Many initiative exist in the wave energy device developments. However, it is still a young area in terms of long-term practical utilization. Evans (1981) and Falnes (2002) provides extensive descriptions on theoretical calculations of wave energy extraction. Recent detailed reviews by Falnes (2007) and Falc˜ao (2009) also describe the development in the area of wave energy devices.
Herein, hydrodynamic analytical estimates of the WavePiston system to generate flat plate data are presented.
The energy contribution of non-linear wave forces on the moving plates of the WavePiston are considered for two non-linear waves and two plate sizes. First the wave theory used will be introduced and the method to solve the problem will be explained. In the end the results will be discussed, recommendation to further analysis will be given and some main concerns about the construction of the WavePiston is mentioned.
The present investigations have been conducted during four weeks, January, 2010.
