| Sumario: | [EN] Free falling jet is one of the most common energy dissipation methods used in the overtopping of dams. This work presents the time and frequency analysis of pressure measurements obtained at the bottom of a plunge pool downstream of free falling jets in an experimental facility. A relative large device (falling height up to 2.85 m and impingement jet velocities between 5.3 and 7.6 m/s) has been used in the study. The behavior of the four types of free falling jets classified in previous studies has been analyzed in the time and the frequency domains. The study focuses on the pressure on the stagnation point. The pressure distributions near the stagnation point have been also analyzed. Finally, the results have been compared with the frequencies behavior for circular and rectangular jets available in the literature. |
