Lift at low Reynolds number [PDF]
The European Physical Journal E, 2023 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. In contrast, the properties of viscosity-dominated (i.e.

High–Reynolds Number Taylor-Couette Turbulence [PDF]
Annual Review of Fluid Mechanics, 2016 Taylor-Couette flow, the flow between two coaxial co- or counter-rotating cylinders, is one of the paradigmatic systems in the physics of fluids. The (dimensionless) control parameters are the Reynolds numbers of the inner and outer cylinders, the ratio of the cylinder radii, and the aspect ratio.

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 ...

Spectral analysis of the budget equation in turbulent channel flows at high Reynolds number [PDF]
Journal of Fluid Mechanics, 2018 The transport equations for the variances of the velocity components are investigated using data from direct numerical simulations of incompressible channel flows at friction Reynolds number ( $Re_{\unicode[STIX]{x1D70F}}$ ) up to $Re_{\unicode[STIX ...

Stochastic low Reynolds number swimmers [PDF]
Journal of Physics: Condensed Matter, 2009 As technological advances allow us to fabricate smaller autonomous self-propelled devices, it is clear that at some point directed propulsion could not come from pre-specified deterministic periodic deformation of the swimmer's body and we need to develop strategies to extract a net directed motion from a series of random transitions in the ...

Holography of the QGP Reynolds number
Nuclear Physics B, 2017 The viscosity of the Quark–Gluon Plasma (QGP) is usually described holographically by the entropy-normalized dynamic viscosity η/s. However, other measures of viscosity, such as the kinematic viscosity ν and the Reynolds number Re, are often useful, and ...

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 (
