We present an explicit finite difference time domain method to solve the lossless Westervelt
equation for a moving wave emitting boundary in one dimension and in spherical symmetry …

This study deals with a class of variable coefficients second-order parabolic moving
boundary problems. The evolution of the domain is considered to be an unknown function …

We present a physical model and a numerical method based on a space-and time-
dependent Galilean-type coordinate transformation to simulate acoustic waves in the …

We investigate the amplitude modulation of acoustic waves in accelerating flows, a problem
that is still not fully understood, but essential to many technical applications, ranging from …

A numerical method is presented to solve the propagation of sound waves in a two-
dimensional domain in the presence of rotating obstacles without flow. It relies on a domain …

A finite element method in the frequency domain is proposed for solving scattering problems
with moving or, more generally, deforming boundaries. First, the original problem is rewritten …

Résumé Cette thèse a pour objectif de proposer une méthode permettant de simuler le bruit
d'origine aérodynamique d'un ventilateur axial. Au vu de la faible vitesse de l'écoulement …

A finite element method in the spectral domain is proposed for solving wave scattering
problems with moving boundaries or, more generally, deforming domains. First, the original …
