Abstract

CASTELLANOS, Hermes E; COLLAZOS, Carlos A; FARFAN, Javier C  and  MELENDEZ-PERTUZ, Farid. Design and Construction of a Hydraulic Channel of Variable Slope. Inf. tecnol. [online]. 2017, vol.28, n.6, pp.103-114. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642017000600012.

In this article the design, construction, calibration and validation through experimental assays using a hydraulic channel of variable slope, is presented. This device is part of the Hydraulics Laboratory of the University Manuela Beltrán, campus Cajicá in Colombia. The experimental setup consists of a structural aluminum support of 5m long, a hydraulic bench of 250 liters, a rectangular acrylic channel of 5 meters long, and low-cost flow and pressure sensors. As a novelty, and different from other similar laboratories, a hydraulic system which was coupled to a pressure sensor for recording pressure changes in different areas of the channel with a higher degree of accuracy was included. This tool will provide the necessary support to students, teachers and researchers in the fields of hydraulics, environmental engineering and related areas. Finally, performance validation of the channel was provided by the successful reproduction of experiments proposed in the literature.

Keywords : open channels; variable slope; free edge; caudal; pressure; flow; specific energy; laminar flow.
