Self-learning how to swim at low Reynolds number [PDF]
, 2018 Synthetic microswimmers show great promise in biomedical applications such as drug delivery and microsurgery. Their locomotion, however, is subject to stringent constraints due to the dominance of viscous over inertial forces at low Reynolds number (Re ...

Low Reynolds Number Swimming Near Interfaces in Multi-Fluid Media
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.

What is the Reynolds Number of the Reynolds' Layer? [PDF]
, 1999 Several authors have now suggested that some interstellar clouds above the plane of the Galaxy are interacting with the Reynolds' layer, the warm ionized gas extending well above (H~910 pc) the Galactic plane (Reynolds 1993). Characterizing the interaction between these clouds and their surroundings should be useful in understanding one source of ...

High-Reynolds-Number Flow past a Pipe
Journal of Fluid Science and Technology, 2013 The present aim is to reveal the flow past a pipe which is immersed parallel to the mainstream at high Reynolds numbers. In a wind tunnel, we carry out (1) base-pressure measurements, (2) velocity-fluctuation measurements using a hot-wire anemometer and (

Reynolds number calculation and applications for curved wall jets [PDF]
INCAS Bulletin, 2014 The current paper refers to the preliminary estimation of the Reynolds number for curved wall jets. This, in turn, can be a useful tool for controlling the boundary layer mesh size near a generic curved wall which is wetted by a thin, attached jet.

Low Reynolds Number Rotor Blade Aerodynamic Analysis
MATEC Web of Conferences, 2019 Maintaining a steady hover flight in a rotorcraft usually requires high energy input. The aim of the paper is to prove that it is possible to vastly reduce energy use in a rotorcraft by reducing the disc loading.
