The wake past a smooth cylinder perpendicular to the flow is studied 15D (cylinder diameters) downstream by using particle image velocimetry (PIV). Spatial shedding period is used to estimate the spatial Strouhal number (Sh) and to compare with time-resolved hot-wire anemometer (HWA). The vortices are detected within the spatial fluctuation field. The statistical vortex properties do not change within the explored range of Reynolds numbers (from 5 000 to 60 000), similarly the spectra and Sh. © Published under licence by IOP Publishing Ltd.
