Note (General): In order to investigate the mechanism of wall turbulence generation, we have been studying a subcritical transition in a flat-plate boundary layer experimentally, through observing its nonlinear response to energetic hairpin eddies acoustically excited near the leading edge of boundary-layer plate. In this paper, our recent results on the development of wall turbulence structure in this transition is presented to reveal that the break-up of three-dimensional wall shear layers (with streamwise vortices) into hairpin eddies leads to wall turbulence. The effect of riblets on the development of wall turbulence is also reported and discussed.
