摘　　要：文章提出一种带消波水道的方箱型浮式防波堤与振荡浮子式波浪能发电一体化装置概念设计方案,应用ANSYS Fluent软件,通过锚泊线准静态法、多体耦合动力学理论与Newmark-β法对一体化装置进行耦合水动力计算,分析不同阻尼及水道构型参数对集成系统消波与俘能效率的影响。结果表明,在阻尼选取区间内,线性等效电磁阻尼的俘能效率整体上大于Coulomb等效液压阻尼,增加浮子质量或增加线性阻尼系数,均可提升一体化装置的俘能效率,而对消波性能影响甚微。减小出口宽度,对俘能效率的提升有利并能提升消波性能。当消波水道入口完全浸没于水下时,俘能效率相对更高,消波效果更优。这种新颖的一体化装置构型为后续相关的消波与波浪能转换耦合水动力模型研究提供了思路与借鉴。The conceptual design scheme of an integrated device of a pontoon-type floating breakwater with a wave attenuation channel and an oscillating buoy wave energy converter is proposed.ANSYS Fluent software is applied and embedded with codes of multiple theories such as mooring line quasi-static theory,multi-body coupling dynamics theory and Newmark-βmethod,to realize the coupling hydrodynamic calculation of the integrated device.The effects of different damping and wave attenuation channel configuration parameters on the anti-wave and energy capture efficiency of the integrated system are analyzed.The results show that in the selected damping interval,the energy capture efficiency of the linear electromagnetic-equivalent damping is generally greater than that of the Coulomb hydraulic-equivalent damping.Increasing the mass of the buoy or increasing the linear damping coefficient can improve the energy capture efficiency of the integrated device,while has little effect on the wave attenuation performance.Reducing the outlet width of the wave attenuation channel is beneficial to the improvement of energy capture efficiency and can improve the wave attenuation performance.When the inlet of the wave attenuation channel is completely submerged in water,the energy capture efficiency is relatively higher,and the wave attenuation effect is better.This kind of novel integrated device configuration provides ideas and references for the subsequent relative coupling hydrodynamic model research on wave attenuation and wave energy conversion.
