Investigation of a Sill Effect on Rectangular Side-Weir Flow by Using CFD

Abstract

Side weirs are water intake or discharge structures that discharge water from, e.g., a dam, an open channel to external environment for using flow control, or irrigation system. In this paper, to examine how the sill placed in different locations of the main channel effects a side-weir discharge performance, a three-dimensional (3D) computational fluid dynamics (CFD) model together with experimental results were used. In the numerical simulations,
