Soft swimming: Exploiting deformable interfaces for low-Reynolds number locomotion
Renaud Trouilloud, Tony S. Yu, A. E. Hosoi +1
Reciprocal movement cannot be used for locomotion at low-Reynolds number in an infinite fluid or near a rigid surface. Here we show that this limitation is relaxed for a body perfo…
Hydrodynamic attraction of swimming microorganisms by surfaces
Allison P. Berke, Linda Turner, Howard C. Berg +1
Cells swimming in confined environments are attracted by surfaces. We measure the steady-state distribution of smooth-swimming bacteria (Escherichia coli) between two glass plates.…
No many-scallop theorem: Collective locomotion of reciprocal swimmers
Eric Lauga, Denis Bartolo
To achieve propulsion at low Reynolds number, a swimmer must deform in a way that is not invariant under time-reversal symmetry; this result is known as the scallop theorem. We sho…
Propulsion in a viscoelastic fluid
Eric Lauga
Flagella beating in complex fluids are significantly influenced by viscoelastic stresses. Relevant examples include the ciliary transport of respiratory airway mucus and the motion…
