Abstract
Surface irregularities and vibration, free-stream turbulence and other factors lead to the penetration of three-dimensional perturbations into the boundary layer. Classical research on the transitional boundary layer has been restricted to a low degree of turbulence and the introduction of a plane perturbation wave. The present study concentrates on the development of three-dimensional perturbations created in a model experiment, both mechanically and by means of plane elastic plates, for various Reynolds numbers. The results are analyzed on the basis of the measured spectral and correlation characteristics.
