Abstract
Integrating a rectangular buoy type wave energy converter (WEC) inside the perforated caisson can be advantageous to the wave attenuation performance as well as the stability of the WEC. As a preliminary study on such integration system, a theoretical model was established to investigate the wave attenuation performance of the integration system with a fixed buoy inside a perforated caisson. The methods of separation of variables and eigenfunction function expansion were used to determine the velocity potentials in different fluid domains. Instead of the traditional linear pressure drop condition for perforated walls, a quadratic condition, which is more consistent with the practical truth, was used in this study. The proposed model was validated by results in a former research. The wave attenuation performance was then investigated and discussed through a parametric study.
