摘要：
Within the scope of technical application it is necessary to simulate flows with separation not only at "academic" Reynolds numbers by direct numerical simulation (DNS), but also at higher Reynolds numbers by means of large eddy simulation (LES) or very large eddy simulation (VLES). The flow around a sphere at Re=50 000 has been calculated on unstructured grids with the Smagorinsky subgrid model and data is compared with available measurements. It is necessary to evaluate existing models and test them on simple geometries for the future application on real problems. Results indicate that the agreement between simulation and experiment is within the range of the experimental error.
