Lagrangian controllability at low Reynolds number [PDF]
, 2016 In this paper, we establish a result of Lagrangian controllability for a fluid at low Reynolds number, driven by the stationary Stokes equation. This amounts to the possibility of displacing a part of a fluid from one zone to another by suitably using a ...

Research on wellhead flow detection method at low Reynolds number
International Journal of Thermofluids, 2023 The detection of wellhead fluid flow is critical in the development of low-production wells. The production status can be evaluated according to the flow of production wells. The thermal flowmeter designed in this paper mainly measures the flow of single-

Rotational Maneuvers of Copepod Nauplii at Low Reynolds Number
Fluids, 2020 Copepods are agile microcrustaceans that are capable of maneuvering freely in water. However, the physical mechanisms driving their rotational motion are not entirely clear in small larvae (nauplii).

Physics-Informed Neural Networks for Low Reynolds Number Flows over Cylinder
Energies, 2023 Physics-informed neural network (PINN) architectures are recent developments that can act as surrogate models for fluid dynamics in order to reduce computational costs.

Noisy swimming at low Reynolds numbers [PDF]
Physical Review E, 2009 Small organisms (e.g., bacteria) and artificial microswimmers move due to a combination of active swimming and passive Brownian motion. Considering a simplified linear three-sphere swimmer, we study how the swimmer size regulates the interplay between self-driven and diffusive behavior at low Reynolds number.

Biotechnology at low Reynolds numbers
Biophysical Journal, 1996 The shrinking of liquid handling systems to the micron and submicron size range entails moving into the area of small Reynolds numbers. The fluid dynamics in this regime are very different from the macroscale. We present an intuitive explanation of how the different physics of small Reynolds numbers flow, along with microscopic sizes, can influence ...

Optimal Strokes of Low Reynolds Number Linked-Sphere Swimmers
Applied Sciences, 2019 Optimal gait design is important for micro-organisms and micro-robots that propel themselves in a fluid environment in the absence of external force or torque.

Low-Reynolds-number swimming in a capillary tube [PDF]
Journal of Fluid Mechanics, 2013 AbstractWe use the boundary element method to study the low-Reynolds-number locomotion of a spherical model microorganism in a circular tube. The swimmer propels itself by tangential or normal surface motion in a tube whose radius is of the order of the swimmer size.

Numerical simulation of low reynolds number 2-d rough blade compressor cascade
Frontiers in Energy Research, 2022 In this paper, a double-circular-arc cascade was used as the research object to study the effect of roughness on the compressor cascade under the conditions of different incoming attack angles. The Reynolds number of the cascade is 1.5×105 .

Three-Sphere Low Reynolds Number Swimmer with a Cargo Container [PDF]
, 2008 A recently introduced model for an autonomous swimmer at low Reynolds number that is comprised of three spheres connected by two arms is considered when one of the spheres has a large radius.
