The Generation and Radiation of Supersonic Jet Noise. Volume II. Studies of Jet Noise,Turbulence Structure and Laser Velocimetry.

摘要

This volume discusses (1) turbulent mixing noise tests and observations relative to effects of temperature and Mach number on intensity,directivity,and spectra; (2) numerical solutions of the Lilley theory for sound radiated from point sources simulating small-scale turbulence noise sources,and comparisons of these solutions with experimental data relating to temperature and velocity effects on directivity and spectra; (3) the theory describing the development of the large-scale coherent motion of the jet structure and the far-field noise radiated from this turbulence; (4) a detailed discussion and interpretation of the jet turbulence and mean velocity data;and (5) a comprehensive description of the shock-associated noise tests, a preliminary description of the broadband shock-associated noise model,and a discussion of shock-associated noise in the overall jet noise picture.
