    Análisis numérico 3D de una rotura de presa utilizando el método VOF y el modelo de turbulencia LES
    (2018) Boix, Julia; Sánchez Cordero, Esteban Remigio; Gomez Valentin, Manuel; Bladé Castellet, Ernest
    In this paper, three-dimensional numerical analysis of dam-break flow pattern in a laboratory-scale is reported. The simulation was performed using the open source computational fluid dynamics (CFD) solver based on finite volume method (FVM) – OpenFOAM. Turbulence is treated using large eddy simulation (LES) approach. The free surface is tracked using the Volume of Fluid method (VOF). The numerical results are assessed against published experimental data. Water depth and pressure measures are used to validate the numerical model. The results demonstrate that the 3D numerical configuration satisfactorily reproduces the temporal variation of these variables with correct trends and high correlation with the experimental values

    Three-dimensional numerical analysis of a dam-break using OpenFOAM
    (Institute for System Programming of the RAS, 2017) Gomez Valentin, Manuel; Sánchez Cordero, Esteban Remigio; Bladé Castellet, Ernest
    This paper presents a 3D numerical analysis of flow field patterns in a dam break laboratory scale by applying the numerical code based on Finite Volume Method (FVM), OpenFOAM. In the numerical model the turbulence is treated with RANS methodology and the VOF (Volume of Fluid) method is used to capture the free surface of the water. The numerical results of the code are assessed against experimental data. Water depth and pressure measures are used to validate the numerical model. The results demonstrate that the 3D numerical code satisfactorily reproduce the temporal variation of these variables.
