Concurrent finite element simulation of quadrupolar and dipolar flow noise in low Mach number aeroacoustics
(Elsevier, 2016-07)
Article
Accés obertThe computation of flow-induced noise at low Mach numbers usually relies on a two-step hybrid methodolgy. In the first step, an incompressible fluid dynamics simulation (CFD) is performed and an acoustic source term is ... -
Finite element computation of diphthong sounds using tuned two-dimensional vocal tracts
(European Acoustics Association (EEA), 2014)
Text en actes de congrés
Accés restringit per política de l'editorialFinite element methods (FEM) are increasingly being used to simulate the acoustics of the vocal tract. For vowel production, the irreducible wave equation for the acoustic pressure is typically solved. However, diphthong ... -
Residual-based stabilization of the finite element approximation to the acoustic perturbation equations for low Mach number aeroacoustics
(2016-12)
Article
Accés obertThe acoustic perturbation equations (APE) are suitable to predict aerodynamic noise in the presence of a non-uniform mean flow. As for any hybrid computational aeroacoustics approach, a first computational fluid dynamics ...
