Extreme effect of noise pollution includes deafness and mental breakdown and in main
cities automobiles are a main source of noise. The literature concentrates on the side mirror …

The bevelled nozzle is a promising noise control approach and has been tested to suppress
the noise levels in supersonic circular jets, but not in rectangular jets so far. In this study …

In this paper, we seek to understand the influence of TPS standard nozzle shape on jet
noise and improve the accuracy of flow and pressure ratio of aeronautical simulation …

An experimental study is conducted to determine the effect of chevrons with zero penetration
angles at the CD nozzle exit on an emitted noise field. The implication of passive control is to …

In this study, the parameters of a wave-packet model for subsonic jet noise prediction are
systematically optimized by leveraging near-and far-field data obtained from the large-eddy …

This paper reports a parametric investigation of the effect of the nozzle exhaust initial
conditions on the wavelet separated acoustic pressure generated by a single stream …

Supersonic impinging jets may cause many adverse ground effects, including surface
erosion, nonuniform surface heat transfer, lift loss, and acoustic loading. In this study …

Noise pollution from aircraft is a critical environmental issue, affecting not only wildlife but
also human health and comfort, especially for populations living near airports. The recent …

This study introduces a series of processes aimed at understanding the noise characteristics
generated by jet engines and devising measures to mitigate them through interdisciplinary …

Energy efficiency, exergy efficiency & destruction, economic, environmental, and error
analysis analyses have been presented for the proposed trigeneration system. The metrics …
