Benchmarking COMSOL - Part 2: CFD Problems

Darrell Pepper
Professor of Mechanical Engineering,
University of Nevada - Las Vegas

Using COMSOL 3.5a, a set of benchmark problems requiring the use of the COMSOL Computational Fluid Dynamics (CFD) module has been simulated. Several of the problems include fluid-heat transfer interactions (Computational Heat Transfer - CHT). The four problems are:

  1. flow over a 2-D...

Benchmarking COMSOL Multiphysics 3.4

Darrell Pepper
Professor of Mechanical Engineering
Director of the Nevada Center for Advanced Computational Methods (NCACM)
University of Nevada, Las Vegas
Las Vegas, NV

In this presentation, four benchmark problems are tested using COMSOL Multiphysics as well as other commercial software packages, comparing their performance. This is done for fluid-structure interaction, fully coupled electronic current conduction with thermal and structural analysis,...

Finite element models for the solution of underwater acoustics problems

Mario Zampolli
NATO Undersea Research Centre
La Spezia, Italy

Acoustic waves are used in SONAR systems for the detection and classification of objects which may be swimming in the water column, proud on the seafloor, or buried below the sediment. In some applications, such as low frequency detection and classification of structurally complex objects immersed...

Hydraulic Design of Activated Sludge Tanks with CFD

A. J. Bosma, and B. A. Reitsma
Tauw bv, Deventer, The Netherlands

The hydraulic design of wastewater treatment plants (WWTP) is usually based on general guidelines and experience. Research and development in this field is mainly focused on understanding and improvement of the biological processes.

In this article we present modeling of the activated...

Finite Element Approach for 2D Micromagnetic Systems

H. Szambolics1, L. Buda-Prejbeanu2, J. C. Toussaint1,2, and O. Fruchart1
1Institut Néel, CNRS-INPG-UJF, Grenoble, France
2Laboratoire SPINTEC, CEA-CNRS-INPG-UJF, Grenoble, France

The imbalance between the four fundamental magnetic interactions (the magneto-crystalline anisotropy, the exchange and magnetostatic interactions, and the Zeeman coupling) is responsible for a very large diversity of magneticbehaviors that researchers try to explore anduse for technical...

Simulation of Heat and Momentum Flow in a Quartz Mercury-filled HID Lamp in Vertical Operation

Dreeben, T.
OSRAM SYLVANIA

FEMLAB is used to provide a benchmark simulation for a classical problem in high-intensity discharge lighting: the pure mercury-filled quartz HID (high-intensity discharge) lamp. A steady 2-dimensional axi-symmetric formulation estimates the operating temperatures, electrical potential, and gas...

Virtual Homogeneous Isotropic and Real Unhomogeneous Anisotropic Metamaterials

Akalin, T.
IEMN (Institut d’Electronique de Microélectronique et de Nanotechnologie), CNRS UMR 8520, Dpt DHS, USTL (Université des Sciences et Technologies de Lille)

Characteristics on metamaterials and potential applications are presented with the FEMLAB® software simulations results. By definition, metamaterials are materials which exhibit properties which do not exist naturally. Another point is that metamaterials are associated with the negative...

Modelling of Thermal Stresses in Industrial Continuous Casting Processes

Åberg, J., Vynnycky, M., Fredriksson, H.
KTH/Metallernas Gjutning, Stockholm, Sweden

This paper reports on progress in the implementation of COMSOL Multiphysics 3.2 to model thermal stresses in a three-dimensional solidifying shell, as occurs typically in the industrial continuous casting of copper, copper alloys and steel. Computer memory requirements prohibit a direct 3D...

Grain Boundary Migration Model in Copper Interconnects

Tim Cale, Daniel Bentz, and Max Bloomfield, RPI

We discuss the use of 3D grain continuum modeling to study grain boundary migration driven by differences in strain energy density. COMSOL Multiphysics is used to compute stresses and strain energy densities in polycrystalline structures caused by temperature changes. We treat each grain as a...

Multibody Contact Analysis of an Rzeppa CV-Joint

L. Armellin1, F. Gatelli1, and G. Tanghetti1

1R&D Department, Metelli S.p.A., Cologne, BS, Italy

Ball joints are widely used in many applications. This paper describes the contact and kinematic analysis of an Rzeppa type constant-velocity joint (CV-joint). Starting from a conveniently simplified 3D model, at fixed...
