Abstract: In this study, critical submergence for an air-entraining vortex at intakes in a uniform canal flow was investigated. The potential flow solution for the combination of a point sink and a uniform canal flow is available, ...

Abstract: Vortex formation at intake is an important problem encountered in hydraulic engineering. When the submergence of the intake is not sufficient, air enters the intake by means of a free-surface vortex. The entrained air can ...

Abstract: In this study, the effects of intake-pipe blockage and location of impervious boundaries on critical submergence of an intake pipe are presented. Experiments were conducted on a horizontal intake pipe sited in a dead-end ...
