Interference Effect of Downstream Strip Plate on the Crossflow Vibration of a Square Cylinder

Interference Effect of Downstream Strip Plate on the Crossflow Vibration of a Square Cylinder

Wind tunnel experiments are carried out to investigate interference effect of downstream strip plate of width w=d on the crossflow vibration of a square cylinder with a side length d=26mm. While sufficient suppression of Karman vortex induced vibration is not attained by plates with crossflow height...

Zusammenfassung:Wind tunnel experiments are carried out to investigate interference effect of downstream strip plate of width w=d on the crossflow vibration of a square cylinder with a side length d=26mm. While sufficient suppression of Karman vortex induced vibration is not attained by plates with crossflow height less than ld=4d, the galloping is suppressed even by a square plate, i.e. ld=d, when the gap ratio 1
