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.

Metachronal patterns in artificial cilia for low Reynolds number fluid propulsion [PDF]
Sci Adv, 2020 The influence of metachronal patterns on ciliary fluid flow has been studied using a soft robotic cilia array and simulations. Cilia are hair-like organelles, present in arrays that collectively beat to generate flow.

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.

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

Aerodynamic efficiency of a bioinspired flapping wing rotor at low Reynolds number [PDF]
Royal Society Open Science, 2018 This study investigates the aerodynamic efficiency of a bioinspired flapping wing rotor kinematics which combines an active vertical flapping motion and a passive horizontal rotation induced by aerodynamic thrust.

On the lift-optimal aspect ratio of a revolving wing at low Reynolds number [PDF]
J R Soc Interface, 2018 Lentink & Dickinson (2009 J. Exp. Biol. 212, 2705–2719. (doi:10.1242/jeb.022269)) showed that rotational acceleration stabilized the leading-edge vortex on revolving, low aspect ratio (AR) wings and hypothesized that a Rossby number of around 3, which is

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 ...

Towards the definition of a benchmark for low Reynolds number propeller aeroacoustics
Journal of Physics: Conference Series, 2021 Experimental and numerical results of a propeller of 0.3 m diameter operated in quiescent standard ambient conditions at 5000 RPM and axial velocity ranging from 0 to 20 m/s and advance ratio ranging from 0 to 0.8 are presented as a preliminary step ...
