Spatial evolution of multi-scale droplet clusters in an evaporating spray

N Pandurangan, S Sahu - Physics of Fluids, 2022 - pubs.aip.org
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 …

Heterogeneous Dynamics of Sheared Particle-Laden Fluid Interfaces with Janus Particle Doping

Y Qiao, Z Liu, X Ma, NC Keim, X Cheng - Langmuir, 2023 - ACS Publications
The formation of particle clusters can substantially modify the dynamics and mechanical
properties of suspensions in both two and three dimensions. While it has been well …

Characterization of droplet clusters in a turbulent multiphase gas cloud using a model cough simulator

AK Vishwakarma, S Sahu - Physics of Fluids, 2024 - pubs.aip.org
This study aims to investigate the transport of droplets ejected from an artificial cough
simulator, which releases a turbulent puff of droplets into the surrounding air, closely …

Evolution of clusters of turbulent reattachment due to shear layer instability in flow past a circular cylinder

G Chopra, S Mittal, RI Sujith - Physics of Fluids, 2024 - pubs.aip.org
We perform large eddy simulations of flow past a circular cylinder for the Reynolds number
