The Generation, Radiation and Prediction of Supersonic Jet Noise. Volume 1

Abstract

The work presented in this report forms a continuation of the fundamental studies on the generation and radiation of supersonic jet noise, reported in technical reports AFAPL-TR-72-53 (six volumes), AFAPL-TR-74-24, and AFAPL-TR-76-65 (four volumes). The total noise from a supersonic jet is taken to consist of contributions from three independent noise sources: (1) small-scale turbulent mixing noise, (2) noise from large-scale turbulence structure, and (3) shock-associated noise. The generation, radiation and prediction of each of these noise components is described in this report. In addition, the mean and turbulent flow characteristics of heated and unheated, subsonic and supersonic jets, measured by a laser velocimeter system, are also presented. Finally, a computer program for the prediction of jet noise, based on fundamental principles as far as possible at the present time, is presented and described in the form of a user's guide. A complete listing of this computer program is given in the Appendix volume (Volume 11) of this report.
