Determination of the discharge coefficient of a heavy hydraulic head slide gate

The results of a field and office study to determine the discharge coefficient (Cd) of a "sluice gate" of a water storage and intake system of a hydropower project are reported. In most hydropower projects, water is withdrawn from a dam built on a riverbed. Downstream of the dam the living...

In most hydropower projects, water is withdrawn from a dam built on a riverbed. Downstream of the dam the living conditions in the river are altered. To remedy this situation, mainly in times of low water, water is released from the dam in a controlled manner (ecological flow), usually by operating the sluice gate. In this context, the problem of the reservoir operators is related to the opening of the sluice gate that guarantees the ecological flow for a given level of the water in the reservoir. To solve this problem, the discharge downstream of the gate was measured for 3 gate relative openings (5%, 10% and 15%) and different water levels in the reservoir. With these data Cd values were found. The results show that tends to increase for openings smaller than 15%. This tendency could be influenced by the geometry of the lower lip of the gate.Se reporta los resultados de un estudio de campo y gabinete para determinar el coeficiente de descarga ( ) de una “compuerta desgravadora” de sistema de almacenamiento y captación de agua de un proyecto hidroenergético. En la mayoría de los proyectos hidroenergéticos, el agua se capta desde una represa construida en el cauce de un río. Aguas abajo de la represa las condiciones de vida en el río se alteran. Para remediar esta situación, principalmente en épocas de estiaje, se libera agua desde la represa de manera controlada (caudal ecológico) operando, usualmente, la compuerta desgravadora. En ese contexto, el problema de los operadores del embalse está relacionado con la abertura de la compuerta que garantice el caudal ecológico para un determinado nivel de agua en el embalse. Para abordar esta problemática, se midieron el caudal aguas abajo de la compuerta para 3 aberturas relativas de ésta (5%, 10% y 15%) y diferentes niveles de agua en el embalse. Con estos datos se hallaron valores de . Los resultados muestran que Cd tiende a aumentar para aberturas menores de 15%. Esta tendencia podría estar influenciada por la geometría del labio inferior de la compuerta.Universidad Nacional Mayor de San Marcos2020-12-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistasinvestigacion.unmsm.edu.pe/index.php/fisica/article/view/2031610.15381/rif.v23i3.20316Revista de Investigación de Física; Vol. 23 No. 3 (2020): 50th Anniversary of the EP of Mechanical Fluid Engineering; 66-71Revista de Investigación de Física; Vol. 23 Núm. 3 (2020): 50 Aniversario de la EP de Ingeniería Mecánica de Fluidos; 66-711728-29771605-7724reponame:Revistas - Universidad Nacional Mayor de San Marcosinstname:Universidad Nacional Mayor de San Marcosinstacron:UNMSMspahttps://revistasinvestigacion.unmsm.edu.pe/index.php/fisica/article/view/20316/16663Derechos de autor 2020 Bernardino Salvador Rojashttps://creativecommons.org/licenses/by-nc-sa/4.0info:eu-repo/semantics/openAccessoai:ojs.csi.unmsm:article/203162021-09-26T17:20:30Z
