Numerical predictions of the NLF(1)-0416 airfoil operating at moderate Reynolds numbers and low angle of attack have been carried out by coupling Navier-Stokes and exp(N) transition prediction methods. The consequences of either prescribing point transition or applying a transitional flow model in the Navier-Stokes solver have been systematically investigated. Several classical models have been considered in this study.
