Design and Study Performance of Vibration-Based Mechanical Energy Harvester and Reservoir

This chapter investigates the potential of flow-induced vibrations, particularly transverse galloping, as a sustainable and efficient energy source. It presents a novel mechanical system that functions as both a rectifier and an energy converter, addressing the limitations of traditional energy harvesting methods. The system's design enables it to convert oscillatory motion into continuous rotation and store energy mechanically, enhancing overall efficiency. The chapter provides a detailed mathematical model of the system, including the forces and moments acting on its components, and derives expressions for its output work and electrical power. It also discusses the influence of various parameters, such as load resistance and bluff body diameter, on the system's performance. Furthermore, the chapter demonstrates the system's potential for small-scale energy harvesting, with a maximum output power of over 14 mW using a small-size bluff body at a wind speed of 5 m/s. The innovative design and comprehensive analysis presented in this chapter make it a valuable resource for those interested in advancing energy harvesting technologies and exploring new avenues for sustainable energy solutions.
