	1	Incident flow effects on the performance of piezoelectric energy harvesters from galloping vibrations显示文摘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 the objective of investigating the effects of upstream turbulence on the response of the harvester. The results show that both wake effects and upstream turbulence significantly affect the response of the harvester. Depending on the spacing between the two squares and the opening size of the mesh, wake and upstream turbulence can positively enhance the level of the harvested power.

	2	Piezoelectric energy harvesting from flexible delta wings显示文摘The potential for harvesting energy from a flexible delta wing using a piezoelectric bimorph is experimentally investigated.Different configurations of the proposed harvesting system were tested in a wind tunnel over a broad range of airspeeds.In addition to evaluating the level of harvested power,an analysis is performed to extract critical aspects for the relation between speed,flexibility,geometry and the potential power that can be harvested from a clamped,cantilevered flexible delta wing at low angles of attack and low speeds.This analysis provides an insight into parameters that impact energy harvesting from flexible membranes or elements.
