Numerical modelling of sluice gates with different sill types under submerged flow conditions

Abstract

A B S T R A C T ComputationalFluid Dynamics (CFDs) analyze software package programs recently gained a high importance in hydraulic engineering. The present study investigates how different sills will affect in terms of flow dynamics. In the study, velocity contours and velocity magnitudes for each sill shapes are investigated. The velocity magnitudes are compared by taking 4 cross-sections from the downstream region. Results showed that sills located at downstream of the channel decrease the velocity magnitude at per selected location. Thereby it was concluded that the sill usages could protect the channel bottom from the cavitational and scouring damages due to high flow velocities. In this respect the study will help to the hydraulic designs in this scope.
