Prediction of the Loudspeaker Total Harmonics Distortion Using COMSOL Multiphysics® Software

F. Malbos [1], M. Bogdanski [2], M. Strauss [2],
[1] Harman, Paris, France
[2] Harman Becker Automotive Systems, Straubing, Germany

For automotive applications, simulation methods are used to get the best audio acoustic performance. Because a loudspeaker is a non linear device, the sound pressure in the vehicle includes harmonics which are mainly created by the force factor, suspension stiffness and voice coil ... Mehr lesen

Energy efficiency and harvest, speed and performance, flexibility and portability are key elements for innovation in the current consumer electronics markets. Thermoelectric Generators can convert energy from heat gradients into electricity. Every source of heat from an electronics ... Mehr lesen

Simulation of Microstructured Rolling-Sliding Contacts

M. Weschta[1], S. Tremmel[1], S. Wartzack[1]
[1]Engineering Design, Friedrich-Alexander-University Erlangen-Nürnberg (FAU), Erlangen, Bavaria, Germany

To reduce friction in lubricated tribological contacts, the surfaces of the contacting bodies can be microstructured to improve lubricating conditions. For lower loaded contacts this approach has already reached industrial applications, e.g. the piston-liner contact. For higher loaded ... Mehr lesen

Best Practices in EM Simulation in COMSOL Multiphysics®

M. Olsson [1]
[1] COMSOL AB, Stockholm, Sweden

This session addresses some common challenges in electromagnetic modeling and simulation. The introductory presentation will cover how to pick and choose between a large number of available formulations in three separate modules including the AC/DC Module, RF Module, and Wave Optics ... Mehr lesen

Transformation Optics Simulation Method for Stimulated Brillouin Scattering

R. Zecca [1], P. T. Bowen [1], D. R. Smith [1], S. Larouche [1],
[1] Center for Metamaterials and Integrated Plasmonics and Department of Electrical and Computer Engineering, Duke University, Durham, NC, USA

Stimulated Brillouin scattering (SBS) is a nonlinear phenomenon coupling optical and elastic waves. Traditionally regarded as an undesirable side-effect, it has garnered renewed interest as a platform for investigating slow light, nonreciprocity, and for designing high-performance chip ...

[1]Dipartimento Matematica e Fisica, Università Cattolica, Brescia, Italy
[2]JILA, University of Colorado at Boulder, Boulder, Colorado, United States
[3]Center for Nanotechnology Innovation @NEST, Istituto Italiano di Tecnologia, Pisa, Italy

Ultrafast optical generation of pseudosurface acoustic waves is investigated in hypersonic surface phononic crystals. The thermomechanics is modeled from first-principles to follow the initial impulsive heat-driven displacement in the time domain. Spectral decomposition of the ... Mehr lesen

Fluid-Structure Interaction Modeling of High-Aspect Ratio Nuclear Fuel Plates Using COMSOL Multiphysics®

F. Curtis[1], K. Ekici[1], J. D. Freels[2]
[1]The University of Tennessee, Knoxville, TN, USA
[2]Oak Ridge National Laboratory, Oak Ridge, TN, USA

The High Flux Isotope Reactor at the Oak Ridge National Lab is in the research stage of converting its fuel from high-enriched uranium to low-enriched uranium. One of the areas being explored is the fluid-structure interaction phenomenon due to the interaction of thin fuel plates (50 ... Mehr lesen

Phase Decomposition for Loudspeaker Analysis

R. Christensen [1],
[1] GN ReSound A/S, Copenhagen, Denmark

The vibration of an electrodynamic loudspeaker driver causes a resulting sound pressure. For simple pistonic vibration, there is a simple relationship between the vibration and the sound pressure. For complex vibration patterns, however, different parts of the vibrating surface ... Mehr lesen

Using Multiphysics to Quantify Leakage Rates in New and Rehabilitated Sewer and Water Pipes

C. Hansen [1],
[1] Electro Scan Inc., Sacramento, CA, USA

Traditionally, municipal sewer and water agencies have relied on acoustic data loggers and closed-circuit television cameras to inspect pipes for leaks. In addition, the same legacy techniques have been used to certify new and rehabilitated pipes as watertight. Unfortunately, visually ... Mehr lesen
