The dispersion of spherical droplets in source–sink flows and their relevance to the COVID-19 pandemic
In this paper, we investigate the dynamics of spherical droplets in the presence of a source–
sink pair flow field. The dynamics of the droplets is governed by the Maxey–Riley equation …

Accelerated decay of a Lamb–Oseen vortex tube laden with inertial particles in Eulerian–Lagrangian simulations
S Shuai, MH Kasbaoui - journal of fluid mechanics, 2022 - cambridge.org
We investigate the effect of inertial particles on the stability and decay of a prototypical vortex
tube, represented by a two-dimensional Lamb–Oseen vortex. In the absence of particles, the …

Clustering in Euler–Euler and Euler–Lagrange simulations of unbounded homogeneous particle-laden shear
Particle-laden flows of sedimenting solid particles or droplets in a carrier gas have strong
inter-phase coupling. Even at low particle volume fractions, the two-way coupling can be …
