Abstract
The nonlocalized receptivity of Falkner-Skan boundary layers is analyzed. An acoustic disturbance in the free stream interacts with a surface-generated disturbance to excite the natural boundary-layer instabilities. Results for the streamwise evolution of disturbances are presented along with receptivity amplitudes. The results show that favorable pressure gradients give rise to slightly larger receptivity amplitudes, over a narrower band of surface wave numbers. Conversely, adverse pressure gradients produce slightly smaller receptivity amplitudes, over a broader band of surface wave numbers.
