Abstract

Abstract The free stream is usually turbulent in most practical applications. Most research, however, has been carried out in wind/water tunnels with low-level turbulence. A particularly strong effect of very low free stream turbulence is observed in three transition states of flow past cylinders. This means that the experimental data obtained in smooth flows cannot be used for practical flows without correction.
