Characterization of Installation Effects for HBPR Engine, Part 4: Assessment of Jet Acoustics

This paper is the last part of a series of four papers characterizing the installation eects of a typical high bypass ratio engine jet using numerical simulations and particle image velocimetry. The global objectives are an improved understanding of the link between the jet ows and the generated noise, the validation of methods for computing the aerodynamic eld and the noise sources for industrial congurations, and the assessment of the benets
