This paper describes a prediction of the laminar-turbulent transition on a swept wing using linear PSE (Parabolized Stability Equations). The linear PSE includes the effects of nonparallel mean flow, body curvature and streamline curvature which have been ignored in the classical analysis based on Orr-Sommerfeld equation. The result shows that the wall curvature has significant effect on the growth rate of the unstable disturbances. The comparison with experimental shows fairly good agreement in the wavelength of the most unstable mode.
