... parameters (damping, stiffness) and Reynolds number (Re) are varied in the tests. The onset inflow velocity of oscillation is reduced and back-to-back vortex-induced vibration (VIV) and galloping is achieved, when placing interference cylinders in the vicinity of the basic oscillator. The interference due...

... vortex force and displacement of the VIV branch remains relatively constant. In the galloping branch, there are wake vortices in different directions that affect the cylinder's vibration every quarter of the vibration period, and the phase difference undergoes periodic large fluctuations (either in-phase...

... by the wake of the upstream cylinder. K 2 has a great influence on the harnessing power at higher velocities in the transition region from VIV to galloping and in galloping. Changing K 2 onsets and enhances galloping at lower flow velocity and harnesses up to 110% more energy than the case of K 1 = K 2...
