| 中文摘要: |
| 在采用拟合曲线网络系统模拟天然河道边界基础上，建立了符合弯道(含急弯河道)水流特性的贴体坐标系下三维数学模型，并针对弯曲河段可能引起的回流及环流，引入双方程κε紊流模型精细模拟，经长江某急弯河段的实例计算，取得较为理想的效果。 |
| 英文摘要: |
| A 3-D mathematical model in body-fitted curvilinear grid system, that conforms to the characteristic of flow in river bend is established. The k-εturbulence model is applied to simulate the flow detail. The availability of the model is examined by the calculation of the flow in a river bend of Yangtze River. The results show that the model is effective and satisfied. |
