Abstract
Experiments have been performed on a laminar flat-plate boundary layer undergoing transition to turbulence. Reproducible disturbances were introduced via a loudspeaker embedded at some upstream location and their evolution over the plate measured using hot-wire anemometry. A new technique has been used to estimate the number of independent modes in phase portraits reconstructed from the experimental data. Nonlinear maps were then fitted that explicitly model the spatial evolution of disturbances. The properties of these maps have been investigated.
