Organized structures in turbulent jets can be modeled as wavepackets. These are
characterized by spatial amplification and decay, both of which are related to stability …

Guided-jet waves have been shown to close resonance loops in a myriad of problems such
as screech and impingement tones in jets. These discrete, upstream-travelling waves have …

scale resolving simulations for jet noise prediction of configurations of increasing complexity …

The possibility of jet-installation noise reduction has been experimentally demonstrated
using a flat-plate fitted with flow permeable metal foam fitted at the trailing-edge. Tests were …

Installed jet noise is studied by means of a simplified configuration comprising a flat plate in
the vicinity of a round jet. The effects of Mach number, jet-plate radial distance, and trailing …

We present a numerical method to compute the acoustic field scattered by finite perforated
elastic plates. A boundary element method is developed to solve the Helmholtz equation …

The turbulent mixing noise radiated by a Mach 0.9 jet is investigated. The focus is put on the
proper calculation of acoustic propagation effects by means of adjoint Green's function that …

A model for sound generation by a jet in the vicinity of a flat plate, mimicking an exhaust jet
installed near an aircraft wing, is presented. An earlier model (Cavalieri et al. J. Sound Vib …

The noise radiated by an isothermal, single-stream jet with a Mach number M= 0.9 and
diameter-based Reynolds number ReD= 106 is investigated numerically without and with …

The link between jet-installation noise and the near-field flow features of the corresponding
isolated jet is studied by means of lattice-Boltzmann numerical simulations. The …
