Viscoelasticity reduces the droplet size in mucosalivary film fragmentation during intense respiratory events
Mogeng Li, Youssef Saade, Stéphane Zaleski +3
We examine the fundamental fluid dynamical mechanisms dictating the generation of bioaerosols in the human trachea during intense respiratory events such as coughing and sneezing,…
Implementation of integral surface tension formulations in a volume of fluid framework and their applications to Marangoni flows
Mandeep Saini, Vatsal Sanjay, Youssef Saade +2
Accurate numerical modeling of surface tension has been a challenging aspect of multiphase flow simulations. The integral formulation for modeling surface tension forces is known t…
Finite speed of sound effects on asymmetry in multibubble cavitation
Mandeep Saini, Youssef Saade, Daniel Fuster +1
Three-dimensional direct numerical simulations (DNS) are used to revisit the experiments on multibubble cavitation performed by Bremond et al. (https://doi.org/10.1063/1.2396922, P…
Vorticity-induced flow-focusing leads to bubble entrainment in an inkjet printhead: synchrotron X-ray and volume-of-fluid visualizations
Maaike Rump, Youssef Saade, Uddalok Sen +4
The oscillatory flows present in an inkjet printhead can lead to strong deformations of the air-liquid interface at the nozzle exit. Such deformations may lead to an inward directe…
Bags mediated film atomization in a cough machine
Pallav Kant, César Pairetti, Youssef Saade +3
We combine experiments and numerical computations to examine underlying fluid mechanical processes associated with bioaerosol generation during violent respiratory manoeuvres, such…
Crown formation from a cavitating bubble close to a free surface
Youssef Saade, Maziyar Jalaal, Andrea Prosperetti +1
A rapidly growing bubble close to a free surface induces jetting: a central jet protruding outwards and a crown surrounding it at later stages. While the formation mechanism of the…
Transition in a numerical model of contact line dynamics and forced dewetting
S. Afkhami, J. Buongiorno, A. Guion +4
We investigate the transition to a Landau-Levich-Derjaguin film in forced dewetting using a quadtree adaptive solution to the Navier-Stokes equations with surface tension. We use a…
