Wave Processes in Transonic Airfoil Flows
Upstream moving pressure waves are observed in transonic flows over airfoils already for decades. They can be generated actively by flap or airfoil oscillations . But, they are also naturally present in airfoil flows [1, 4]. Upstream moving pressure waves can lead to flow instabilities by forcing shock and stagnation point oscillations. Furthermore, it is expected that they affect the laminar-turbulent transition . Hence, the phenomenon is of great engineering interest.
