Lift at low Reynolds number [PDF]
The European Physical Journal E, 2022 Lift forces are widespread in hydrodynamics. These are typically observed for big and fast objects and are often associated with a combination of fluid inertia (i.e. large Reynolds numbers) and specific symmetry-breaking mechanisms.

Swimming at low Reynolds number [PDF]
ESAIM: Proceedings and Surveys, 2020 We address the swimming problem at low Reynolds number. This regime, which is typically used for micro-swimmers, is described by Stokes equations. We couple a PDE solver of Stokes equations, derived from the Feel++ finite elements library, to a quaternion-

Role of symmetry in driven propulsion at low Reynolds number [PDF]
Physical Review E, 2017 We theoretically and experimentally investigate low-Reynolds-number propulsion of geometrically achiral planar objects that possess a dipole moment and that are driven by a rotating magnetic field.

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.

Passive swimming in low Reynolds number flows [PDF]
Physical Review E, 2010 The possibility of microscopic swimming by extraction of energy from an external flow is discussed, focusing on the migration of a simple trimer across a linear shear flow.

Three-Dimensional Low Reynolds Number Flows near Biological Filtering and Protective Layers
Fluids, 2017 Mesoscale filtering and protective layers are replete throughout the natural world. Within the body, arrays of extracellular proteins, microvilli, and cilia can act as both protective layers and mechanosensors.

AIP Conference Proceedings, 2008 E d i t o r’s note: This is a reprint (slightly edited) of a paper of the same title that appeared in the book Physics and Our World: A Symposium in Honor of Victor F. Weisskopf, published by the American Institute of Physics (1976). The personal tone of the original talk has been preserved in the paper, which was itself a slightly edited transcript of

Three-sphere swimmer in two dimensions at low Reynolds number condition [PDF]
مهندسی مکانیک شریف, 2022 Being widely ubiquitous in fluidic mediums from aquatic environments to bodies, for the sake of their mobility, microorganisms, such as bacteria and motile cells, make use of particular swimming strategies that are counter-intuitive to that of our daily ...

Fluid-Elastic Interactions near Contact at Low Reynolds Number
Annual Review of Fluid Mechanics, 2023 Interactions between fluid flow and elastic structures are important in many naturally occurring and engineered systems. This review collects and organizes recent theoretical and experimental developments in understanding fluid-structure interactions at ...
