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-

Low Reynolds Number Swimming Near Interfaces in Multi-Fluid Media [PDF]
Applied Sciences, 2021 Microorganisms often swim within heterogeneous fluid media composed of multiple materials with very different properties. The swimming speed is greatly affected by the composition and rheology of the fluidic environment.

Clustering of fast gyrotactic particles in low-Reynolds-number flow. [PDF]
PLoS ONE, 2022 Systems of particles in turbulent flows exhibit clustering where particles form patches in certain regions of space. Previous studies have shown that motile particles accumulate inside the vortices and in downwelling regions, while light and heavy non ...

Aerodynamics of two parallel bristled wings in low Reynolds number flow [PDF]
Scientific Reports, 2022 Most of the smallest flying insects use bristled wings. It was observed that during the second half of their upstroke, the left and right wings become parallel and close to each other at the back, and move upward at zero angle of attack.

Turbulence Model Selection for Low Reynolds Number Flows. [PDF]
PLoS ONE, 2016 One of the major flow phenomena associated with low Reynolds number flow is the formation of separation bubbles on an airfoil's surface. NACA4415 airfoil is commonly used in wind turbines and UAV applications.

The performance of discrete models of low reynolds number swimmers
Mathematical Biosciences and Engineering, 2015 Swimming by shape changes at low Reynolds number is widely used in biology andunderstanding how the performance of movement depends on the geometric pattern ofshape changes is important to understand swimming of microorganisms and in designing ...

Propulsion Mechanism of Flexible Microbead Swimmers in the Low Reynolds Number Regime [PDF]
Micromachines, 2020 A propulsion mechanism for a flexible microswimmer constructed from superparamagnetic microbeads with different diameters and subjected to an oscillating field was studied experimentally and theoretically herein. Various types of artificial swimmers with

Characteristics of Low Reynolds Number Shear-Free Turbulence at an Impermeable Base [PDF]
The Scientific World Journal, 2014 Shear-free turbulence generated from an oscillating grid in a water tank impinging on an impermeable surface at varying Reynolds number 74≤Rel≤570 was studied experimentally, where the Reynolds number is defined based on the root-mean-square (r.m.s ...

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.

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.
