Hydrodynamic - acoustic filtering of a supersonic-underexpanded jet
Résumé
The main noise that is perceived inside the cabin of an airplane originates in the turbofan engines and their associated exhaust jets. Due to flight conditions, a pressure difference appears at the exit of the secondary flow which engenders a series of expansion and compression waves known as shock-cells.
