Evaporation of water
Odile Carrier,Noushine Shahidzadeh-Bonn,Rojman Zargar,Mounir Aytouna,Mehdi Habibi,Jens Eggers,Daniel Bonn +6 more
TL;DR: In this paper, the evaporation rate from single drops as well as collections of drops on a solid substrate, both experimentally and theoretically, is studied. But the authors focus on the single drop and do not consider the effect of diffusion of water through the air.
Journal ArticleDOI
Impact dynamics of surfactant laden drops: dynamic surface tension effects
TL;DR: In this article, the impact and subsequent retraction of aqueous surfactant-laden drops upon high-speed impact on hydrophobic surfaces were studied, and the authors provided quantitative measurements showing that both the expansion and the retraction dynamics depend not only on the equilibrium surface tension (ST) but also on the dynamic tension of the surfactants solutions.
Journal ArticleDOI
Effect of surface tension variations on the pinch-off behavior of small fluid drops in the presence of surfactants.
TL;DR: It is shown experimentally that surfactants can change the thinning rate of fluid necks undergoing rupture and the surface tension in the neck region changes with time, as a result of surfactant depletion.
Journal ArticleDOI
Drop formation in non-Newtonian fluids.
Mounir Aytouna,José Paredes,Noushine Shahidzadeh-Bonn,Sébastien Moulinet,Christian Wagner,Yacine Amarouchene,Jens Eggers,Daniel Bonn +7 more
TL;DR: It is found that the pinch-off of droplets of yield stress and shear thinning fluids remains very similar to that of constant viscosity Newtonian liquids, and consequently thinning in shear flow does not imply athinning in elongational flow.
Journal ArticleDOI
Dynamic interfacial tension effects in the rupture of liquid necks
M. Robert de Saint Vincent,Julien Petit,Mounir Aytouna,Jean-Pierre Delville,Daniel Bonn,Hamid Kellay +5 more
TL;DR: In this paper, the authors examine the rupture of fluid necks during droplet formation of surfactant-laden liquids and observe deviations from expected behaviour for the pinch-off of such necks.
