Resumen
Significant growth in the use of computacional tools is visible in this days, because it optmizes time and decreases costs, and also Works with the possibility of analisys of many factors, optimizing the results. Allying these concepts with the Hydraulic Engineering, this thesis presents a numerical comparative study of a hydraulic jump. It’s main use is energy dissipation, wich is usually applyed in the protection of hydraulic estructures. It promotes the absortion of the energy in the place of the impact, denominated stilling basins. Subsequently, an experience in an open channel was made, for the purpose of obtaining the values that is necessary for the calculation of the comparison parameters. The same experience was modelled and analysed in ANSYS CFX. In the simulation, the mesh was refined, in order to have more accurate results. Finally, the final results of velocity and pressure were analysed and compared. It was possible to observe that the simulation returns results that are very close to the ones that were experimentally calculated.
