Vortex shedding from tapered plates

Experiments in Fluids, 2002
An experimental study of vortex shedding behind flat plates placed normal to an airstream is presented for Reynolds numbers of O(104). Apart from a parallel-sided plate used as the reference case, all the plates were tapered in the spanwise direction so that the cross-stream width of the plate varied linearly with spanwise distance along it.

Vortex shedding from spheres

Journal of Fluid Mechanics, 1974
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 in unsteady flow

Journal of Wind Engineering and Industrial Aerodynamics, 1983
Abstract Previous experiments by other workers have shown that when a cylinder vibrates in a steady flow the frequency of the vortex shedding from the cylinder can synchronize with the frequency of the cylinder's vibration. As a result the shedding frequency remains constant over a range of flow velocities, and the oscillatory forces acting on the ...

Vortex shedding in rotating flows

Geophysical & Astrophysical Fluid Dynamics, 1983
Abstract A rotating tow facility whose principle element is a long acrylic channel of rectangular cross-section has been developed. A smooth flexible belt, which can be translated along the channel axis, serves as a false horizontal floor. The system is mounted on a turntable which rotates at a constant angular speed about a vertical axis.

Vortex shedding from finned tubes

Journal of Sound and Vibration, 1975
The frequency of regular vortex shedding from a finned tube of the kind used in heat exchangers has been measured for an isolated tube in a wind tunnel. A Strouhal number expressed in terms of an effective diameter, defined as the frontal area per unit length of tube, is found to be nearly constant and to depend only on the ratio of fin spacing to tube

An electrostatic vortex shedding meter

Flow Measurement and Instrumentation, 1990
Abstract The conventional vortex shedding flowmeter performs satisfactorily in the metering of many types of fluid, but the reliability of its sensor can be questionable when exposed to hostile environments. In this paper the standard piezoelectric sensor in a commercially available flowmeter was replaced by electrodes positioned within the flow tube.

Vortex shedding in subcritical conditions

Physics of Fluids, 2003
An 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 ...

Vortex Shedding from `Taylor Columns'

Journal of the Physical Society of Japan, 1978
Visual observations are presented of the vortex wakes behind `Taylor columns' generated by a short upright cylinder moving horizontally through water in rapid rotation about a vertical axis. They demonstrate the periodic separation and rolling-up of the free shear layers around the Taylor column.

Natural and Forced Vortex Shedding

1981
Natural 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.
