Understanding jet noise.

چکیده

Jets are one of the most fascinating topics in fluid mechanics. For aeronautics, turbulent jet-noise modelling is particularly challenging, not only because of the poor understanding of high Reynolds number turbulence, but also because of the extremely low acoustic efficiency of high-speed jets. Turbulent jet-noise models starting from the classical Lighthill acoustic analogy to state-of-the art models were considered. No attempt was made to present any complete overview of jet-noise theories. Instead, the aim was to emphasize the importance of sound generation and mean-flow propagation effects, as well as their interference, for the understanding and prediction of jet noise.

Session 1pNS: Noise 1pNS5. On near-field acoustical inverse measurements of partially coherent sources

The sources of jet noise have been investigated through the use of near-field array measurements. An understanding of spatial coherence properties in the jet near field leads to insight about source composition. A metric called coherence length is a useful tool for summarizing near-field coherence information. Near-field coherence lengths are presented in this work for a full-scale jet, which s...

Simulation and Modeling of Turbulent Jet Noise

Jet noise reduction remains an important long-range goal in commercial and military aviation. Comparedwith their early counterparts, modern, ultrahigh-bypass-ratio turbofans on commercial aircraft are very quiet, but evermore stringent noise regulations dictate further reductions. In addition, hearing loss bypersonnel and community noise issues are prompting the military to seek noise reduction...

Preliminary Investigation of Multilobe Fighter Jet Noise Sources Using Acoustical Holography

An understanding of jet noise source mechanisms can facilitate targeted noise reduction efforts. This understanding has been enhanced with acoustic imaging technologies, such as near-field acoustical holography (NAH). In this study, multisource statistically optimized NAH (M-SONAH) was used to image the sound field near a tethered F-35 aircraft at multiple frequencies. A linear microphone array...
