Superflows around corners
Thomas Frisch, Christophe Josserand, Sergio Rica
We investigate analytically and numerically the dynamics of a two-dimensional superflow governed by the Gross-Pitaevskii equation passing over finite-size rectangular obstacles: an…
Birth of a bubble: Drop impact onto a thin liquid film for an immiscible three-fluid system
Pierre-Antoine Maës, Alidad Amirfazli, Christophe Josserand
When a drop impacts a solid substrate or a thin liquid film, a thin gas disc is entrapped due to surface tension, the gas disc retracts into one or several bubbles. While the evolu…
Geometry-driven jets underlie dispersal of plants and fungi by raindrops
Ana-Maria Bratu, Valentin Laplaud, Antoine Garcia +4
The impact of droplets on concave surfaces is poorly understood, although it is relevant to a mode of dispersal that has evolved independently in several species of plants and fung…
Three-dimensional flow around and through a porous screen
Olivier C. Marchand, Sophie Ramananarivo, Camille Duprat +1
We investigate the three-dimensional flow around and through a porous screen for various porosities at high Reynolds number Re = O(10000). Historically, the study of this problem w…
Making superhydrophobic splashes by surface cooling
R. Grivet, A. Huerre, T. Séon +1
We study experimentally the enhancement of splashing due to solidification. Investigating the impact of water drops on dry smooth surfaces, we show that the transition velocity to…
Rheotaxis of chiral bacteria: from single-cell behavior to a population-level description
Gustave Ronteix, Christophe Josserand, Adélaïde Lety-Stefanka +2
Due to their morphology, the dynamics of bacteria suspended in media can exhibit complex behaviors. In the presence of a shear, swimming bacteria experience a drift perpendicular t…
