Abstract
The influence of corner shaping and turbulence intensity on the aerodynamic stability of square cylinders is studied with a quasi-static approach. Beside the sharp-edge corner condition, two different rounded-corner radii (r/b=1/15 and 2/15) are considered. The stability analyses are based on aerodynamic coefficients derived through static wind tunnel tests in smooth and turbulent flow, in the Reynolds number range between 1.7×104 and 2.3×105. The experimental data are employed to determine the stability boundaries depending on the angle of attack and – when relevant – on the Reynolds number.
