Análisis Numérico Bidimensional Aguas Abajo de Paneles Sumergidos Aplicando el Modelo IBER

Abstract

This work consists in the comparison of the physical model, with the results obtained through the IBER bidimensional software, downstream of submerged panels. The physical modeling was carried out in the Morphodynamics laboratory of the Department of Hydraulic, Maritime and Environmental Engineering, Ports of Barcelona, in Barcelona Tech. UPC University. In physical modeling, sensors were placed that took data over time and were distributed in such a way that measurements were made in the x, y, and z directions. A data treatment was carried out to obtain average speeds from the three dimensions, that is to say, the speed in depth was averaged and thus the calibration of the numerical model could be performed. Results were obtained for half speed, turbulence, using the K-ε model and it was checked if there is a start at the movement threshold. The comparison of the results obtained in the modeling allowed a qualitative and quantitative analysis of them. This demonstrates that the IBER software is a tool that can optimize the design of submerged panels, in the case of determining speeds, k turbulent kinetic energy and sediment movement threshold, while, for energy of turbulent dissipation, this result is not to closer.
