Abstract
The aeroelastic instability starting at low reduced flow speed due to the interference between vortex-induced vibration (VIV) and transverse galloping was studied in the wind tunnel in the case of an elastically-supported slender rectangular cylinder with a side ratio of 1.5 and the short side face perpendicular to the flow. The tests were carried out in a wide interval of Scruton numbers and particular attention was devoted to the range in which VIV and galloping excitation mechanisms tend to decouple, and to the effects of free-stream turbulence.
