Abstract: A 2D-3D combining turbulent model with complicated boundary is developed, in which some new techniques are used to treat the free surface and boundary condition. The important hydraulic parameters of flow field is obtained with this model. The results are more reasonable than thadw traditional models. In the traditional models, some parameters such as pressure cannot be obtained in 2D simulation and exact free surface is difficult to be obtained in 3D simulation, since 2D and 3D turbulent flow fields are simulated separately. The model has been used to simulate the flow field of the diversion open channel of THREE-GORGE-PROJECT. The numerical results are verified by the actual measurement and adopted by the construction authority in choosing the navigation route of the diversion open channel.
