A contaminant-concentration-dependent surface tension does not explain the absence of solutal Marangoni flow in evaporating droplets
Javier MartÃnez-Puig, Théophile Gaichies, Javier RodrÃguez-RodrÃguez
Theoretical models of evaporating droplets predict Marangoni flows orders of magnitude faster than those observed experimentally. While this discrepancy is often attributed to surf…
Air entrainment by an inclined smooth water jet
Théophile Gaichies, Arnaud Antkowiak, Anniina Salonen +1
Air entrainment can occur when a water jet impacts a water/air interface, a process central in various real systems, ranging from dam spills to breaking waves. Despite its prevalen…
Shape of an interface hit by an oblique jet
Theophile Gaichies, Anniina Salonen, Arnaud Antkowiak +1
We report on the shape taken by the interface of a liquid bath when hit by a smooth oblique steady jet. When the angle between the jet and the bath decreases below , a ca…
Capillary jet in a slab of foam
Théophile Gaichies, Bryan Giraud, Anniina Salonen +2
A capillary jet plunging into a quasi-2D slab of monodisperse foam of the same solution is studied experimentally. We show that the jet can have a drastic impact on the foam. At sm…
