This article presents experimental and numerical studies on the effect of the Reynolds number on transition location for a simplified multi-element wing. The main phases of the test preparation and the main results of the data analysis carried out within the EUROLIFT EC funded programme are given in the first part. In the second part of the article, recent assessments of the ONERA elsA CFD software where transition is computed during the Navier-Stokes calculation are presented for both the effect of change in incidence at a given Reynolds number and the change in Reynolds number at constant angle of attack. The upper slat region is the main concern of this article, as this element was better equipped and analysed after the experiments. Flap transition is also considered in the computations. For themain wing, turbulent flow is imposed in the computations, as leading-edge contamination occurred in the experiments.
