Incident flow effects on the performance of piezoelectric energy harvesters from galloping vibrations
Theoretical and Applied Mechanics Letters
In this paper, we investigate experimentally the concept of energy harvesting from galloping oscillations with a focus on wake and turbulence effects. The harvester is composed of a unimorph piezoelectric cantilever beam with a square cross-section tip mass. In one case, the harvester is placed in the wake of another galloping harvester with the objective of determining the wake effects on the response of the harvester. In the second case, meshes were placed upstream of the harvester with thedoi:10.1063/2.1402202 fatcat:qfyw6eiafjdxfd7sekyv6hizze
