| 聚焦于山东省昌邑市三峡300MW海上风电融合试验示范项目,探讨海上风电场(Offshore Wind Farm: OWF)与海洋牧场的融合发展新模式。以该项目为背景,我们在海上风电设施周围布设人工鱼礁,以实现海洋风电与海洋牧场的有机结合。本研究利用计算流体动力学(CFD)建立了海上风电场中人工鱼礁的流场效应水动力模型,并通过Fluent数值模拟对海上风电桩基与人工鱼礁周围的流场效应进行了深入研究。我们通过改变人工鱼礁的投放规模、纵向(T/L)和横向距离(P/L)以及空间布局等因素,系统地研究了在不同工况条件下,人工鱼礁与桩基周围流场效应的变化。结果表明增加G/D和P/L可增强上升流效果,同时减少剪切力的不均匀分布。T/L较大时,剪切力分布趋于均匀,但可能导致局部背涡流增强,对结构稳定性产生影响。通过本研究,我们能够深入理解海上风电与人工鱼礁相互作用的动态过程,并为未来海洋风电和海洋牧场融合发展提供科学依据。这一融合模式的探索有望为我国海洋资源的可持续利用和海洋生态系统的保护提供新的思路和方法。 |

| Abstract: |
| Focusing on the 300MW offshore wind power integration pilot demonstration project by Three Gorges in Changyi City, Shandong Province, this study explores a new model for the integrated development of Offshore Wind Farms (OWF) and marine ranching. Using this project as a backdrop, artificial reefs were deployed around the offshore wind facilities to achieve the organic integration of offshore wind power and marine ranching. This research utilizes Computational Fluid Dynamics (CFD) to establish a hydrodynamic model of the flow field effects of artificial reefs within the offshore wind farm, with in-depth analysis conducted through numerical simulations using Fluent. By varying factors such as the deployment scale of the artificial reefs, longitudinal (T/L) and lateral spacing (P/L), and spatial arrangement, we systematically studied the changes in flow field effects around the reefs and wind turbine foundations under different conditions. The results indicate that increasing G/D and P/L can enhance the upwelling effect while reducing the uneven distribution of shear forces. A larger T/L leads to a more uniform distribution of shear forces but may enhance local back eddies, potentially impacting structural stability. This study provides a deeper understanding of the dynamic interactions between offshore wind turbines and artificial reefs and offers scientific guidance for the future integrated development of offshore wind farms and marine ranching. The exploration of this integration model is expected to provide new approaches and methods for the sustainable utilization of marine resources and the protection of marine ecosystems in China. |
