Swirling Instability of the Microtubule Cytoskeleton
David B. Stein, Gabriele De Canio, Eric Lauga +2
In the cellular phenomena of cytoplasmic streaming, molecular motors carrying cargo along a network of microtubules entrain the surrounding fluid. The piconewton forces produced by…
Efficiency optimization and symmetry-breaking in a model of ciliary locomotion
Sebastien Michelin, Eric Lauga
A variety of swimming microorganisms, called ciliates, exploit the bending of a large number of small and densely-packed organelles, termed cilia, in order to propel themselves in…
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…
A two-dimensional model of low-Reynolds number swimming beneath a free surface
Darren Crowdy, Sungyon Lee, Ophir Samson +2
Biological organisms swimming at low Reynolds number are often influenced by the presence of rigid boundaries and soft interfaces. In this paper we present an analysis of locomotio…
Autophoretic locomotion from geometric asymmetry
Sebastien Michelin, Eric Lauga
Among the few methods which have been proposed to create small-scale swimmers, those relying on self-phoretic mechanisms present an interesting design challenge in that chemical gr…
Taylor's swimming sheet: Analysis and improvement of the perturbation series
Martin Sauzade, Gwynn J. Elfring, Eric Lauga
In G.I. Taylor's historic paper on swimming microorganisms, a two dimensional sheet was proposed as a model for flagellated cells passing traveling waves as a means of locomotion.…
