Abstract

Computational Fluid Dynamics (CFDs) analyze software package programs recently gained a high importance in hydraulic engineering. The present study investigates how the different sills will affect the flow dynamics in free-surface flows. 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 for each selected location.
