Title:
ENERGY HARVESTING FROM FLOW-INDUCED VIBRATIONS
Document Type and Number:
WIPO Patent Application WO/2010/141830
Kind Code:
A3
Abstract:
Electrical energy is produced at a remote site by converting kinetic energy from fluid flow to electrical energy using a downhole harvesting apparatus. The downhole harvesting apparatus includes a vibrating sleeve member that vibrates in response to fluid flow through a tubular housing structure. The vibration of the sleeve is used to generate electrical power. The harvesting apparatus may include features to help maintain constant fluid flow in the tubular structure. The harvesting apparatus can be tuned to different vibration and flow regimes in order to enhance energy conversion efficiency.
