Jet Noise: A Survey and a Prediction for Subsonic Flows

Abstract

The state-of-the-art of the prediction of turbulent jet noise is surveyed. This survey includes a description of the available experimental data on subsonic and supersonic, cold and hot jets, and of present theoretical treatments of the mechanisms of turbulent jet noise production. A detailed analysis of the production of subsonic cold jet noise, based on the acoustic analogy formulation, is described, and results of computations using this analysis and a turbulent kinetic energy analysis of the jet flow field are presented and compared with representative experimental data.
