Abstract

The present research was made to improve the engineering perspective concerning the computational fluid dynamics method. The main purpose is to obtain the limits of different turbulence models and to establish which of them is the most suitable for different Reynolds number flows. The flow configuration was a typical one, named backward facing step, which is widely used to investigate flows experimentally and computationally. The study involves multiple stages, from creating the geometry and meshing the experimental model to simulating all the conditions to obtain sufficient data to compare the turbulence fluid flow models with experimental results.
