Theoretical And Computational Design Analysis Of A Harmonica Type Aeroelastic Energy Harvester, Songkai Wang

All Theses

A wind energy harvester inspired by music playing harmonicas was proposed for micro-power generation. The energy harvester utilizes flow-excited self-sustained oscillations of a piezoelectric cantilever beam mounted in a wind pipe to generate electric power. The dependence of the energy harvester's power generation performance on a set of the design parameters such as the chamber volume, aperture width and beam dimensions has been studied previously. However, the performance of the nonlinear multi-physics system with two-way fluid structure coupling also depends on other design parameters such as the geometry of the oscillatory beam, the beam mounting configuration and the geometry of …
