Abstract:

Contents Jets and Noise The development of engineering practices in jet, compressor, and boundary layer noise Scales pertinent to noise generation from a jet Estimation of the intensity of noise radiated from a subsonic circular jet General method for calculating the sound pressure field emitted by stationary or moving jets Jet noise at very low and very high speed An investigation of the near noise fields of a choked axi-symmetric air jet Noise from underexpanded axisymmetric jet flows using radial jet flow impingement The response of a simple panel to the pseudo-sound field of a jet Atmospheric absorption of noise Attenuation of sound in soft-walled circular ducts Flow perturbations generated by a shock wave interacting with a entropy wave Trends in boundary layer noise research A review of the sound-generating mechanisms in aircraft-engine fans and compressors Discrete noise generation and propagation by a fan engine A theoretical study of helicopter rotor noise A study of propeller noise research Review of sonic boom theory Recent results of sonic boom research Sonic bang simulation by explosives Second-order wave structure--planar flows and Lifting aerodynamic configurations with no sonic boom.
