Discharge Coefficient for Siphon Spillways
Publication: Journal of Irrigation and Drainage Engineering
Volume 139, Issue 3
Abstract
The study deals with the discharge coefficient for siphon spillways based on the results of experimental methods and numerical simulations. Siphon spillways are used as the outlet in reservoirs to control the incoming flood flows. A scaled plexiglass model of a siphon was fabricated and tested in the laboratory flume to determine the siphon discharge coefficient over a range of Reynolds numbers. The RNG model was used to obtain the discharge coefficient of the siphon. The existing experimental results and the present test data were used to validate the model predictions. The agreement of the model with test data was reasonable. A properly validated model permits the evaluation of the siphon discharge coefficient for different flow configurations encountered in the field, without recourse to expensive experimental procedures.
