Modelación numérica del flujo en un descargador a vórtice aplicando mecánica de fluidos computacional (CFD)

Abstract

This present work aims to the numerical modeling of the drop vortex structure "El Colegio" using a specialized software Computational Fluid Dynamics, called Flow 3D. This software allows to solution Navier-Stokes equations for each cell defined in a domain meshing hydraulic structure. To run the numerical model provides input data, as the hydraulic structure geometry, flow rates, absolute roughness, turbulence model to the software. It’s a numerical model with some variables as input data, of which there is no absolute certainty, is required to compare and validate the results of numerical modeling with other results, to the effect the results of physical modeling were used drop vortex "El Colegio" by the CIERHI in 2002. Depending on the comparison of results between numerical model and physical model input variables affecting the results, and then to obtain new results and to validate numerical model are calibrated. In addition to the validated numerical model behavior helical flow standpipe it was simulated for different lengths of which was obtained as a result theoretical the corroboration of parameters such as the efficiency of energy dissipation standpipe or output speeds.
