dc.description.abstractProgress is made in the validation and use of a shareable, royalty-free, non-commercial Computational AeroAcoustics (CAA) post-processor for predicting the far-field noise radiated by acoustically active transonic flows. Building upon past validation tests of this Ffowcs Williams and Hawkings CAA post-processor, which is part of the Antares software suite, predictions are obtained of a single isothermal Mach 0.9 jet at a Reynolds number of approximately half million. A more challenging application to a dual-flux transonic isothermal jet issuing from two axisymmetric coaxial nozzles, with axially staggered nozzle exit planes, shows salient spectral roll-off rates and directivity patterns typical of this geometry, which represents an idealised turbofan engine exhaust configuration. This builds confidence in the application of this new tool to aeroacoustic research as well as to aircraft design.en
