Effects of Damping and Reynolds Number on Vortex-Induced Vibrations [PDF]

open access: yes, 2007
Vortex-induced vibrations have been studied experimentally with emphasis on damping and Reynolds number effects. Our system was an elastically-mounted rigid circular cylinder, free to oscillate only transverse to the flow direction, with very low ...

Vortex-induced vibration of cylinder under sub-critical Reynolds number

open access: yesZhongguo Jianchuan Yanjiu, 2022
ObjectiveIn order to achieve the accurate prediction of the amplitude response of a vortex-induced vibrating cylinder under the sub-critical Reynolds number, a method for establishing a Cl-A/D (lift coefficient-amplitude ratio)model of the forced ...

Model-based scaling of the streamwise energy density in high-Reynolds-number turbulent channels [PDF]

open access: yes, 2013
We study the Reynolds number scaling of a gain-based, low-rank approximation to turbulent channel flows, determined by the resolvent formulation of McKeon & Sharma (2010), in order to obtain a description of the streamwise turbulence intensity from ...

Three-dimensional structure of a low-Reynolds-number turbulent boundary layer [PDF]

open access: yes, 2004
A low-Reynolds-number zero-pressure-gradient incompressible turbulent boundary layer was investigated using a volumetric imaging technique. The Reynolds number based on momentum thickness was 700.

Mass or heat transfer inside a spherical gas bubble at low to moderate Reynolds number [PDF]

open access: yes, 2013
Mass (or heat) transfer inside a spherical gas bubble rising through a stationary liquid is investigated by direct numerical simulation. Simulations were carried out for bubble Reynolds number ranging from 0.1 to 100 and for Péclet numbers ranging from 1

Turbulence Model Selection for Low Reynolds Number Flows. [PDF]

open access: yesPLoS 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.

Nonlinear aspects of high Reynolds number channel flows [PDF]

open access: yes, 2010
This paper considers the flow in a two-dimensional channel at high Reynolds number, with wall deformations which can lead to flow separation. An asymptotic model is proposed by using the successive complementary expansion method with generalized ...

What is the Reynolds Number of the Reynolds' Layer? [PDF]

open access: yes, 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 ...
