The correlation between wind tunnel experimental results and free stream flight results is difficult even for incompressible flows and 2D configurations. This correlation becomes more difficult to be found if the geometrical configuration contains high lift devices such as Kruger and flaps due to the significant amount of separations. Furthermore, the walls of subsonic wind tunnel cause massive wave pressure reflections especially for high blockage, which affect dramatically the aerodynamic coefficients for experimented models . Unfortunately, very few papers and books deal with this delicate subject even if the appearance of subsonic wind tunnel dates over 100 years ago. For this reason, the present paper deals with this complex subject in order to bring some new light in this complex field. This paper is based on an impressive number of RANS simulations for plain airfoils and 2D high lift configurations for wind tunnel and free stream conditions in order to find some useful correlations for INCAS subsonic wind tunnel.
