Flip trajectory buckets are widely used in hydraulic engineering. With the rapid development of water conservation projects, an increasing number of these projects are located in complex topography. As a result, the energy dissipation and anti-scour abilities of the outlet structures in such projects have become the focus of research. This study used FLOW-3D fluid computation software with a renormalization group turbulence model and a volume of fluid free surface tracking technique. The bank of the ShiZiYa reservoir is steep and is located in a narrow river valley, in which the downstream angle is approximately 70°. The system was modeled under the conditions of this special terrain with the flow energy dissipation scheme having dovetail drainage characteristics, and the results were verified experimentally. With adjustments of the angles of the left and right walls, the width and jet angle of the dovetail-shaped sill were optimized in the model to ensure that the downstream flow fell into the main channel, and the hydraulic characteristics of the water jet were analyzed. The results showed that this scheme can meet the flood safety requirements of the ShiZiYa reservoir. View Full-Text
