Resumo
Computational 2D and 3D studies of the wind behavior flowing over hypothetical, symmetrical hills have been performed. The numerical simulations are computed using a CFD software, which uses the Finite Volume Method to solve the conservation equations. The present work is divided in two cases: one two-dimensional, steady-state case in which the surface roughness is neglected, and one three-dimensional, in which subcases the use of surface roughness and the steady and transient regimes is alternated. The problem is solved with the same turbulence models, but both the steady and transient regimes are used. Also the surface roughness is considered in one of the cases. Throughout the study, both the k-ε e k-ω SST turbulence models were used. Results are presented so that comparisons between 2D and 3D simulations are favored. Those, in turn, are compared with experimental data provided by wind tunnel experiments.
