While copper remains the dominant material for conduction paths in printed circuit board (PCB) applications, both technological and economic reasons have been motivating research on substituting copper with aluminum (Al). Despite its 60 % higher specific electrical resistance, aluminum ... Read More

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 ... Read More

Modeling of Acoustically Induced Rapid Mixing Processes in Microchannels Using Acoustic Streaming

2IME Process Metallurgy and Metal Recycling, RWTH Aachen University, Aachen, Germany

This work, which is done in the framework of the SisAl Pilot EU project, presents the use of the COMSOL Multiphysics® software for simulating an ensemble averaged electric arc in a laboratory-scale electric arc furnace. The SisAl Pilot project aims at optimising the silicon production in ... Read More

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 ... Read More
