Numerical simulation and experimental study on the characteristics of slit-type energy dissipater in high arch dam

CHEN Hua-yong,XU Wei-lin,DENG Jun,LI Nai-wen (Sichuan University,Chengdu 610065,China)  
The standard k-ε two-equation model for turbulent flow with VOF method was applied to simulate the important hydraulic factors such as pressure distribution in the discharge tunnel and on the wall of slit-type energy dissipater, water boundary profile, velocity distribution, water entry angle, and hydrodynamic pressure on the bottom of plunge pool. The results of numerical simulation were in good agreement with experimental data. Additionally, projectile motion theory was employed to calculate the track of water motion, angle of incidence in different conditions, which could overcome the shortage of flow velocity measurement in physical models.
