1. Response of shear flows to external disturbances Contents: 1. Acoustic receptivity of laminar separating boundary layer 2. Acoustic receptivity of laminar micro jet Multimedia files – 7/13

2. The following examples are visual demonstration of strong effects on the flow pattern which can have external perturbations coupled with the shear-layer instabilities
