Summary
There is experimental evidence that the appearence of discontinuities in the Strouhal number Reynolds number range 50–160 depends on the cylinder boundaries and the aspect ratio. The discontinuity at Re ≈ 90 observed by Tritton [22] is therefore a three-dimensional effect. The discontinuities in the Strouhal number are accomplished by sudden changes in the shedding angle and by vortex splitting. The discontinuities and slanted shedding disappear if the cylinder boundaries are decoupled from the rest of the cylinder by using “end-cylinders”. Furthermore, the base pressure and velocity profiles of the wake near an end plate are presented.
