Abstract : This study compares the application of several variants of the $k - \varepsil- on$ model for the prediction of a stall around a two-body NLR airfoil. A Chen-Patel two-layer model and a Reichardt wall law ær combined or not with the Menter correction. The Reichardt wall-law does not give a good prediction of the stall, either with or without the Menter correction, although this second option is more accurate for non-detached flows. The stall is not predicted either by the original Chen-Patel two-layer model but well predicted if the Menter correction is added.
