摘要：
The unsteady boundary layer transition over an airfoil is investigated experimentally for several Strouhal numbers. Continuous wavelet analysis is used to highlight the key mechanism of unsteady boundary layer transition. A quasi-steady approach is used to compute wave amplifications which are compared successfully with experimental amplifications.
