Reynolds number visual. A vortex street around a cylinder--for any fluid, cylinder size and fluid speed, provided that there is a Reynolds number of between ~40 and 103.

The animation below (courtesy of Cesareo de la Rosa Siqueira at the University of Sao Paulo, Brazil) shows how a von Karman vortex street develops behind a cylinder moving through a fluid

Laminar and Turbulent Fluid Flows & Reynolds Number

The characteristics of the flow whether it is laminar or turbulent is determined by a dimensionless parameter known as Reynold's number.

Self-organization - Scholarpedia. Figure 5: Example of an instability hierarchy in fluids and gases. a) Liquid flow around a cylinder at small speed (Reynolds number r=10−2 ). b) At an increased, critical Reynolds number, a pair of vortices is formed. c) At still higher Reynolds number, the vortices start an oscillatory movement. d) What may be called “weak turbulence” is emerging. e) Fully developed turbulence (after Feynman et al. (1965)).

In fluid mechanics, the Reynolds number (Re) is a dimensionless number that gives a measure of the ratio of inertial forces to viscous forces for given flow conditions. The Reynolds number is an.

High Reynolds Number flow over Circular Cylinder

A simple cylinder in a steady flow creates a beautiful wake pattern known as a von Karman vortex street. The image above shows several examples of this pattern. Flow is from bottom to top, and the Reynolds number is increasing from left to right. In the experiment, this increasing Reynolds number corresponds to increasing the flow velocity because the cylinder size, fluid, and temperature were all fixed.

[image] Fluid flows can be divided into two different types: laminar flows and turbulent flows. Laminar flow occurs when the fluid flows in infinitesimal parallel layers with no disruption between them. In laminar flows…
