| Popis: |
Results from numerical simulations of turbulent flow around a surface-mounted cube and over a surface-mounted square rib are presented. The first problem is treated by solving the Reynolds equations together with the standard k − ϵ turbulence model, for 0° and 45° orientation of the flow obstacle, in uniform and boundary layer incident flow. The second problem is solved by applying the concept of large-eddy simulation. In both calculation concepts, sufficient spatial resolution is essential to get satisfying agreement with experimental data in the critical flow regimes, e.g. above the top face of the flow obstacles. The computations based on large-eddy simulation are very expensive but can provide excellent agreement of the numerical results with the experimental data for the second-order statistics. |
