The primary objective of this investigation is to determine experimentally the sources of jet
mixing noise. In the present study, four different approaches are used. It is reasonable to …

This is a review of the two-source model of jet noise. The model was developed
phenomenologically a number of years ago. One of the principal results associated with this …

This paper reviews jet noise research conducted at the National Aeronautics and Space
Administration (NASA) from the early 1950s to the present day. Research conducted by …

A novel application of the adaptive Fourier–Hankel (AFH) Abel algorithm to reconstruct the
radial density distribution of axisymmetric jets is presented. The fluid is imaged using the …

One of the principal challenges in the prediction and design of low-noise nozzles is
accounting for the near-nozzle turbulent mixing layers at the high Reynolds numbers of …

A coaxial jet originating from parallel coplanar pipe nozzles is computed by a compressible
large eddy simulation (LES) using low-dissipation and low-dispersion schemes in order to …

The noise emitted by an overexpanded round jet at a Mach number of 3.3 and a Reynolds
number of 105, computed in a previous study using large-eddy simulation (LES), is …

Temperature effects on the convection speed of large-scale structures in supersonic
temporally developing jets and on the steepened aspect of the acoustic waves generated by …

A possible fundamental physical mechanism by which instability modes generate sound
waves in subsonic jets is presented in the present paper. It involves a wavepacket of a pair …

Two temporally developing isothermal round jets at a Mach number of 0.9 and Reynolds
numbers of 3125 and 12 500 are simulated in order to investigate noise generation in high …
