Note (General): An iterative calculation method was applied to identify two different instability modes in a three-dimensional boundary layer near attachment-line on a yawed cylinder. The point disturbance originating from a small hole on the cylinder was dispersed in the wedge-shaped region which consists of two types of unstable waves. Detailed hot-wire measurements illustrated the wave crests suggesting the each distribution of phase line for the two instability modes. The iterative calculation based on an assumption for the distribution function of the amplitude successfully provided the decomposition of the original experimental data into the two modes. The decomposition enabled us the comparison with the prediction by Itoh's linear stability theory and the identification of these modes, the streamline-curvature (S-C) modes and cross-flow (C-F) modes.
