Modelación numérica con OpenFOAM del flujo de los paneles sumergidos y comparación numérica – experimental

Abstract

Submerged panels are transverse structures in the river bed that have proven to be a simple, economical and reliable technical solution, in terms of the results obtained. They control the deposition of the sediment, for example, in the case of curves or meanders, to counteract the effect of centrifugal acceleration and thus avoid the erosion of the external bank and the deposits in the internal one. Channel stabilization occurs in terms of its alignment, generating a vortex that spirals downstream in the flow, whose helical secondary movement brings associated changes in the shear stresses in the bed that modify the topography of the bottom. Based on the doctoral thesis of Hamad Khaled (2015), Submerged Vanes Turbulence, Experimental Analysis, was modeled numerically with OpenFOAM free software, to obtain parameters such as velocities and pressures and compare them with the experimental results. Applied the RANS method and the turbulence sub model k - ω SST were obtained after several simulations and variations, results that without being exact correspond in terms of the same order of magnitude with the measured ones, with which it can be concluded the validity of the numerical simulation as an option to develop within the Hydraulics.
