Abstract

To improve our understanding of structural stability, two vibrating tandem square cylinders is numerically investigated in the present study. In reattachment regime (L* = 2), mass ratios (m* = 3), Reynolds numbers (Re = 100) are considered. Different branches are identified. For the first cylinder, the maximum A* is about 0.10, which is one-third of a single cylinder. For the second cylinder, the maximum A* is about 0.42, which is 1.45 times of a single cylinder. Wake mode is observed, and the existence of the second cylinder restrains the vortex shedding from the first cylinder.
