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…
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…
