Abstract

This paper aims to investigate the wave resonance in the WEC-breakwater gap of a dual-body hybrid system using the Star-CCM+ software. The effects of the narrow gap wave resonance on the performance of the dual-body hybrid system and the forces on the breakwater are studied. The influence of the WEC motion and the gap width of the hybrid system on the wave elevations are analyzed. Results reveal that the wave resonance in the WEC-breakwater gap significantly improves the wave energy extraction performance of the hybrid system, but has little impact on the wave attenuation performance of the hybrid system.
