Abstract
An experimental study on the boundary layer instability was carried out in flat-plate boundary layers by means of controllable heat pulsing, introduced into the critical layer. The experimental results indicate that the two-dimensional linear theory which predicts the stability boundaries can be applied successfully in the initial period of disturbance amplification even in the presence of considerable three-dimensional components of disturbances. Compared to the “Klebanoff” (K-type) transition mechanism, the subharmonic routes started from lower fluctuation levels of initial disturbances or from lower Reynolds numbers. The maximum amplification of the disturbances occurred at particular oblique-wave angles, which agreed well with the prediction of Craik’s mechanism of a resonant triad. The potential and limitation of the heat-pulsing technique are also discussed in this paper.
