It is necessary to correct data of supercritical airfoil for sidewall boundary-layer effects in transonic wind tunnel, thus investigating the aerodynamic characteristics of supercritical airfoil perfectly. In this paper, NASA SC (2)-0714 airfoil was numerically simulated with chosen grids, and compared with corrected EFD results. The Barnwell-Sewell(B-S) method was applied to correct sidewall boundary-layer effects of supercritical airfoil CH in NF-6 wind tunnel. It is shown that there was large disparity between CFD and uncorrected EFD results, while CFD and EFD results compared well after correction. The B-S method for sidewall boundary-layer effects correction of NF-6 wind tunnel is validated.
