Abstract: In this study, the critical submergence for a rectangular intake in a uniform canal flow is investigated. The potential solution for the combination of a line sink and a uniform flow is available and known as Rankine ...

Abstract: The critical submergence for a group of multiple pipe intakes is predicted using a “superposition method” based on a potential flow solution. Experiments on groups of two, three, and four intakes were conducted. Experimental ...

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: A convective flow is generated in the sidearm of a lake due to surface cooling. In this paper, steady, incompressible, and 2D flow in a horizontal sidearm having constant width is analyzed. The vertical acceleration terms ...

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 ...

Abstract: The critical submergence for dual rectangular intakes with no partition walls was investigated. To predict this critical submergence, the same principles as the available superposition methods developed for multiple pipe ...
