Harvesting Energy from Galloping Oscillations
The aim of this work is to exploit flow-induced vibration for energy harvesting. A cantilever beam carrying a tip mass in the form of a lightweight box having a square, triangular, or semicircular cross-section is designed to undergo galloping oscillations when subjected to an incoming wind stream. Electrical power is extracted from the self-excited flexural vibration of the beam through an ele...
متن کاملElectromagnetic energy harvesting from flow induced vibration
A new electromagnetic energy harvester for harnessing energy from flow induced vibration is developed. It converts flow energy into electrical energy by fluid flow and electromagnetic induction. A finite element model for estimation of the generated voltage of the energy harvester is developed. A prototype of the energy harvester is fabricated and tested. Experimental results show that an outpu...
متن کاملEnergy Harvesting from the Nonlinear Oscillations of Magnetic Levitation
This paper investigates the design and analysis of a novel energy harvesting device that uses magnetic levitation to produce an oscillator with a tunable resonance. The governing equations for the mechanical and electrical domains are derived to show the designed system reduces to the form of a Duffing oscillator under both static and dynamic loads. Thus, nonlinear analyses are required to inve...
متن کاملEnergy Harvesting from Axial Flow Induced Instabilities in Slender Structures
In this work we examine the prospects for harvesting energy from flutter instabilities of a slender, flexible cylinder in an axial flow stream. We couple the fluid-solid model and include energy harvesting as curvature based damping. In the first instance we model the reduced order system comprising of an articulated rigid cylinder pair with discrete springs and dampers and demonstrate the scop...
