ΠερίληψηThe academic computational fluid dynamics code Galatea-I is used in this study for the prediction of the flow over the DLR-F11 high-lift configuration, presented in the Second AIAA High-Lift Prediction Workshop. The proposed solver employs the Reynolds-averaged Navier–Stokes equations, modified appropriately by the artificial compressibility method and combined with the shear-stress transport turbulence model to account for the simulation of incompressible turbulent flows. Attention is mainly directed toward the assessment of the alternative, artificial compressibility methodology against such test cases because the majority of the workshop participants had implemented compressible Reynolds-averaged Navier–Stokes codes with preconditioning matrices instead. To this end, the flow at various angles of attack over the DLR-F11 aircraft model is studied, whereas the obtained results are compared to the available experimental data as well as simulation results produced by reference solvers. A satisfactory agreement is reported, demonstrating the proposed methodology’s potential to accurately predict such complex flows and adapt to uncommon areas of use.en
