Abstract

An unstructured-grid, Navier-Stokes flow solver is used to compute the transonic flow development over the SKF 1.1 supercritical aerofoil section, in clean configuration and equipped with either a trailing-edge flap or a leading-edge slat. A full differential Reynolds-stress turbulence model is employed, with wall-function near-wall boundary conditions, for the computations. Agreement between predicted surface pressure distributions and experimental data for the three high-lift configurations is satisfactory for the free-stream Mach number of 0.6 considered, over a range of incidence angles. There are some uncertainties in the wind-tunnel wall interference corrections to be applied to the experimental data, and there are also indications of possible leading-edge slat movement in the experiment under the large aerodynamic loads experienced in the cases considered.
