WebNov 2, 2024 · Transonic buffet is a flow instability caused by an interaction between a shock wave and a shock induced separation. This phenomenon induces a large amplitude oscillation of the shock wave position and of the size of the flow separation, inducing variation of the integrated forces on a wing. WebOct 14, 2024 · When shockwave-induced flow separation happens, a flow instability may appear which is called shock buffet. This involves an oscillatory move of the shock (back and forward) accompanied with an oscillation of pressure forces on the wing which will cause vibrations to the whole body of the aircraft.
