Optimised hyperbolic microchannels for the mechanical characterisation of bio-particles
Yanan Liu, Konstantinos Zografos, Joana Fidalgo +8
The transport of bio-particles in viscous flows exhibits a rich variety of dynamical behaviour, such as morphological transitions, complex orientation dynamics or deformations. Cha…

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…

Creep and fluidity of a real granular packing near jamming
Van Bau Nguyen, Thierry Darnige, Ary Bruand +1
We study the internal dynamical processes taking place in a granular packing below yield stress. At all packing fractions and down to vanishingly low applied shear, a logarithmic c…
