Flow-induced Vibration (FIV) involves stable or unstable motion of the body due to two-way coupling of body motion and fluid flow. Five cylinders are arranged at a sinusoidal formation and they can move as a unit while elastically mounted. Five cylinders are of equal diameter. The Reynolds number of the flow is fixed at 150. The horizontal and vertical spacing from the center of the cylinder to the next cylinder are 4.0 and 3.0. The amplitude of vibration increases as the damping of the system reduces. Highest amplitude shifted to higher reduced velocity with increasing damping. The power can be harvested through the motion of the body. Maximum average power is shifted to lower reduced velocity. Maximum extracted power is observed to be 1.5 and 3 times than the tandem cylinder and single cylinder power output.

摘要

Flow-induced Vibration (FIV) involves stable or unstable motion of the body due to two-way coupling of body motion and fluid flow. Five cylinders are arranged at a sinusoidal formation and they can move as a unit while elastically mounted. Five cylinders are of equal diameter. The Reynolds number of the flow is fixed at 150. The horizontal and vertical spacing from the center of the cylinder to the next cylinder are 4.0 and 3.0. The amplitude of vibration increases as the damping of the system reduces. Highest amplitude shifted to higher reduced velocity with increasing damping. The power can be harvested through the motion of the body. Maximum average power is shifted to lower reduced velocity. Maximum extracted power is observed to be 1.5 and 3 times than the tandem cylinder and single cylinder power output.
