Sound transmission through a finite-lined section in a rigid annular duct with swirling and sheared mean flow is analyzed with a new mode-matching method based on the conservation of the total enthalpy and the mass flow, which does not reduce to the

International audience; Noise pollution is a major concern for aircraft manufacturer during design and certification. Very high sound levels are recorded in take-off phases upstream of the engine fan, where multitonal noise components can appear (so-

A semi-empirical analytical model is developed that predicts the noise produced by a rotor ingesting a boundary layer in proximity to a hard-wall. The rotor boundary layer ingestion noise source is an important source to include when a rotor is insta

International audience; The present investigation targets the generation of airfoil trailing-edge broadband noise that arises from the interaction of turbulent boundary layer with the airfoil trailing edge. Large-eddy simulations, carried out using a

To account for vane camber effects in fan/outlet-guide-vane interaction noise prediction, a two stagger-angle method is proposed that extends a flat-plate cascade analytical model. This method is applied to fan tonal noise for which camber effects ar

An analytical solution to leading-edge noise produced by a translating two-dimensional flat plate ingesting turbulence in proximity to a hard-wall is presented. This is a relevant problem to calculate the installation noise of open rotors and un-duct

An advanced digital filter method is presented to generate divergence-free synthetic turbulence with homogeneous anisotropic velocity spectra. The resulting fluctuating velocity field is obtained through a superposition of anisotropic Gaussian eddies
