TL;DR: In this paper, a new scalable high-resolution CABARET MILES method coupled with a porous Ffowcs Williams-Hawking formulation for far-field noise modelling is applied for the computation of flow and noise from a high-speed turbulent jet, which corresponds to a converging axi-symmetric nozzle and static isothermal conditions of the Jet Exhaust Aerodynamics and Noise experiment.

TL;DR: In this paper, a generalization of this method allowing the decomposition of the jet acoustic field into azimuthal modes by means of reduced number of microphones is developed, and it is shown that jet noise measurements by only three microphones in each cross-section allow reconstruction of three different modes (axisymmetric, first, and second) for both low and moderate frequency bands.

Generalization of the method of azimuthal decomposition of an acoustic field of a compact source for measurements in the vicinity of a rigid surface
TL;DR: In this article, a method for decomposing the acoustic field of a compact source into azimuthal components using irregularly arranged microphones is proposed, which decomposes the source's acoustic field into two components.
