“…In contrast with horizontal beam in the wake of cylinder, the static (average) deformation in vertical beams has nonzero value. Since, in the SDOF used by Akaydin et al [38], the voltage is proportional to the displacement, this model predicts a nonzero value for the predicted average voltage, which is completely wrong. Hence, the SDOF model of Akaydin et al [38] cannot be used in numerical simulation of energy harvesting from vertical beams and, for these harvesters, the accurate algorithm should be used.…”

“…Thus, its numerical simulation should contain some solver for solving the governing equations of uid ow, piezoelectric material, and electric circuit. Akaydn et al [37,38] placed a piezoelectric beam in the wake of a circular cylinder for energy harvesting from uid ow. They used FLUENT software to simulate the threeway interactions of the turbulent ow, piezoelectric structure, and the harvester electronic circuit.…”

Abstract. Piezoelectric Energy Harvesting (PEH) of uid-ow energy has attracted signi cant attention throughout the last decade. In the previous PEH from uid ow, a piezoelectric beam was placed behind a blu body, such as circular cylinders. Hence, the piezoelectric beam oscillated due to the vortex shedding behind of the blu body. Subsequently, this vibration generated voltage in the beam. In many engineering vehicles such as airplanes, the strong vortex shedding caused by blu body was destructive and reduced the e ciency of devices; therefore; it was not proper to attach a blu body to these devices. In this paper, PEH from vertical beams in low speeds and high-speed ows is investigated. The current work shows that in contrast to low-speed ows, the extracted power from vertical beam in high-speed ows is considerable. Moreover, as a practical example of vertical beam in high-speed ows, the energy harvesting from piezoelectric Gurney ap attached to an NACA2412 airfoil is investigated. Finally, this study proposes a piezoelectric vertical beam with attached end cylinder as an energy harvester in the lowspeed ows. It is indicated that this device has strong vibration and, therefore, produces a remarkable electrical power.

ABSTRACTguidance, support and encouragement. He has been a great mentor and I have learned a lot from him, both in academic research and in personal life. He didn't only provide me the necessary infrastructure and resources to complete this project, but also gave me enough freedom and opportunities to test and implement my own ideas. He always encouraged me to think 'out of box' and allowed me to work on several other projects apart from the subject of this thesis. Prof. Priya has his own style; his dedication towards the work, his courage and conviction to take new challenges, his optimism, and the most importantly, his attachment with the students are few of the many qualities that has always inspired me and will always motivate me in future to move ahead.I would also like to extend my heartfelt gratitude to Prof. Walter O'Brien and Prof.Danesh Tafti for mentoring me in many academic courses and serving on my MS committee.

“…However, current wireless systems are mostly battery powered, which requires frequent replacements [3] and may pose environmental hazards when disposed. Therefore, clean, low-cost and labour-free, alternative sources of energy have been the subject of active research in the past decade, especially in order to power wireless devices, such as sensor networks for monitoring various systems [4,5]. Among various concepts, harvesting energy from vibrations has gained much attention (see for example, [4][5][6][7][8]).…”

Increasing environmental and energy concerns constitutes an encouraging development of future automobiles and autonomous vehicles that utilize cleaner and renewable energy. Although primarily an aerodynamic device, car rear spoilers experience various vibrations and limited attention has been given to exploiting these vibrations for generating alternative energy. This paper aims to investigate the potential of using the flow-induced vibration of rear spoilers on automobiles for energy harvesting. To that end, a fluid-structure interaction analysis of an inverted NACA 2408 spoiler behind an Ahmed body was undertaken. An Arbitrary Lagrangian-Eulerian flow solver was coupled to a non-linear structural dynamic solver using a commercial software application. The vibrations of the rear spoiler placed at 0, 50 and 100 mm below the top face of the Ahmed body under Reynolds number Re = 2.7 × 10 6 were simulated. It was found that the vibration of the rear spoiler at the highest elevation showed the largest amplitudes and strain, but the vibration of the rear spoiler at the lowest elevation offers an extended period of vibration before reaching a steady state. With the rear spoiler positioned at the highest elevation, a vibration frequency of 70 Hz and a steady-state principal strain of 350  may be achieved. These vibration levels compared well with previous investigation to sufficiently charge storage capacitors for wireless transmitters. The rear spoiler vibration may offer potential means for energy harvesting, and warrants further experiments under actual driving conditions.
