Abstract: (3773 Views)
In this paper, the governing equations of sea waves are analyzed nonlinearly and the energy extraction from the waves in the Lark and Faror islands in the Persian Gulf is determined. According to the data in the last 31 years, the waves of these two islands have the most incidence for the height of 0-0.4 m and 0.4-0.8 m corresponding for the time periodicity of 2.4-3 s and 3-3.6 s, respectively. Therefore, waves with an average period of 3 s and a height of 0.5 m are used in the design process. The Cylindrical Energy Transfer Oscillatory (CETO) mechanism is chosen and the conceptual design is carried out with an in-house FORTRAN code, in which the results are in favorable agreement with the available experimental data. Investigations show that optimum power production requires the range of 2.8 to 3.2 for the ratio of the height to the radius of the buoy. Also, it is possible to access 25 kW power for each mechanism in the optimum conditions.
