摘要
To investigate wave energy extraction and wave attenuation performance of the "Nodding Duck" wave energy converter, a numerical model of regular wave interacted with the wave energy converter is developed using software Star-CCM+ of Computational Fluid Dynamics (CFD). The present numerical model is verified by comparing with published experimental results of the "Nodding Duck" wave energy converter. The resonance of the motion, energy conversion efficiency and transmission coefficient of this wave energy converter under different attack angles and wave height are investigated. Results indicate that the wave energy extraction and wave attenuation performance of the wave energy converter is improved significantly with the increase of the attack angle, and decreases significantly with the increase of the wave nonlinearity.
