FLOW-3D MODEL: THEORY, VERIFICATION AND APPLICATION TO SIMULATE SIPHON SPILLWAYS

Abstract

This paper introduces the Flow - 3D model and simulations of siphon spillways in reservoirs. The model theory and model applications in hydraulics are presented. The physical experiment to verify the Flow - 3D model shows that the model works well for the case of siphon spillways. Consequently, the model is used to simulate the Hadong siphon spillway. The research results show the outstanding characteristic of the siphon spillways that the negative pressure occurring in the siphon makes it working. The Flow - 3D model and the siphon spillways can be applied to investigate hydraulics in Vietnam.
