Effect of a weak current on wind-generated waves in the wrinkle regime
C. Nove-Josserand, S. Perrard, A. Lozano-Duran +3
We investigate numerically the influence of a weak current on wind-generated surface deformations for wind velocity below the onset of regular waves. In that regime, the liquid sur…
Motility and Phototaxis of , the Simplest Differentiated Colonial Alga
Hélène de Maleprade, Frédéric Moisy, Takuji Ishikawa +1
Green algae of the lineage, spanning from unicellular to vastly larger , are models for the study of the evolution of multicellularity, flagella…
Characterizing 1D Inertial Particle Clustering
Daniel Odens Mora, Alberto Aliseda, Alain Cartellier +1
Clustering is an important phenomenon in turbulent flows laden with inertial particles. Although this process has been studied extensively, there are still open questions about bot…
Numerical study of Bingham flow in macrosopic two dimensional heterogenous porous media
R. Kostenko, L. Talon
The flow of non-Newtonian fluids is ubiquitous in many applications in the geological and industrial context. We focus here on yield stress fluids (YSF), i.e. a material that requi…
Wind-sustained viscous solitons
M. Aulnette, M. Rabaud, F. Moisy
When wind blows at the surface of a liquid of sufficiently high viscosity, a wave packet of small amplitude is first generated, which sporadically forms large-amplitude fluid bumps…
Swimming bacteria in Poiseuille flow: the quest for active Bretherton-Jeffery trajectories
Gaspard Junot, Nuris Figueroa-Morales, Thierry Darnige +4
Using a 3D Lagrangian tracking technique, we determine experimentally the trajectories of non-tumbling E. coli mutants swimming in a Poiseuille flow. We identify a typology of traj…
