Abstract
In order to analyze and understand the flow behavior in hydraulic structures, scale models are built; however, in the case of the vortex-type energy dissipator, the helical nature of the flow makes its analysis and data measurement difficult; therefore, a full-scale numerical model was built to allow a more efficient analysis of the flow in this type of dissipator. The computational fluid dynamics methodology was applied using the appropriate software. First, the heatsink geometry was created, then the meshing, after the boundary conditions and physical parameters were established, with which the model was solved, obtaining results that were validated with experimental data of the physical model, to finally analyze the prototype. The results obtained not only demonstrated the applicability of Computational Fluid Dynamics (CFD) in the hydraulic design and its calibration, but also provided a spatial distribution of the hydraulic characteristics along the prototype, an essential aspect in the design of this type of structures.
