The transitional process in a boundary layer is determined by a mechanism of generation and interaction of various instabilities. Small oscillations may cause primary instability – two-dimensional waves, the Tollmien–Schlichting (TS) waves. The growth of such TS waves leads to a streamwise periodic modulation of the basic flow, which gets sensitive to three-dimensional, spanwise periodic disturbances. In order to study the behavior of instabilities, quantitative data of velocity fields with known initial conditions have been acquired in a flat plate boundary layer, in the TUG wind tunnel using Stereo PIV.
