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…
White light interferometry analysis for measuring thin film thickness down to few nanometers
Victor Ziapkoff, François Boulogne, Anniina Salonen +1
We present a practical white-light interferometric method, supported by an open-source Python library \textit{optifik} for automated spectrum-to-thickness deduction, enabling foam…
Enhanced Coalescence in Driven Foams
Alice Requier, Andrea Plati, Emmanuelle Rio +1
External driving leads to the emergence of unique phenomena and properties in soft matter systems. We show that driving quasi-2D foams by mechanical vibration results in significan…
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…
