Abstract
Turbulence is the phenomenon of difficult to understand and can be described as fluctuations in the field of flow in space and time. The process of forming and developing a turbulence is complex, since it is three-dimensional, transient and has several scales. In addition, it can cause significant effects on flow characteristics. When the forces of inertia of the fluid become significant, if compared with the viscous forces, it occurs to the turbulence and it presents in a high number of Reynolds. In this work, the RANS-based turbulence models used in OpenFOAM (Open Field Operation and Manipulation) were tested in unstructured hybrid meshes and their results compared to Arya and Shipman (1981) experimental data performed in a triangular 2D elevation. The results showed, even if simulated in a two-dimensional condition, good agreement with the experimental ones and a good computational performance, compared with the results obtained by Valle et al. (2010), who worked with Ansys CFX.
