Abstract
In many applications, the adjustment of a gate opening to a specific value is crucial for the passage of a defined outflow or to maintain an upstream water level that serves upstream turnouts. Previous work used trial-and-error and interpolation methods to calculate the opening of sluice gates. This study concentrates on the development of a way to estimate the opening of sluice and radial gates to achieve the desired discharge or upstream water level. In addition to energy and momentum (E-M) principles, this paper develops relationships to determine the openings of sluice and radial gates under free- and submerged-flow conditions. Based on experimental data, the mean absolute relative errors for calculating the opening of sluice and radial gates under different flow conditions using the previously proposed methods, as well as dimensional analysis, were 4.3% and 7.1%, respectively. In this study, the calculated relative errors in employing E-M principles were reduced from 3.6% to 2.9%, in which the effects of energy loss were overlooked, and the gate’s energy coefficient was introduced.
