초록
A free stream vortical disturbance generated by a single axial vortex of periodically modulated strength was used to investigate vortical receptivity of a flat plate boundary layer to low-frequency spatially localized free-stream disturbances. It was found that the boundary-layer response was dominated by stream-wise velocity perturbation (streak). However, in contrast to the stationary streaks considered by Boiko (2002), its intensity showed no pronounced growth along the flat plate.
