... of the lock-in regime varies following Re, m* and . For high m*, the vibration divide into three branches, initial branch, low branch and desynchronization branch. For low m*, the new branch, upper branch, can be observed. Cylinder clusters are generally used in marine risers, high-voltage transmission lines...

...-flow, categorizing numerical as well as experimental studies. Generally, the flow regime around two cylinders can be categorized according to the positioning of both cylinders relative to each other (tandem, side-by-side and staggered), the ratio of gap-width to diameter (gap ratio G/D) and the overall...

... and a wide range of rotation rate from 1.6 to 6. Rotation rate is the ratio of the rotational speed of the cylinder surface to the incoming fluid velocity. It is found that increasing rotation rate beyond a critical value results in transition from no vortex shedding regime to secondary instability regime...

To study the relationship between local centre-to-centre separation and shedding regimes in tandem arrangements, extensive experiments (Zdravkovich, 1977; Igarashi, 1981) and computations (Meneghini, 2001) had been conducted. Those studies indicated that the occurrence of the bi-stable depended on L/D...
