数值模拟方法是研究河口海岸环境问题的理想工具之一.但由于河口区域的海岸线与河岸线的形状非常复杂,加上众多的岛屿,给模式网格的划分造成很大的困难。为此,将自适应网格的生成方法应用于长江口和杭州湾的水动力学模拟,较好地克服了均匀网格拟合边界的困难,得到了较合理的计算结果.
The numerical simulation method is one of the ideal tools for studying the estuarine and coastal environment, but due to the complex shape of the coastline and river shoreline in estuarine areas and the large number of islands, it is very difficult to divide the pattern grid. Therefore, the adaptive mesh generation method is applied to the hydrodynamics simulation of the Yangtze Estuary and Hangzhou Bay, which overcomes the difficulty of the uniform mesh fitting boundary well and obtains a more reasonable calculation result.
