This paper presents the results of validation exercise of a two-dimensional Navier-Stokes solver conducted for high-lift application by Bombardier Aerospace. The aim of the study was to investigate the capability of the code to accurately predict the complex flows around high-lift configurations and the requirements for successful computations. The experimental data for this validation comes from a dedicated two-dimensional high-lift test conducted in the Canadian Institute for Aerospace Research high-Reynolds number test facility. Three test cases have been selected from the experimental data: a clean airfoil, a slat-deployed configuration and a flap-deployed configuration. The parameters that were investigated included the extent of the computational domain, the wall spacing, local mesh refinement and turbulence modelling. Guidelines for the successful computation of airfoil high-lift flows are deduced from this study.
