| 聚焦于山东省昌邑市三峡300 MW海上风电融合试验示范项目, 本文探讨海上风电场与海洋牧场的融合发展新模式。基于该项目背景, 研究在海上风电设施周围布设人工鱼礁, 以实现海上风电与海洋牧场的有机结合。利用计算流体动力学建模并通过Fluent数值模拟, 对海上风电单桩基础与人工鱼礁周围的流场效应进行了详细分析。研究通过改变人工鱼礁的投放规模、鱼礁与桩基的距离(G/D)、礁体间纵向距离(T/L)、礁体间横向距离(P/L)以及空间布局, 系统考察了不同工况条件下, 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可显著增强上升流效果, 并减少剪切力的不均匀分布。较大的T/L有助于剪切力的均匀分布, 但可能导致局部背涡流增强, 进而影响结构的稳定性。 |

| Abstract: |
| Focusing on the Three Gorges 300 MW offshore wind power integration pilot project in Changyi, Shandong Province, this study explores a novel model for integrating offshore wind farms with marine ranching. This study investigates the types of artificial reefs deployed around offshore wind turbine foundations to enhance the synergy between wind power generation and marine ranching. Using computational fluid dynamics and fluent numerical simulations, this study analyzes the impact of flow fields around offshore wind turbine foundations and artificial reefs. It examines the influence of varying configurations, such as the scale of artificial reefs, the distance between foundations (G/D), and the longitudinal (T/L) and lateral (P/L) spacing between reefs, on flow dynamics. The findings indicate that increasing G/D and P/L considerably enhances upwelling and reduces uneven shear stress distribution. In contrast, larger T/L improves shear stress uniformity but may increase local wake vortices, potentially affecting structural stability. This study deepens the understanding of the dynamic interactions between offshore wind turbines and artificial reefs, providing scientific guidance for the integrated development of offshore wind farms and marine ranching. The proposed integration model offers new insights and approaches for the sustainable utilization of marine resources and ecosystem conservation in China. |
