Excitation of instability waves by sound —A physical interpretation

Attention is given to the excitation of the instability waves of a two- dimensional free shear layer by sound. The satisfaction of the wave number matching condition when there is a rapid amplitude variation of the incident sound waves is discussed. The broadening of the instability wave number spec...

Summary:Attention is given to the excitation of the instability waves of a two- dimensional free shear layer by sound. The satisfaction of the wave number matching condition when there is a rapid amplitude variation of the incident sound waves is discussed. The broadening of the instability wave number spectrum by mean flow variation may be sufficient to overlap with that of the incident sound wave. (O.C.)
