Long rigid fibres in a turbulent channel flow: comparison between experiments and simulations
Defa Sun, Florian Zumbo, Christophe Pitiot +4
The dynamics of long rigid fibres transported by turbulent channel flow are investigated experimentally and numerically. Experiments use polystyrene fibres of three lengths, $\ell/…
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…
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…
Self-similar and Universal Dynamics in Drainage of Mobile Soap Films
Antoine Monier, François-Xavier Gauci, Cyrille Claudet +3
Vertical soap films drain under the influence of gravity, as indicated by the downward motion of colorful horizontal interference fringes observed on their surfaces. In this study…
