In this study, local skin friction was measured on the suction surface of the airfoil by using the oil film interferometry (OFI). The airfoil model had NACA0012 wing section and the airfoil flow condition was under the lifting condition of Re=8.0×104. OFI was performed with adjustment of angle of light source and camera for local airfoil surface. It was found that the adjustment affected measurement accuracy of local skin friction. The measured local skin friction had difference of less than 2% compared to the LES results by Miyazawa et al.1).
