Abstract
This report presents results for 3d CFD computations for a transport aircraft with a forward swept wing. RANS computations are performed for fully turbulent (SST k-ω model) and transitional (en method) boundary layer flows. Special focus is set on grid requirements for transitional computations and the convergence behavior of the predicted transition position. The results are used in the DLM correction method CREAM to show the influence of a free boundary layer transition on the unsteady aerodynamics. The report presents the results for the milestone “M 1.1.3: Num. Simulationen am 3D-Flügel ausgewertet” in work package HAP 1 of the project ALLEGRA.
