Abstract
The flow around surface-mounted cube under neutral atmospheric boundary layer was simulated using two-equation turbulence models. The accuracy of two-equation turbulence models to model the flow fields were compared against full y documented experimental data. To build low computational cost, mesh refinements were investiga ted through mesh independence study by means of standard wall functions for the near wall treatment. All the two-equations turbulence models are shown to be underpredict the separation length and overpredict the reattachment length near the cube wall. In particular, the standard k-ε turbulent scheme shows good agreement with experimental data of streamwise velocity flow along the symmetry plane behind the cube.
