摘要
将Smagorinsky亚网格模型引入ADCIRC潮流模型求解涡粘性系数,使模型在模拟近岸潮流方面更加合理。为进一步揭示中海油气开发利用公司广东沥青项目码头工程海域的潮流变化,利用改进的ADCIRC模型对湛江东海岛海域潮流场进行了合理地模拟和分析。结果表明该工程港池和进港支航道的开挖对湛江主航道影响很小。工程建设只改变了工程区海域的局部流态,并且新开挖航道的水动力条件有助于船舶顺流进港。
For more reasonable simulation of coastal tidal current, the Smagorinsky subgrid model is embedded into the ADCIRC model to get the horizontal eddy viscosity. For a further investigation of tidal current around the wharf of Guangdong asphalt project of Oil ＆ Gas Development ＆ Utility Co., CNOOC, the improved model is applied to simulate the tidal current in the coastal area near Donghai Island of Zhanjiang Bay. The result shows that the excavation of harbor basin and entrance channel has little influence to the main channel of Zhanjiang Port. The construction only changes the local flow pattern near the project, and the hydrodynamic conditions can help to the ships entered harbor.
