Vortex shedding from spheres has been studied in the Reynolds number range 400 < Re < 5 × 106. At low Reynolds numbers, i.e. up to Re = 3 × 103, the values of the Strouhal number as a function of Reynolds number measured by Möller (1938) have been confirmed using water flow.

Vortex shedding from two cylinders in tandem
Journal of Wind Engineering and Industrial Aerodynamics, 1988Abstract Measurements are presented of the frequencies of vortex shedding from two cylinders in tandem. In the first set of experiments both cylinders were circular. The diameter of the downstream cylinder was 22.5 mm, and three different cylinders, having diameters 23.6 mm, 24.6 mm and 25.7 mm respectively, were used in turn as the upstream cylinder.

Vortex shedding from a row of square bars
Fluid Dynamics Research, 2003Summary: Interactions of wakes in a flow past a row of square bars, which is placed across a uniform flow, are investigated by numerical simulations and experiments on the tassumption that the flow is two-dimensional and incompressible. At small Reynolds numbers the flow is steady and symmetric with respect not only to streamwise lines through the ...

A “robust” vortex-shedding anemometer
Experiments in Fluids, 1993A simple device has been constructed for the purpose of monitoring low air speeds. Two such devices have been calibrated to cover the speed range 0.4 to 1.3 m/s, and have shown linear characteristics of frequency versus speed. Flow visualization has shown the absence of end cells and the presence of parallel shedding in the case of low-aspect-ratio ...

Vortex shedding in subcritical conditions
Physics of Fluids, 2003An expressly developed apparatus has been applied to the study of the phenomenon of vortex shedding at Reynolds numbers inferior to the critical value. During previous research it was discovered that vortex shedding could be triggered under subcritical conditions by imparting low-amplitude transversal vibrations at specific frequencies to a cylinder ...

Natural and Forced Vortex Shedding
1981Natural and forced vortex shedding has been investigated experimentally over circular cylinders in the VPI water tunnel. Flow visualizations and Laser-Doppler Anemometry have been employed. Results indicate that in the lock-on region there are three distinct modes of vortex shedding.

Relationships between drag and periodic vortex shedding
AIAA Journal, 1965To the writer's knowledge, there are no published data that may be compared with Eq. (3), but the proportionality between the drag coefficient and the inverse of the Strouhal number is the trend that Hoerner presents for bluff bodies in Fig. 7 of Ref. (2).
