Modelagem hidrodinâmica tridimensional em canais utilizando o modelo de turbulência k-e

Abstract

Turbulence is the most complex phenomenon of fluid movement. Several models have been tested for the turbulence in channels. The computational model used is the k- model threedimensional isotropic. This model was developed for total turmoil, with the advantages of simple operation and low computational cost, so it is widely used. Was implemented in three-dimensional modeling of the hydrodynamic flow in the channel. The simulations compare models with experimental data, noting their suitability. The k- hydrodynamic model proved to be suitable for simulations on channels. The SIMPLE algorithm showed an excellent performance. The sample tested showed a good fit between the k- model, the turbulent viscosity model and experimental data.
