Summary

Purpose of this work is to describe the results obtained in a wind-tunnel on a model consisting of two cylinders, one in the wake of the other, with both fixed or with the downstream cylinder allowed to vibrate.

The fundamental characteristics of the fluid in the wake and the forces acting on the downstream cylinder are also reported. The value of energy introduced by the fluid on a vibrating cylinder in the wake is also determined.

Sommario

Vengono riportati i risultati sperimentali ottenuti in galleria del vento su un modello costituito da due cilindri, di cui uno è posto in scia dell'altro, nei casi in cui siano entrambi fissi o che il cilindro in scia possa vibrare.

Sono pure riportate le caratteristiche fondamentali del fluido nella scia e le forze che agiscono sul cilindro a valle. Nel caso in cui il cilindro in scia possa vibrare viene pure riportato il valore dell'energia introdotta dal fluido.
