Stochastic low Reynolds number swimmers [PDF]
Journal of Physics: Condensed Matter, 2009 As technological advances allow us to fabricate smaller autonomous self-propelled devices, it is clear that at some point directed propulsion could not come from pre-specified deterministic periodic deformation of the swimmer's body and we need to develop strategies to extract a net directed motion from a series of random transitions in the ...

Optimal Swimming at Low Reynolds Numbers [PDF]
Physical Review Letters, 2004 Efficient swimming at low Reynolds numbers is a major concern of microbots. To compare the efficiencies of different swimmers we introduce the notion of ``swimming drag coefficient'' which allows for the ranking of swimmers. We find the optimal swimmer within a certain class of two dimensional swimmers using conformal mappings techniques.

Scattering of low-Reynolds-number swimmers [PDF]
Physical Review E, 2008 We describe the consequences of time reversal invariance of the Stokes' equations for the hydrodynamic scattering of two low Reynolds number swimmers. For swimmers that are related to each other by a time reversal transformation this leads to the striking result that the angle between the two swimmers is preserved by the scattering.

Acoustic mixing at low Reynold’s numbers [PDF]
Applied Physics Letters, 2006 In microfluidic devices, hydrodynamic flow is usually governed by very low Reynold’s numbers. Under these conditions, only laminar flow is possible. Hence, mixing in microfluidics occurs by diffusion only. Interaction of small fluid volumes and acoustic waves in a solid leads to pronounced streaming effects in the fluid inducing mixing and stirring ...

Valveless Pumping at Low Reynolds Numbers
Physical Review Applied, 2023 Pumping at low Reynolds number is a ubiquitously encountered feature, both in biological organisms and engineered devices. Generating net flow requires the presence of an asymmetry in the system, which traditionally comes from geometric flow rectifiers.

Low-Reynolds-number swimming in gels [PDF]
EPL (Europhysics Letters), 2010 Many microorganisms swim through gels, materials with nonzero zero-frequency elastic shear modulus, such as mucus. Biological gels are typically heterogeneous, containing both a structural scaffold (network) and a fluid solvent. We analyze the swimming of an infinite sheet undergoing transverse traveling wave deformations in the "two-fluid" model of a ...
