Study on Hydraulic Characteristics of the Dragon-Raise-Head Spillway Tunnel

Abstract:

This study compared the hydraulic characteristics of the Dragon-Raise-Head spillway tunnel by using a 3-D turbulence model, taking one specific spill tunnel reconstruction project as an example. In the first place, we proved the feasibility of the numerical stimulation results by the hydraulic model test of the Dragon-Head-Raise spillway tunnel comparatively. Then we comapared discharge capacity, head loss and flow state of four inlet elevations of the Dragon-Raise-Head spillway tunnel. The results showed little influence of different inlet elevations on discharge capacity, head loss and flow state under the premise of smooth curve section. The study would provide evidence for the design and optimization of the Dragon-Raise-Head spillway tunnel.
