| Abstract: | Designing and variety of throw flow nose ridge are very flexible. In consideration of features of throw flow nose ridge of spillway in Zipingpu project, this paper adopts CFX software to improve the shape of throw flow nose ridge. The optimization is testified through model test. It is shown that distribution of flow on throw flow nose ridge is symmetrical and the throw distance is far, moreover, the downriver irruption is shallow. |
