| 摘 要： | 建立了一个基于σ变换和内外模式分裂技术三维水流数学模型，采用有限节点法（平面）和变步长差分法（σ向）对方程进行了离散；通过风生流和环岛水流两个理论模式对所建模型进行了校验，并将该模型应用到杭州湾的三维水流数值模拟中，效果良好，所建模型垂向分辨率高，简单实用，可应用于河口，海岸，湖泊等大范围水域的水流数值计算。 |

| Abstract: | A 3D numerical model is established based on coordinate transformation and process splitting techniques; a finite node method is applied to the horizontal discretion; and difference methods with variable vertical steps are applied to the vertical discretion. The model is corrected by both wind flow and annular flow theories, and then well verified by the site values of Hangzhou Bay. During the 3D numerical simulation, the model is found of high vertical precision as well as easy understanding and programming. It can also be applied in the study of other water zones such as estuaries, coasts, and large lakes. |
| Keywords: | D numerical flow model coordinate transformation process splitting method finite node method variable-step difference method Hangzhou bay |
