General note The current method of producing energy from non-renewable sources may soon come to an<br/>end due to the ever-increasing demand for fossil fuels and the implications of escalating<br/>global warming. For microelectromechanical systems that only need a few watts of power to<br/>operate, an energy harvesting method based on wake flow energy is suggested. When a<br/>piezoelectric flag is employed as a cantilever beam and positioned in the wake of a bluff<br/>body, the strain exerted in the eel and the electrical voltage generated are ample to operate<br/>underwater sensors. The goal of this research is to present an efficient, simple, and resilient<br/>energy harvester that uses flow generated oscillations in response to ambient flow and fluidstructure interaction of flexibly mounted piezoelectric eel (pivoted mechanism) with inverted<br/>c-shape cylinder. Research objectives are to study the effect of spring stiffness and Gz (Gap<br/>along z-axis) on energy harvesting with varying Velocity. It was concluded from the research<br/>that by increasing the spring stiffness Ks i.e., 0.005-0.07 N/mm, velocity from 0.18m/s to<br/>0.36m/s at Gz = 6 results in highest frequency of 0.0887Hz, amplitude to length ratio of<br/>1.4361, and maximum amount of output power 9.25uW.Minimum values were obtained at<br/>bottom level of flow at Gz = 10, lower spring stiffness i.e., Ks=0.005 N/mm and lowest flow<br/>velocity of 0.18 m/s. While comparing the results with previous studies i.e., Circular, and<br/>inverted c-shape cylinder with mechanism of non-pivoted flag, significant amount of<br/>increment is observed in flapping frequency, amplitude to length ratio and output power<br/>which is 5.47%, 34.13% and 61.12% respectively.
