycling and filtration in
ventilation systems for the estimation of airborne droplet nuclei concentration in indoor …

The well-mixed assumption has been widely used in predicting the spread of infectious
diseases in indoor spaces. It is to be expected that a perfect well-mixed state will not be …

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 …

In this study, the primary breakup of a high-speed diesel jet is investigated using a CFD
methodology that combines an LES model with a VOF technique for free surface capture …

Evaporative sprays are encountered in a wide range of engineering applications. Since
clustering of droplets in sprays leads to strong inhomogeneity in the spatial distribution of …

We study the dynamics of atomization of a liquid column by a coaxial gas flow with varying
gas pressures. Specifically, we analyse how the gas density increase associated with …

In a two-way coupled Euler-Lagrange (EL) simulation, a particle of size comparable to the
local grid spacing results in self-induced perturbation, which must be subtracted to obtain …

Point-particle large eddy simulations are used to characterize a vertical particle-laden round
jet in inertia-dominated regime. Both particle–fluid and particle–particle interactions are …

Annular air nozzles with different geometrical properties are used to investigate their
influence on the primary breakup of discontinuous shear-thickening suspensions. By the use …
