Journal ArticleDOI
Theoretical model for sound radiation from annular jet pipes: far- and near-field solutions
Gwenael Gabard,R.J. Astley +1 more
TL;DR: In this article, an analytical model for sound radiation from a semi-infinite unflanged annular duct is presented, where noise propagates along the annular bypass duct, refracts through the external bypass stream and radiates to the far field.
Journal ArticleDOI
Discontinuous Galerkin methods with plane waves for time-harmonic problems
TL;DR: The main feature of the method is the use of plane waves instead of polynomials to approximate the solution in each element, which requires only a small number of elements per wavelength to obtain accurate solutions and is more efficient than high-order DRP schemes.
Journal ArticleDOI
A comparison of impedance boundary conditions for flow acoustics
TL;DR: In this paper, a comparison of the Myers condition and the boundary layer profile of turbofan engines is presented, and it is shown that boundary layer thickness has a significant impact on sound absorption, although its actual influence depends on the details of the incident sound field.
Journal ArticleDOI
A computational mode-matching approach for sound propagation in three-dimensional ducts with flow
Gwenael Gabard,R.J. Astley +1 more
TL;DR: In this paper, a finite element (FE) mode-matching approach for duct acoustics with flow and circumferentially varying liners is presented for sound attenuation in turbofan inlets and bypass ducts.
Journal ArticleDOI
Efficient implementation of high-order finite elements for Helmholtz problems
TL;DR: An efficient implementation of the high‐order finite element method (FEM) for tackling large‐scale engineering problems arising in acoustics with the ability to select automatically the order of interpolation in each element so as to obtain a target accuracy while minimizing the cost.
