AbstractThis paper presents a methodology to estimate the wind tunnel wall interference with RANS simulations. The method involves a pairing process between confined and aerodynamically equivalent free air simulations that is carried out through automatic optimisation. Wall corrections are derived for a major industrial wind tunnel (ONERA S2MA wind tunnel located in Modane). The tunnel is a transonic pressurised tunnel with perforated walls that can be sealed to achieve a guided test section. In order to model the porous walls in the RANS simulations, the characteristics of the walls were measured with a specific experiment.On the whole, in the linear aerodynamic domain, the RANS corrections are similar to the current correction strategy but require a higher CPU cost. The benefit appears in non-linear regimes (high lift or high Mach number).
