Experimental aeroacoustics study on jet noise reduction using tangential air injection [PDF]
, 2011 PhDAircraft jet exhausts are a source of undesirable noise and continue to be an area of investigation driven by increasingly stringent regulation. The noise is produced by the unsteady mixing of the jet with the surrounding air and is dominated by the ...

Active Jet Noise Control of Turbofan Engine Based on Explicit Model Predictive Control
Applied Sciences, 2022 The active jet noise control received significant attention due to the little influence it has on the engine performance. The active jet noise control is a multivariable problem because it needs to achieve the simultaneous closed-loop control of jet ...

A Numerical Simulation of the Underwater Supersonic Gas Jet Evolution and Its Induced Noise
Applied Sciences, 2023 To explore the complex flow field and noise characteristics of underwater high-speed gas jets, the mixture multiphase model, large eddy simulation method, and Ffowcs Williams–Hawking (FW–H) acoustic model were used for simulations, and the numerical ...

Sound power and acoustic efficiency of an installed GE F404 jet engine [PDF]
JASA Express Letters, 2023 Classical jet noise theory indicates that radiated sound power is proportional to the jet velocity raised to the eighth and third powers for subsonic and supersonic jets, respectively.
