Self-propulsion in viscoelastic fluids: pushers vs. pullers
Lailai Zhu, Eric Lauga, Luca Brandt
We use numerical simulations to address locomotion at zero Reynolds number in viscoelastic (Giesekus) fluids. The swimmers are assumed to be spherical, to self-propel using tangent…
Locomotion by tangential deformation in a polymeric fluid
Lailai ZHu, Minh Do-Quang, Eric Lauga +1
In several biologically relevant situations, cell locomotion occurs in polymeric fluids with Weissenberg {number} larger than one. Here we present results of three-dimensional nume…
Shear thickening in non-Brownian suspensions: an excluded volume effect
Francesco Picano, Wim-Paul Breugem, Dhrubaditya Mitra +1
Shear thickening appears as an increase of the viscosity of a dense suspension with the shear rate, sometimes sudden and violent at high volume fraction. Its origin for noncolloida…
Dispersion of swimming algae in laminar and turbulent channel flows: consequences for photobioreactors
O. A. Croze, G. Sardina, M. Ahmed +2
Shear flow significantly affects the transport of swimming algae in suspension. For example, viscous and gravitational torques bias bottom-heavy cells to swim towards regions of do…
