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 conical bluff body with a central axis, the conical bluff body fixedly attached to the elastic mount, the central axis of the elastic mount and the central axis of the conical bluff body being aligned, the conical bluff body being configured to generate vortex shedding when the elastic mount orients the conical bluff body in a flow-line traverse to a fluid flow and vibrates in response to the vortex shedding, wherein the conical bluff body comprises a permanent magnet or electromagnet; and a harvester coupled to the conical bluff body and aligned with the central axis of the conical bluff body, the harvester comprising a cylinder arranged outside of and aligned with the central axis of the conical bluff body, and a metallic coil circling a circumference of the cylinder, 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.
