 Design and experiment of a double-wing wave energy converterWeixing Chen, Xiongsen Lin, Yunfei Lu, Shaoxun Li, Lucai Wang, Yongkuang Zhang and Feng Gao Renewable Energy, 2023, vol. 202, issue C, 1497-1506 Abstract: Considering the prospect to use marine energy to power ocean platforms, a double-wing wave energy converter suitable for power supply for them is proposed. Based on the mechanical structure and hydrodynamic parameters of the system, the frequency-domain dynamic model is established. According to the Cummins equation and the state space identification of the convolution term of the radiation force, the time-domain simulation of the system excited by wave is built. In addition, a 1:10 scaled prototype is manufactured and a tank experiment is carried out to study its performance. The accuracy of the simulation model is verified with the comparison between experimental and simulation results. The experimental results show that the power output of the prototype reaches 0.74 W under the regular wave with a period of 2.0 s and a wave height of 16 cm. Finally, adopting the similarity theory, the power output of the full-size system is calculated to be 2340.09 W. This study provides new ideas for solving the energy supply problem of ocean platforms.
