Report

Autor: Kulkarni, Yash, Pairetti, Cesar, Villiers, Raphaël, Popinet, Stéphane, Zaleski, Stéphane

Direct Numerical Simulations of the injection of a pulsed round liquid jet in a stagnant gas are performed. The Reynolds and Weber numbers and the density ratio are sufficiently large for reaching a complex high-speed atomization regime. The Weber nu

Bags mediated film atomization in a cough machine

Autor: Kant, Pallav, Pairetti, César, Saade, Youssef, Popinet, Stéphane, Zaleski, Stéphane, Lohse, Detlef

We combine experiments and numerical computations to examine underlying fluid mechanical processes associated with bioaerosol generation during violent respiratory manoeuvres, such as coughing or sneezing. Analogous experiments performed in a cough m

Statistics of drops generated from ensembles of randomly corrugated ligaments

Autor: Pal, Sagar, Pairetti, Cesar, Crialesi-Esposito, Marco, Fuster, Daniel, Zaleski, Stéphane

The size of drops generated by the capillary-driven disintegration of liquid ligaments plays a fundamental role in several important natural phenomena, ranging from heat and mass transfer at the ocean-atmosphere interface to pathogen transmission. Th

Report

A numerical cough machine

Autor: Pairetti, Cesar, Villiers, Raphaël, Zaleski, Stéphane

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 Volume-Of-Fluid method with octree mesh adaptation, the latter allowing
