RESUMO

The presented paper concerns the application and validation of Large Eddy Simulation (LES) for the prediction of the flow around a prolate spheroid at different angles of attack. The objective is to evaluate the applicability of LES for practically relevant high Re-number flows, to study the influence of subgrid modeling and grid resolution on the quality of the results and to discuss and compare the flow and turbulence dynamics. The LES' use different subgrid and wall-models and are performed on different grids in appropriate combinations. Simulations are performed at α=10° and 20° angle of attack, and comparison with experimental data is carried out for both pressure and velocity. Reasonable agreement is found for both angles of attack, and the influences of resolution and subgrid model are both comparatively small.
