Análisis del comportamiento del flujo a través de un vertedero en abanico y su subsecuente cuenco disipador mediante un modelo matemático de flujo en tres dimensiones

Abstract

In order to establish the flow pattern in the some facilities of the PACALORI Project, and to validate the results obtained through the small-scale physical model executed by the Water Management and Soil Research Program (PROMAS) and the Hydraulics and Fluid Dynamics Laboratory at University of Cuenca, through this study, the three-dimensional numerical modeling software FLOW-3D has been implemented to the facilities: Fan spillway and its subsequent sink basin. This software is based on the approximation of a control volume with a three-dimensional mesh for flow calculation by solving the Navier-Stokes equations using a turbulence model. Through this study will report results of numerical simulation that are compared and analyzed with qualitative and quantitative results obtained from the study of the small-scale physical model. Through the analysis and discussion of the results show the evaluation of the three-dimensional numerical modeling with FLOW-3D constitutes a complementary support to physical modeling to study the hydraulic performance in hydraulic structures and also to check the correct designs. Finally, recommendations are made to make way for the implementation of future studies to compare and analyze the performance of other models of numerical simulation as a tool for the design and analysis of the operation of hydraulic structures and flow processes in civil engineering projects.
