Lacunarity in a Two-Dimensional Atomizing Liquid Jet
Guangnian Ji, Yash Kulkarni, Stéphane Zaleski
Atomization stretches and folds the liquid--gas interface before fragmenting it into ligaments and droplets, making fractal measures a natural descriptor of the lacunarity of the f…
Holes in Sheets: Double-Threshold Rupture of Draining Liquid Films
Ayush K. Dixit, Chunheng Zhao, Stéphane Zaleski +2
Classical rupture is attributed to molecular (van der Waals) forces acting at nanometric thicknesses. Nonetheless, micron-thick liquid sheets routinely perforate far above the scal…
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,…
The atomizing pulsed jet
Yash Kulkarni, Cesar Pairetti, Raphaël Villiers +2
Direct Numerical Simulations of the injection of a pulsed round liquid jet in a stagnant gas are performed in a series of runs of geometrically progressing resolution. The Reynolds…
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…
A numerical cough machine
Cesar Pairetti, Raphaël Villiers, Stéphane Zaleski
We introduce a simplified model of physiological coughing or sneezing, in the form of a thin liquid layer subject to a rapid (30 m/s) air stream. The setup is simulated using the V…
Host-to-Host Airborne Transmission As a Multiphase Flow Problem For Science-Based Social Distance Guidelines
S. Balachandar, S. Zaleski, A. Soldati +2
COVID-19 pandemic has strikingly demonstrated how important it is to develop fundamental knowledge related to generation, transport and inhalation of pathogen-laden droplets and th…
Planar Jet Stripping of Liquid Coatings: Numerical Studies
Wojciech Aniszewski, Stéphane Zaleski, Stéphane Popinet +1
In this paper, we present a detailed example of numerical study of flm formation in the context of metal coating. Subsequently we simulate wiping of the film by a planar jet. The s…
