Abstract

Abstract:

By using numerical simulation, the hydraulic parameters inclusive of pressure characteristic, velocity distribution and nappe form in slit-type flip bucket with curved surface were calculated and analyzed. What’s more, detailed information of flow field which cannot be acquired from physical models were obtained. This research serves as a guide for similar engineering.

Key words: slit-type energy dissipator, numerical simulation, pressure characteristic, velocity distribution, nappe form
