Abstract: This paper describes the mechanics of flow over and through a Coanda-effect screen, a unique type of self-cleaning screen constructed from wedge-wire panels installed on supercritical slopes. The paper presents a numerical model for determining the flow rate through a Coanda-effect screen and discusses the variation of screen discharge capacity as a function of screen geometric parameters and the Froude number of the flow over the screen. The model was developed and calibrated using data collected in laboratory tests of several different screen configurations, and can be used to evaluate the hydraulic performance of custom designs, which should facilitate future application of Coanda-effect screens.
