The Impact of Acoustic Synthetic Jet Actuator Parameters on the Generated Noise [PDF]
Synthetic jet actuators are becoming increasingly popular for enhancing electronic heat transfer. However, their use is currently limited due to the high noise they generate. This article examines how actuator parameters (orifice diameter, orifice length

Localization of Noise Sources in Jets Flowing from Lobed Nozzles [PDF]
The noise of jets formed using conical and lobed nozzles has been measured. The possibility of jet noise reduction by using a lobed nozzle shape has been demonstrated.

Active Jet Noise Control of Turbofan Engine Based on Explicit Model Predictive Control
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
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]
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.
