In computational predictions of 3D full-size high-lift devices at take-off and landing the accuracy is critical. The accuracy in the modelling of turbulence and transition will be addressed in this study. Transition will be predicted by computing the growth rate of disturbances using database methods, local and non-local stability analysis. Turbulence will be modelled using improved and optimised EARSMs where streamline curvature effects are fully accounted for and the baseline two-equation models are optimised. A coupling procedure between transition prediction and RANS will be developed. The improvements will be demonstrated on 3D high-lift configurations using industrial hybrid CFD codes.
