Abstract

Based on the concept of space sharing and cost allocation, an integrated system combining oscillating buoy type wave energy converter and floating breakwater was proposed, and a coupled numerical model was established by computational fluid dynamics method, and the hydrodynamic characteristics of the integrated system was investigated, and the effects of power take-off （PTO） damping, the gap between wave energy converter and floating breakwater, the width of wave energy converter on the energy capture and wave attenuation characteristics of the integrated system were analyzed. The results show that the relative motion of the proposed integrated system is better than that of wave energy converter and stationary breakwater integrated system and the isolated wave energy converter. The reasonable selection of PTO damping coefficient can make the integrated system get better energy capture and wave attenuation performance. The reduction of the gap and the increase in the width of the wave energy converter can improve the energy capture characteristics of the integrated system, with the conversion efficiency up to 78.5%.
