Abstract
Official abstract text for this publication.
The bluff body attaches to an elastic mount and is capable of generate vortex shedding when the elastic mount orients the bluff body in a flow-line traverse to a fluid flow and vibrates in response to the vortex shedding. A harvester is located within the bluff body and is capable of generating power above a specified threshold in response to the vibration.
First claim
Opening claim text (preview).
What is claimed is: 1 . An elastic bluff body, comprising: an elastic mount with a central axis; a substantially conical shaped bluff body with a central axis, the substantially conical shaped bluff body fixedly pivotally connected to the elastic mount, the central axis of the elastic mount and the central axis of the substantially conical shaped bluff body being aligned, the substantially conical shaped bluff body comprising a permanent magnet, the substantially conical shaped bluff body being configured to generate vortex shedding when the elastic mount orients the substantially conical shaped bluff body in a flow-line traverse to a fluid flow and vibrates linearly in response to the vortex shedding; and a harvester aligned with the central axis of the substantially conical shaped bluff body, the harvester comprising an iron rod and a metallic coil around the iron rod the harvester configured to generate power above a specified threshold in response to the vibration. 2 . The elastic bluff body of claim 1 , wherein the harvester vibrates at a resonance frequency of the elastic bluff body. 3 . The elastic bluff body of claim 1 , wherein the flow-line comprises a wellbore.
