Note (General)
Characteristics of secondary instability which originates from a longitudinal vortex pair due to the unstable inflectional velocity profile between their axes in a boundary layer is investigated experimentally. The longitudinal vortex pair is generated artificially by blowing air from a longitudinal slit in a flatplate. Behavior of secondary instability fluctuation under the influence of sound is also examined. A nonlinear interaction observed between generated sound frequencies and its corresponding peak frequencies is shown on spectrum analysis. The flow field under the influence of secondary instability is influenced by the sound.
