Comparison of Flow-Boundary Effects on Critical Submergence of an Intake

Abstract

In this study, the effects of canal bottom and dead-end wall on the critical submergence of a single rectangular or circular intake are investigated and compared. In order to find the functional relationship involving the critical submergence and the influencing dimensionless variables, dimensional analysis is utilized. Experiments were conducted on a rectangular or circular intake sited with different positions in a uniform canal flow. Experimental results have indicated that the flow boundaries considerably affect the critical submergence. The effect of the boundary cutting the free surface on the critical submergence is much larger than that of the sub-surface boundary not cutting the free surface.
