The macroscopic contact angle of water on ice
W. Sarlin, D. V. Papa, R. Grivet +4
Wettability quantifies the affinity of a liquid over a substrate, and determines whether the surface is repellent or not. When both the liquid and the solid phases are made of the…
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…
A microfluidic band-pass filter for flexible fiber separation
Li Zhibo, Bielinski Clément, Lindner Anke +2
The control of particle trajectories in structured microfluidic environments has significantly advanced sorting technologies, most notably through deterministic lateral displacemen…
Transport of spherical microparticles in a 3D vortex flow
Marine Aulnette, Noa Burshtein, Arash Alizad Banaei +5
Particles are common in biological and environmental flows and are widely used in industrial and pharmaceutical applications. Their motion and flow dynamics are strongly affected b…
A mixing length model for arbitrary geometry: the case of parallel flows
Vincent Labarre, Christophe Josserand, Martine Le Berre +3
We present a phenomenological model for the mixing length used in turbulence models. It has the advantage of naturally accounting for the object's geometry while satisfying the sta…
