AbstractA novel design of a hybrid piezoelectric-electromagnetic harvester for vortex-induced vibration applications inside a pipe-flow is proposed. The piezoelectric energy harvester is modeled with a macro-fiber composite with an electromagnetic oscillator. Analytical and numerical models were developed for the fluid-structure interaction. An optimization study was conducted using finite element modelling across different bluff body shapes and orientations where triangle and 2.5x ellipse were optimal choices for maximizing energy harvesting properties. An investigation into dual-mass energy harvesting was also performed for bandwidth enhancement. A secondary beam has improved the piezoelectric performance by 21% to 52%. Finally, an experimental study was conducted to verify the narrowband resonance models and validate the use of a magnetically coupled dual broadband harvester (58% enhancement). Optimization and design of the harvester has led to improvements in performance that can realize powering sensors and devices in wireless applications.
