A strategy for predicting high-lift aerodynamic flows is presented that employs laminar–turbulent transition modeling, based on amplification factor transport, coupled with a hybrid Reynolds-averaged Navier–Stokes (RANS) and large-eddy simulation (LES) methodology. This modeling has been implemented in an overset, structured, finite difference computational fluid dynamics solver, and the predictive capabilities are demonstrated for the widely studied three-element MD 30 P / 30 N high-lift airfoil. Lift forces, surface pressure distributions, and velocity profiles are compared for fully turbulent and transitional hybrid RANS/LES simulations. The inclusion of transition prediction has a net favorable effect when compared to an experimental reference; however, some discrepancies between measurement and prediction are not fully reconciled.
