Abstract
Efficient estimation of energy harvesting performance in the pendulum-based galloping energy harvester is proposed and its validity is examined. In this estimation method, the power coefficient of the oscillating pendulum of the harvester is predicted based on measured torques of the steadily rotating pendulums. The predicted power coefficients were close to the power coefficients measured in oscillating pendulums. However, this estimation method does not perform properly in relatively low nondimensional flow velocities where the quasi-steady theory does not hold true.
