Abstract
The aerodynamic behavior of a stationary rectangular 5:1 cylinder is the object of an international numerical and experimental benchmark study (BARC). In this paper, the unsteady characteristics of the high-Reynolds number flow past the cylinder was studied in the wind tunnel with pressure and force measurements on a sectional model in smooth and turbulent flows and with wake velocity measurements in smooth flow. The study is particularly focused on understanding the influence of the oncoming angle of attack and the oncoming turbulence properties on the mechanism of vortex shedding.
