Resumen:
In this paper the design of a structure to dissipate energy in the spillways was analyzed as an alternative to reduce the destructive effects of water at high speed. Work on energy dissipation are critical elements in the construction of hydraulic structures, these have been developed based on the experience and wealth of knowledge in the field, however, the design of these structures involves laboratory studies, collection prototype field data, statistics, among others. In order to assist in this effort to collect information useful in the design of structures of energy dissipation information current work is presented with information obtained from laboratory data relevant parameters of structures including willing obstacles especially to achieve this objective. The main objective of the study is to have design elements to build a structure of energy dissipation decreases the undesirable effects present in the spillways flow with a sufficiently quieted to avoid structural damage. This was done with the support of a laboratory physical model provided for this purpose. For testing of the physical model ? angle was set in one position and the following dimensionless parameters were varied: Lh/Lv, d/D, where D is the maximum diameter of the tests performed. Also the velocity profiles of all testswere measured at 0.12mfrom the point of supply to the water structure in the physical scale model. There are evidences that the variable that dominates the energy dissipation in these structures is the change in diameter of the cylindrical obstructions. © 2015 Taylor & Francis Group, London.
