Velocity profiles in a free-surface flow system with a hydraulic rotational vortex
Free-surface flow system are characterized by the exposure of an area to the atmosphere. The flow velocity in these systems is conditioned by factors such as the roughness of the materials which forms the section that produces friction forces opposed to the fluid movement.

| description | Free-surface flow system are characterized by the exposure of an area to the atmosphere. The flow velocity in these systems is conditioned by factors such as the roughness of the materials which forms the section that produces friction forces opposed to the fluid movement. The purpose of this study is to provide an overview of the distribution of velocity lines in a free-surface flow (channel) which includes a hydraulic rotational vortex. Gauging and velocity were measured in nine sectors of the experimental flow system; seven were set in the section of the channel that feeds the prototype and two in the rotational vortex. Flow velocities were taken with the Pitot tube at various points along each sector. Velocity distributions were made with the aid of a computer application for data interpolation and were tested through a computational-fluid-dynamics (CFD) method. The results obtained allowed to visualize the flow’s maximum velocities location in the sections of the channel and the rotational vortex; and to check the flow’s velocity variation in accordance with the gradual changes of the dimensions and features in each driven section. In addition, a significant increase of fluid velocities when producing the rotational and vortex flow was observed. |

Los sistemas de flujo a superficie libre se caracterizan por la exposición de una región del fluido a la atmósfera. La velocidad de flujo en estos sistemas está condicionada por factores como la rugosidad de los materiales que conforman la sección que producen fuerzas de fricción que se oponen al movimiento del fluido. El propósito de este trabajo es el proporcionar una visión general de la distribución de las líneas de velocidad en un flujo a superficie libre (canal) que incluye un vórtice rotacional hidráulico. El aforo y toma de velocidades se realizó en nueve sectores del sistema de flujo experimental; siete sectores se fijaron en la sección del canal que abastece el prototipo y dos sectores en el vórtice rotacional. Las velocidades del flujo se midieron con el tubo Pitot en varios puntos en cada sector. Las distribuciones de velocidad se elaboraron con el apoyo de una aplicación informática para interpolación de datos y se comprobaron mediante un sistema de Dinámica de Fluidos Computacional-CFD. Los resultados obtenidos permitieron visualizar la localización de las velocidades máximas del flujo en las secciones del canal y del vórtice rotacional; y, comprobar la variación de la velocidad del flujo de acuerdo a los cambios graduales de las dimensiones y características de cada sección de la conducción. Además, se observó un aumento significativo de la velocidad del fluido cuando se produce el flujo rotacional y vorticial.Escuela Superior Politécnica Agropecuaria de Manabí Manuel Félix López2018-06-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistasespam.espam.edu.ec/index.php/Revista_ESPAMCIENCIA/article/view/149Revista ESPAMCIENCIA; Vol. 9 Núm. 1 (2018): REVISTA ESPAMCIENCIA 2018; 33-421390-8103reponame:Revistas Escuela Superior Politécnica Agropecuaria de Manabíinstname:Escuela Superior Politécnica Agropecuaria de Manabíinstacron:ESPAMspahttps://revistasespam.espam.edu.ec/index.php/Revista_ESPAMCIENCIA/article/view/149/131info:eu-repo/semantics/openAccess2025-02-25T14:35:20Zoai:ojs.pkp.sfu.ca:article/149Institucionalhttp://revistasespam.espam.edu.ec/Universidad públicahttp://www.espam.edu.ec/http://revistasespam.espam.edu.ec/oai.Ecuador.1390-81031390-597Xopendoar:02025-02-25T14:35:20Revistas Escuela Superior Politécnica Agropecuaria de Manabí - Escuela Superior Politécnica Agropecuaria de Manabífalse |
