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…
Obstacle-induced lateral dispersion and nontrivial trapping of flexible fibers settling in a viscous fluid
Ursy Makanga, Mohammadreza Sepahi, Camille Duprat +1
The motion of flexible fibers through structured fluidic environments is ubiquitous in nature and industrial applications. Most often, their dynamics results from the complex inter…
Fiber buckling in confined viscous flows: an absolute instability described by the Ginzburg-Landau equation
Jean Cappello, Olivia du Roure, François Gallaire +2
We explore the dynamics of a flexible fiber transported by a viscous flow in a Hele-Shaw cell of height comparable to the fiber height. We show that long fibers aligned with the fl…
Controlling transport dynamics of confined asymmetric fibers
M. Bechert, J. Cappello, M. Daïeff +3
Transport properties of particles in confining geometries show very specific characteristics as lateral drift, oscillatory movement between lateral walls or the deformation of flex…
The deformation of a flexible fiber settling in a quiescent viscous fluid
Benjamin Marchetti, Veronica Raspa, Anke Lindner +4
The equilibrium state of a flexible fiber settling in a viscous fluid is examined using a combination of macroscopic experiments, numerical simulations and scaling arguments. We id…
Transport of flexible fibers in confined micro-channels
Jean Cappello, Mathias Bechert, Camille Duprat +3
When transported in confined geometries rigid fibers show interesting transport dynamics induced by friction with the top and bottom walls. Fiber flexibility causes an additional c…
Oscillations of confined fibers transported in microchannels
Mathias Nagel, Pierre-Thomas Brun, Helene Berthet +3
We investigate the trajectories of rigid fibers as they are transported in a pressure-driven flow, at low Reynolds number, in shallow Hele Shaw cells. The transverse confinement an…
Wetting of crossed fibers: multiple steady states and symmetry breaking
Alban Sauret, Alison D. Bick, Camille Duprat +1
We investigate the wetting properties of the simplest element of an array of random fibers: two rigid fibers crossing with an inclination angle and in contact with a droplet of a p…
Dynamics of elastocapillary rise
Camille Duprat, Jeffrey M. Aristoff, Howard A. Stone
We present the results of a combined experimental and theoretical investigation of the surface-tension-driven coalescence of flexible structures. Specifically, we consider the dyna…
