Estudio numérico y comparativo del efecto de turbulencia en codos y dobleces para distribución de agua sanitaria

This article presents the numerical and comparative study of the effect of turbulence on elbows and bends for the parameters of an inch, by means of CFD and under the same working conditions (velocity, pressure and temperature), to determine the fluctuation in turbulence of kinetic energy between these two accessories varying the turbulence models. Two methodologies were used for this investigation, kappa-epsilon (k-ε) and kappa-omega (k-ω). The method (k-ε) is divided into three models: standard, RNG and realizable, in which turbulence of kinetic energy and of dissipation is transformed. The method (k-ω) also has three variants: standard, SST, BSL.
