Abstract Flow visualizations and surface pressure measurements are performed to study the branching phenomenon of a horseshoe vortex upstream of a series of rectangular cylinders with aspect ratios ranging from 0 to 17. The Reynolds numbers are 500 for visualization experiments and 1990 to 6650 for wind tunnel surface pressure measurements. The flow visualization results indicate that a horseshoe...
AbtractExperiments were performed for individual realizations of the vortex shedding process behind a circular disk at Reynolds numbers of 103105, at which periodic vortex shedding prevails in the wake. The phase differences regarding the individual vortex shedding structures detected at multiple circumferential locations in the wake were obtained by analyzing the hot-wire signals with a conditional-sampling...
