Acta Acustica: Achievements 2025 and State of Art

Manfred Kaltenbacher, Thierry Scotti, Mathieu Gaborit, Selina La Barbera et autres

2025 has been a very exciting year for Acta Acustica.After its foundation by the European Acoustics Association (EAA) in 1993, the European journal has gone through major evolutions and since 2020, it has turned into a full Open Access (OA) journal in …

Sound source identification for tire-pavement-interactions based on an inverse scheme

Jonathan Nowak, Manfred Kaltenbacher

In this publication, we present sound source localization results at the rolling tire, mounted to a measurement trailer. A recently developed Inverse Scheme, combining microphone measurements and Finite Element simulations is applied at discrete frequencies to identify sound sources during the tire-pavement …

Mode-oriented finite-element model updating for thin-walled ducts via point-wise time-harmonic simulations

Patrick Heidegger, Felix Czwielong, Andreas Wurzinger, Christoph Heigl et autres

Unspecified material properties and boundary conditions are common culprits for inaccurate vibro-mechanical finite-element predictions of thin-walled ducts. Updating inaccurate modeling assumptions can be challenging, especially when damping is non-negligible. This paper proposes a mode-oriented model-updating workflow that utilizes time-harmonic simulations evaluated only …

The CREATOR Project: Towards a Computational Electric Machine Laboratory

Sebastian Schöps, Annette Muetze, Herbert De Gersem, Herbert Egger et autres

The Collaborative Research Centre TRR 361/F90 CREATOR (2022-2030) aims at establishing a new paradigm for the simulation-driven design of electric machines. Increasing demands on efficiency, power density and sustainability require the integration of multiphysical effects, advanced materials and complex geometries into the …

FAN 01 Benchmark: Low pressure Axial Fan in a short Duct

Florian Krömer, Clemens Junger, Stefan Becker, Manfred Kaltenbacher et autres

The case consists of a generic axial fan for industrial applications. Provided measurement data include instationary pressure probes in the rotor's tip gap, distributions of velocity and turbulent kinetic energy gained by laser Doppler anemometry, as well as acoustic results gained by …

An Overview of the Benchmark Case for the Aeroacoustics and Structural Acoustics of an Enclosed Centrifugal Fan

Felix Czwielong, Patrick Heidegger, Manuel Zaragoza Lauber, Christoph Heigl et autres

As part of a joint research project between the Institute of Fluid Mechanics (LSTM) and the Institute of Fundamentals and Theory of Electrical Engineering (IGTE), an international benchmark case for fluid–structure–acoustic interaction was developed. The research focused on an enclosed centrifugal fan, …

A Practical Approach to Determine Lumped‐Element Parameters From a Finite‐Element Three‐Phase Transformer Model

Alexander Sauseng, Klaus Roppert, Peter Hamberger, Manfred Kaltenbacher

ABSTRACT This contribution presents a practical approach for determining the parameters of a topological lumped‐element (LE) three‐phase transformer model in a shell‐type configuration from a two‐dimensional finite‐element (FE) simulation. Based on the observations of the magnetic flux density from the FE simulation …

A Comparative Analysis of an H‐Formulation for the 3‐D Magnetostatic and Magnetoquasistatic Case Considering Hysteretic Effects

Lukas Domenig, Klaus Roppert, Manfred Kaltenbacher

ABSTRACT Finite element formulations using the magnetic vector potential are numerically inefficient for modelling 3‐D magnetic hysteresis, as they rely on computationally expensive inverse material models. This article presents a robust and efficient ‐formulation that overcomes this limitation by incorporating the direct …
