STUDY OF HYDRAULIC JUMP CHARACTERISTICS IN A LABORATORY OPEN CHANNEL

Evangelos Keramaris, Y. Loukas, G. Droulias

Abstract

This study investigated the characteristics of hydraulic jump in open channels. Laboratory experiments were performed on a rectangular channel with different discharges, different sluice gate heights, and different weir heights. The mea-surements of a wide range of water depths and heights along the channel were used to calculate various coefficients of hydraulic jump, and energy loss before and after the hydraulic jump through known hydraulic formulas and equations, and Froude number for each gate height. Similar experiments were carried out on rectangular and other cross sections and the diagrams of these experiments were studied for various magnitudes. The results showed a wide range of Froude numbers, as well as varying energy loss values in each utility measured. © 2021 Begell House Inc.. All rights reserved.
