The spatial development of boundary-layer instabilities has been investigated experimentally in a flow régime where nonlinearities are important. Detailed measurements of the evolution of a regular periodic wavetrain into an irregular or chaotic one are reported. It was found that the broadband noise content of the motion grew very rapidly downstream when the amplitude of the periodic component was sufficiently large. The almost explosive growth of the broadband element provided velocity fluctuations with chaotic time series similar to those generated by mathematical models based on low-order differential equations.
