Finite Element Evaluation of the Strength of Silicide-Based Thermoelectric Modules

A. Miozzo [1], S. Boldrini [1], A. Ferrario [1], M. Fabrizio [1],
[1] Institute of Condensed Matter Chemistry and Techologies for Energy - National Research Council of Italy, Padova, Italy

Silicide-based thermoelectric modules (TEMs) for power generation operate at mid-high temperature range. In the operating conditions, thermal stresses in materials with different coefficient of thermal expansion may reduce the mechanical strength of the modules. In this work, a finite ...

Thermal Conductivity of Composites: How COMSOL Revealed an Omission in a Classical Paper

P. Berne [1],
[1] University Grenoble Alpes, Grenoble, France

The initial motivation for this work was to explore the relationship between the shape of particles and the thermal conductivity of nanofluids or nanocomposites containing them. Since the possibility for manufacturing exotically-shaped particles is ever growing, it was thought useful to ... En savoir plus

INTRODUCTION Our group at ORNL started using COMSOL Multiphysics® software shortly after version 3.0 was released in the Spring of 2004. After 11 years and several releases, the application usage has grown along with number of licenses we are responsible for. This paper will broaden ... En savoir plus

Damping in Dense Gas Acoustic Structure Interaction

J. P. M. Smeulers [1], H. P. Pereboom [1], N. González Díez [1],
[1] TNO, Delft, The Netherlands

Large centrifugal compressors, which are commonly applied in the oil and gas and in the process industry, may fail due to vibrations of the impeller. These vibrations are induced by pressure pulsations in a compressor stage. These vibrations can be especially strong in so-called dense ... En savoir plus

Simulation and Design of an Oven for PET Blow Molding Machines

M. Mor[1], C. Seneci[1], V. Zacché[1], C. Remino[1], G. Petrogalli[1], D. Fausti[1]
[1]Polibrixia, Brescia, Italy

This paper presents the study and design of a new generation oven for PET blow-molding machines. The design faced several technical challenges such as: the temperature distribution in the critical areas, the sharp curvature radius, the high PET thermal inertia and the presence of ...

High Frequency Magnetohydrodynamic Calculations in COMSOL

N. Kleinknecht, and S. A. Halvorsen
Teknova AS
Kristiansand, Norway

In many metallurgical processes metals are (heated and) stirred by an oscillating external magnetic field. The magnetic field induces electric currents in the metal and the currents interact with the magnetic field to create a force, the Lorentz force. For high frequencies induction only ...
