CFD study on the correlation for a partially submerged orifice flow

The purpose of this study is to develop a CFD model that allows the correlation study for a partially submerged circular orifice flow in open channel. Three phenomena driven by gravity were included in this study, which are free discharge orifice (Case A), partially submerged orifice flow in downstr...
