Özet
In this study, vortex sheddings from cylinders of circular and rectangular cross-sections of finite length which spanned the mid-height of the test section of a horizontal wind tunnel, were determined experimentally. Three rectangular models having width-to-height ratios of 0.5, 1.0 and 2.0 were considered. Hot-film measurements in the wake of these models were carried out at Reynolds numbers in the range 1\times104-2\times105. From these measurements, spectral density distributions depending on model¹s width-to-height ratio, blockage, angle of incidence and Reynolds number in the wake were determined.
