This paper describes a method to measure skin friction distributions on wind tunnel test model. Skin friction is one of the major sources of airplane drag. Two optical measurement methods are described in this paper. One method measures the thickness and tracks the movement of luminescent oil flowing along the test model surface, which shows qualitative skin friction distribution on the model. Another method measures quantitatively local skin friction. The two optical measurement methods are combined then quantitative skin friction distribution is measured. To demonstrate its validity, the method has been applied to an incompressible flow around a vortex generator on a flat plate. As a result, the method measured successfully quantitative skin friction distribution of the flow around the vortex generator.
