Description

In this research, we discuss the possibility to scavenge energy from fluid including turbulence. Based on mechanism of turbulence, energy scavenging devices are expected to keep nonlinearity for accepting wide band spectrum distribution of turbulence. A magnetoelastic beam is adopted as an energy scavenging device. This magnetoelastic beam is excited in magnetic field consisting of two magnets. In this report, the potential shape, which governs the dynamics, is discussed from the view point of the field arrangement. We also estimate the possibility of energy scavenging through synchronization. We analyze energy exchange between two synchronized systems and find some similarities with resonance.
