Vortex streets - Open Access .click

Physics of Fluids, 2009
We consider streamline patterns associated with single and double von Kármán point vortex streets on the surface of a nonrotating sphere, with and without pole vortices. The full family of streamline patterns are identified and the topological bifurcations from one pattern to another are depicted as a function of latitude and pole strength. The process

Experimental Investigation of Vortex Streets

Journal of the Physical Society of Japan, 1965
Vortex streets behind circular cylinders and fiat plates were investigated experimentally in a water tank. Photography and hot-wire techniques were used. The important points resulting from the investigation are as follows. (1) Walls increase the stability of the wake. (2) Two parallel walls have a compressing effect on the vortex street.

The dynamics of vortex streets in channels

Physics of Fluids, 2015
We develop a model to numerically study the dynamics of vortex streets in channel flows. Previous work has studied the vortex wakes of specific vortex generators. Here, we study a wide range of vortex wakes including regular and reverse von Kármán streets with various strengths, geometries, and Reynolds numbers (Re) by applying a smoothed von Kármán ...

Vortex streets in the earth's atmosphere

Pure and Applied Geophysics, 1967
Calculations of the Heisenberg parameter and Strouhal number, for mesoscale vortex streets in the atmosphere, support the analogy with the classical Karman vortex wake. Revised estimates of the horizontal coefficient of eddy diffusion are obtained.
