One of the major challenges in designing µTEGs is to minimize power loss due to internal resistance (r) of Thermoelectric (TE) materials. To solve this problem we have performed simulation analysis and calculated the internal resistance of eight different TE materials. The internal ... 詳細を見る
Heterogeneous materials with different phases, are conductive and insulating (dielectric), and are physically present in different natural materials as e.g. atmospheric ice. Jonscher’s proposed ‘universal dielectric response’ is not sufficient for such materials, as it only reflects ... 詳細を見る
A hyperelastic seal is pulled over a metal ring in a coffee machine for maintenance reasons. The force needed to pull the hyper elastic seal over the part is too high and should be reduced for maintenance reasons. Using the COMSOL Multiphysics® Structural Mechanics Module, and using the ... 詳細を見る
Thermoelectric materials are one of the most promising materials for future and nowadays energy harvesting devices, as they can convert heat into electricity and vice-versa. The efficiency of thermoelectric materials is related with the figure of merit, ZT. Our work deals with the ... 詳細を見る
Nowadays, spot laser welding is a full-fledged part of industrial manufacturing and is routinely used due to its advantages. It generates very located temperature gradients, and therefore, induces small distortions in the pieces. The COMSOL Multiphysics® software is used to model the ... 詳細を見る
The use of high power microwave energy for ablation of contaminated concrete is a promising technique to speed up the dismantling of nuclear power plants. A coupled simulation using COMSOL Multiphysics® finite element software is performed by solving the electromagnetic wave equation at ... 詳細を見る
LiveLink™ for MATLAB® is used to fit the surface temperature of a battery cell within a COMSOL Multiphysics® model to the temperature measured by a thermal imaging camera. The test bench was designed and built up of ourselves to allow nondestructive thermal diffusivity measurement of Li ... 詳細を見る
Polishing is one of the oldest finishing processes. However, exposure to emissions of crystalline silica dust is high. Some toxicological studies have identified this pollutant as responsible for a particular type of lung cancer, silicosis. Operational solutions are needed for reducing ... 詳細を見る
In this paper, we simulated the heating of a work piece by coupling two heat sources. Concentrated solar energy was applied at the bottom of the work piece, which generated a heat flux from the parabolic solar dish concentrator. Subsequently, induction heating was applied, which ... 詳細を見る
Ionic wind is the gas flow induced by the corona discharge. Ions produced by corona are accelerated by electric field and transfer their momentum to neutral molecules. Using ionic wind one can convert electric energy to kinetic energy of air flow almost directly. The phenomenon of ionic ... 詳細を見る
