Quantifying the liquid flow between a soap film and a vertical meniscus
Alexandre Vigna-Brummer, Simon Cox, Médéric Argentina +2
Fluid exchange between a soap film and its bounding menisci governs film drainage and stability, with direct implications for the lifetime of surface bubbles and liquid foams. Desp…
Exponential Stress Relaxation Driven by Elementary Plastic Events in Non-Ageing Liquid Foams
F. Schott, B. Dollet, C. M. Schlepütz +5
Liquid foams are archetypal athermal amorphous solids whose elasticity arises from the jamming of densely packed bubbles. We investigate the stress relaxation of non-ageing liquid…
Soap Film Drainage Using a Centrifugal Thin Film Balance
Antoine Monier, Kévin Gutierrez, Cyrille Claudet +3
Surface bubbles are an abundant source of aerosols, with important implications for climate processes. In this context, we investigate the stability and thinning dynamics of soap f…
Flowing menisci: coupled dynamics and liquid exchange with soap films
Alexandre Vigna-Brummer, Antoine Monier, Isabelle Cantat +2
Liquid foams exhibit menisci whose lengths range from hundreds of microns in microfoams to several centimeters in macroscopic bubble arrangements. These menisci thin under gravity…
Undulatory underwater swimming: Linking vortex dynamics, thrust, and wake structure with a biorobotic fish
Christophe Brouzet, Christophe Raufaste, Médéric Argentina
Flapping-based propulsive systems rely on fluid-structure interactions to produce thrust. At intermediate and high Reynolds numbers, vortex formation and organization in the wake o…
Multiscale stress dynamics in sheared liquid foams revealed by tomo-rheoscopy
Florian Schott, Benjamin Dollet, Stéphane Santucci +5
Rheology aims at quantifying the response of materials to mechanical forcing. However, standard rheometers provide only global macroscopic quantities, such as viscoelastic moduli.…
