SOME ASPECTS OF FREE SHEAR-LAYER INSTABILITY AND SOUND EMISSION

Abstract

The relative importance of instability fluctuations and turbulence as noise sources in a jet is discussed. Ways of detecting sound emission from instability waves in a jet are described. Some of the problems associated with supersonic disturbances in shear layers - from which the sound emission may be very intense - are also discussed. (Author)
