Modeling of a Vapor Chamber Using COMSOL Multiphysics®

Melissa Rodriguez Vargas 1, Bruno Chiné1
1School of Materials Science and Engineering Costa Rica Institute of Technology, Cartago, Costa Rica

High power consumption chips have already become a major challenge for modern processors causing low thermal performances. Existing thermal solutions are not able to solve these high temperature issues efficiently. Two-phase cooling devices such as heat pipes and vapor chambers have ... 詳細を見る

Modeling of Delayed Desorption in Activated Carbon Filter Systems for Air Purification Applications.

K. Schoofs1
1UAntwerpen

Activated carbon filtration has proven to be a reliable method to clean indoor air. In such a system, air, contaminated with VOCs, is led through the filter where the contaminants are adsorbed onto the filter. However, for the long term stability of the air purification system, it is ... 詳細を見る

Modeling PCB Based Inductive Position Sensors with the COMSOL® AC/DC Module

Seriem Sid-Ahmed1, Lorenzo Lugani1
1Melexis Technologies SA, Bevaix, Switzerland

The growing adoption of electric vehicles has led to increased exposure of cars to stray magnetic fields. To address this issue, inductive position sensors have emerged as a viable solution due to their inherent immunity to stray magnetic fields. Widespread adoption of the inductive ... 詳細を見る

Modeling the Indoor Removal of Volatile Organic Compounds (VOCs) by Botanical Biofiltration

Allan A. Alvarado-Alvarado1, S. Denys1
1Sustainable Energy, Air and Water Technology Research Group (DuEL), Department of Bioscience Engineering, University of Antwerp, Antwerp, Belgium

Historically, indoor air quality (IAQ) has received less attention than outdoors, although people spend >90% of their time in the indoor environment. A major group of indoor air pollutants is volatile organic compounds (VOCs), which are detrimental to human health even at low ... 詳細を見る

Modelling of Custom-Made Photocatalytic Wind Tunnel for Air Purification by Solar Photocatalysis

Benjamin Radetić1, Lucija Radetić1, Ivana Grčić1
1University of Zagreb, Faculty of Geotechnical Engineering, HR-42000 Varaždin, Croatia

Heterogeneous photocatalysis an advanced oxidation process (AOP) which in combination with a catalyst and UV irradiation completely mineralizes organic pollutants from water or gases into harmless compounds such as carbon dioxide (CO2) and water (H2O). Photocatalysis as a process is ... 詳細を見る

Modelling of Desaturation/Resaturation of Geological Repository Barriers Considering Gas Generation

A. Narkuniene1, P. Poskas1, R. Kilda1
1Lithuanian Energy Institute, Kaunas, Lithuania

Geological repository for highly radioactive waste disposal is a system of engineered and natural barriers. The objective of this system is to contain and isolate waste and protect the environment and humans from ionizing radiation. For the evaluation of performance of engineered ... 詳細を見る

Modelling of Interfacial Charges and Kinetics of Dye-Sensitized Solar Cells Photoanodes

Wasiu Abidemi Hamzat1, Dmitry Momontenko1, Gunther Wittstock1
1Chemistry Department, Carl von Ossietzky University of Oldenburg, D-26111, Germany

In this study, we attempted to develop a simulation to better understand the kinetic of the dye regeneration process in photoanodes of dye-sensitized solar cells (DSSCs). For that purpose, a numerical model was developed using finite element simulation in COMSOL Multiphysics®. The ... 詳細を見る

Modelling the Composition Gradient in Ni-Mn-Ga Single Crystal Grown by Floating Zone Method

Denys Musiienko1, Ross H. Colman2
1Institute of Physics of the Czech Academy of Sciences, Prague, Czech Republic
2Charles University, Prague, Czech Republic

Re-crystallisation of Ni-Mn-Ga Heusler alloys in a floating zone (FZ) optical furnace is a complex problem that depends not only on the compositions of the master alloy and a seed crystal but on the growth speed and evolution of the molten zone shape during the crystal growth process. We ... 詳細を見る

Multiphysical Optimization of the Next Generation of Energy Efficient High Temperature Furnaces

Karl-Heinz Leitz1, Bernhard Valentini1
1PLANSEE SE, Metallwerk-Plansee-Straße 71, 6600 Reutte, Austria

To achieve the goals of the Paris Agreement and limit global warming below 2 K compared to pre-industrial level, significant energy savings in all fields of industries will be required. One example of energy intensive processes in industrial fabrication is heat treatment. The applied ... 詳細を見る
