The implementation of advanced low-emission aircraft engine technologies and the
reduction of noise from airframe, fan, and jet exhaust have made noise contributions from an …

This article proposes a review of the state of knowledge in the field of combustion noise. The
survey comprises an initial discussion of indirect and direct noise sources and their general …

Combustion noise is becoming increasingly important as a major noise source in
aeroengines and ground based gas turbines. This is partially because advances in design …

Multiscale physics is the interaction of different physical processes occurring at largely
separated scales. In combustion, many elementary reactions combine to only a few, but still …

A hybrid computational fluid dynamics (CFD)/computational aero-acoustics (CAA) approach,
in which large-eddy simulation (LES) and APE-RF (solution of the acoustic perturbation …

Combustion generated noise of a turbulent spray flame has been investigated using a
hybrid Computational Fluid Dynamics/Computational Aero-Acoustics (CFD/CAA) framework …

The sound emission from open turbulent flames is dictated by the two-point spatial
correlation of the rate of change of the fluctuating heat release rate. This correlation in …

A model for the prediction of combustion-generated noise in non-premixed flames has been
developed. This model is based on Lighthill's acoustic analogy and employs the …

The combustion noise produced by a confined, turbulent, premixed swirl burner is predicted
with large-eddy simulation of compressible, reacting flow. Characteristics-based state-space …

This paper presents a numerical study of the sound generated by turbulent, premixed
flames. Direct numerical simulations (DNS) of two round jet flames with equivalence ratios of …
