Journal ArticleDOI
Stability and accuracy of finite element methods for flow acoustics: I: general theory and application to one-dimensional propagation
TL;DR: In this paper, the effect of the mean flow on the dispersion and amplitude errors present in the discrete numerical solutions of aero-acoustic propagation is examined. But the authors focus on the case of one-dimensional acoustic propagation in which the wave direction is aligned with the average mean flow.
Journal ArticleDOI
Analysis of high-order finite elements for convected wave propagation
TL;DR: In this paper, the performance of high-order finite element methods (FEM) for aeroacoustic propagation, based on the convected Helmholtz equation, is examined.
Journal ArticleDOI

TL;DR: In this article, the acoustic behavior of 3D printed micro-lattices is investigated to assess the impact of defects induced by the Fused Deposition Modeling technique on the parameters of the equivalent fluid medium.
Journal ArticleDOI
Stability and accuracy of finite element methods for flow acoustics. II: Two-dimensional effects
TL;DR: In this paper, the dispersion properties of finite element models for acoustic propagation on mean flows were investigated, and it was shown that isotropic meshes generally reduce numerical error of triangular elements and higher order mixed quadrilaterals are generally less effective than an equivalent mesh of lower order triangles.
Journal ArticleDOI
A full discrete dispersion analysis of time-domain simulations of acoustic liners with flow
TL;DR: A dispersion analysis of the complete numerical model, based on finite-difference approximations, for a two-dimensional model of a uniform flow above an impedance surface provides insight into the properties of the instability in the numerical model and clarifies the parameters that influence its presence.
