Optimización del cuenco disipador de energía excavado en el cauce receptor para colectores combinados aplicando modelación cfd en openfoam.

Abstract

The tools for the application of computational fluid dynamics (CFD) are increasingly common when looking for solutions in hydraulic engineering with numerical modeling since they reduce the amount of resources and time that the physical modeling of an engineering problem could take. However, initial data will always be necessary to calibrate and validate a numerical model.

In this research work, the analysis and optimization of a typical structure of an stilling basin located at the discharge of a combined collector is carried out. The analysis is carried out by numerical modeling using the open source software package OpenFOAM; specifically the interFoam solver which uses the fluid volume criteria (VOF) and the RANS methodology for solving mass, energy and moment conservation equations in multiphase flows. The k-omega SST turbulence model is used for its quality to represent the phenomenon that will take place in this type of structure (hydraulic jump).
