 Mathematical modeling of a submerged piezoelectric wave energy converter device installed over an undulated seabedVipin V. and Santanu Koley Renewable Energy, 2022, vol. 200, issue C, 1382-1392 Abstract: A piezoelectric wave energy converter (PWEC) device integrated with an impermeable breakwater placed over an undulated seabed is considered. The PWEC device is composed of a single submerged flexible plate with piezoelectric layers attached to both faces of the flexible plate. Due to the piezoelectric effect, this piezoelectric plate generates electricity when excited by the incident waves. A detailed analysis is done to investigate the effect of PWEC plate submergence depth, plate length, plate edge conditions, incident wave period, bottom ripple amplitude, and ripple number on the power generation by the PWEC device. It is seen that the PWEC device edge conditions, submergence depth, and plate length play a significant role in the resonating pattern associated with the wave power generation curve. The results demonstrate that the PWEC device having moderate plate length and with free and moored type front edges generates a higher amount of wave power for a wider range of incident wave frequencies.
