Excitation of the large-amplitude vibrations of a circular cylinder under normal wind conditions in the critical Reynolds number range

Journal of Fluids and Structures, 2019
The specific flow regime in which the large-amplitude vibrations of dry circular cylinders are observed in the critical Reynolds number range remains unclear because several different flow regimes overlap in this narrow range. The aerodynamic forces on a

Relationship between the critical Reynolds number and aperture for flow through single fractures: Evidence from published laboratory studies

Journal of Hydrology, 2020
An evaluation of published laboratory studies of flow through single rough fractures was conducted to establish a relationship between aperture (2b) and critical Reynolds number (Rec) under controlled conditions for physically measured fractures.

The effect of expansion ratio on the critical Reynolds number in single fracture flow with sudden expansion

Hydrological Processes, 2016
Flow in a single fracture (SF) is an important research subject in groundwater hydrology, hydraulic engineering, radioactive nuclear waste repository and geotechnical engineering. An abruptly changing aperture is a unique type of SF. This study discusses

Critical Reynolds Number for a Natural Transition to Turbulence in Pipe Flows

Physical Review Letters, 2007
Experimental results obtained over more than a century have shown that laminar flow in a circular pipe becomes naturally turbulent at a critical Reynolds number of Re approximately 2000. In this Letter a theoretical explanation, based on the minimum energy of an axisymmetric deviation (from the developed pipe flow profile), is suggested for this ...

Critical Reynolds number of the Orr-Sommerfeld equation

The Physics of Fluids, 1973
Using the straightforward Runge-Kutta procedure, the critical Reynolds number for the Orr-Sommerfeld equation has been obtained. The number is 2772.225. The corresponding wavenumber is 1.0205. These values also substantiate the accuracy of the Chebyshev polynomial expansion carried out by Orszag.

Critical transition Reynolds number for plane channel flow

Applied Mathematics and Mechanics (English Edition), 2017
The determination of the critical transition Reynolds number is of practical importance for some engineering problems. However, it is not available with the current theoretical method, and has to rely on experiments. For supersonic/hypersonic boundary layer flows, the experimental method for determination is not feasible either.

The Critical Reynolds Number for the Flow past a Sphere

Journal of the Physical Society of Japan, 1955
The stability of the flow past a sphere which has been calculated previously by use of the Galerkin method was investigated by the method of small perturbation and the Galerkin method. Thus, the ciritical Reynolds number for the flow past a sphere was determined as 51 which should be compared with the experimental value of about 100.

The critical Reynolds number for rough-wall boundary layers

Journal of Wind Engineering and Industrial Aerodynamics, 2002
Rough-wall boundary layers become aerodynamically smooth if the ‘roughness Reynolds number’ Re*=u*z0/? becomes sufficiently small. Conventional wisdom is that Re* should exceed at least two and perhaps be as much as five before viscous effects are insignificant.
