Abstract
The effects of wave resonance in the narrow gap on the integrated system consisting of a dual floating body oscillating wave energy converter (WEC) and a floating breakwater are studied. A two-dimensional numerical model is established using the viscous computational fluid dynamics software Star-CCM to simulate the interaction between waves and a dual floating body/ floating breakwater-type wave energy device. Wave energy conversion performance, wave attenuation performance, wave surface elevations in the gap between floaters, and the effects of wave resonance on the performance of the device are analyzed. The influences of WEC motion and the gap between floaters on the narrow gap resonance frequency and wave elevation are also studied. Results show that the wave energy conversion efficiency of the dual floating body/floating breakwater-type wave energy device is significantly improved due to the wave resonance in the narrow gap. The wave resonance frequency in the narrow gap decreases with the gap between the floaters and the WEC draft increases. Moreover, the wave elevation in the narrow gap increases with decreasing WEC width.
