Summary
A theoretical study is made of the excitation of Tollmien — Schlichting waves by a mechanical vibrator or thermal source that heats a small part of a surface in subsonic stream. According to results of most practical concern, it is possible to reduce essentially the amplitude of forced oscillations and even to attain their full attenuation by changing the form of a membrane. The similar effect is reached when the temperature of the heated part varies. Hence a possibility arises to damp travelling Tollmien — Schlichting waves using different devices of both mechanical and thermal nature.
