Abstract
The Strouhal number for the vortex shedding from a circular cylinder mounted normal to the freestream is shown in Fig. 1 as a function of Reynolds number. The experimental results19 define a unique Strouhal number (within the data scatter) only for Re 3.5xl06. Until Roshko showed otherwise,1 it was generally believed that the periodic von Karman-type vortex street could not exist at supercritical Reynolds numbers. Roshko showed that the harmonic vortex shedding reappeared at /te>3.5x!0 6, with a shorter wavelength, higher frequency. These results were confirmed later by Jones et al.,2 who also found that the harmonic vortex shedding started at Re>3.5xlQ6. The various nonunique harmonic results in the transcritical region
