A Validated Finite Element Model for Room Acoustic Treatments with Edge Absorbers
Florian Kraxberger, Eric Kurz, Werner Weselak +3
Porous acoustic absorbers have excellent properties in the low-frequency range when positioned in room edges, therefore they are a common method for reducing low-frequency reverber…
Anisotropic Minimum Dissipation Subgrid-Scale Model in Hybrid Aeroacoustic simulations of Human Phonation
Martin Lasota, Petr Šidlof, Paul Maurerlehner +2
This article deals with large-eddy simulations of 3D incompressible laryngeal flow followed by acoustic simulations of human phonation of five cardinal english vowels /u, i, \texti…
High-Order Non-Conforming Discontinuous Galerkin Methods for the Acoustic Conservation Equations
Johannes Heinz, Peter Munch, Manfred Kaltenbacher
This work compares two Nitsche-type approaches to treat non-conforming triangulations for a high-order discontinuous Galerkin (DG) solver for the acoustic conservation equations. T…
Conservative interpolation of aeroacoustic sources in a hybrid workflow applied to fan
Stefan J. Schoder, Clemens Junger, Michael Weitz +1
In low Mach number aeroacoustics, the well known disparity of scales makes it possible to apply efficient hybrid simulation models using different meshes for flow and acoustics, wh…
Numerical investigation of a deep cavity with an overhanging lip considering aeroacoustic feedback mechanism
Stefan Schoder, Ivan Lazarov, Manfred Kaltenbacher
In modern transport systems, passengers' comfort is greatly influenced by flow-induced noise. In this study we investigate a generic deep cavity with an overhanging lip, mimicking…
Aeroacoustic source term filtering based on Helmholtz decomposition
Stefan Schoder, Manfred Kaltenbacher
Hybrid aeroacoustic methods seek for computational efficiency and robust noise prediction. Using already existing aeroacoustic wave equations, we propose a general hybrid aeroacous…
