Bubble Detachment from the Surface of a (Photo)Electrode

Feng Liang1, Fatwa F. Abdi1
1Institute for Solar Fuels, Helmholtz-Zentrum Berlin für Materialien und Energie GmbH, Hahn-Meitner-Platz 1, 14109 Berlin, Germany

Many (photo)electrolytic devices involve the generation of bubbles (e.g., hydrogen, oxygen). In these devices, bubble coverage on the surface of the electrode not only decreases the active area, but also induces optical loss.[1,2] Efforts in understanding the bubble detachment process ...

1Professorship Micromanufacturing Technology, Chemnitz University of Technology, Chemnitz, Germany
2Fraunhofer Institute for Electronic Nano Systems ENAS, Chemnitz, Germany
3NB Technologies GmbH, Bremen, Germany

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

Degassing of PP Pellets in a Silo: Keeping C9 Concentrations Below the Lower Explosion Limit

R. Wesselink1
1Demcon Multiphysics, Enschede, The Netherlands

When polypropylene (PP) is produced it contains impurities in the form of dissolved gasses. These gasses can be removed by heating the material (in the form of pellets in a silo) and flushing with plenty of fresh air. However, one of the gasses is C9, which is flammable. We built a model ... Read More

Indoor Thermal Analysis of a Storehouse

R. Sinatra1, S. Cagliari1, A. Barbagallo1, G. Petrone1
1BE CAE & Test S.r.l., Viale Africa 170 - Sc.A, 95129, Catania, ITALY

The aim of this study is to evaluate the airflow thermal distribution inside a storehouse in different operational conditions. A warehouse of 12,600 m3 in volume is considered for fluid-dynamical and thermal analysis. Coupled Navier-Stokes and energy equations are solved considering or ... Read More

Using of General Extrusion Operator in Heat Transfer Applications

A. Barbagallo1, R. Sinatra1, S. Cagliari1, G. Petrone1
1BE CAE & Test S.r.l., Viale Africa 170 - Sc.A, 95129, Catania, ITALY

In this paper, the COMSOL Certified Consultant BE CAE & Test shows as the general extrusion operators can be successfully used to simulate thermal transfers in an industrial rotating furnace. Heat transfer in translating and rotating furnaces is a topic of high interest in several ... 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

Simulation of the Arc Motion in Low-Voltage Surge Protection Devices

Margarita Baeva1, Martin Hannig2, Ralf Methling1, Dirk Uhrlandt1, Diego Gonzalez1, Arnd Ehrhardt2
1Leibniz Institute for Plasma Science and Technology, Greifswald, Germany
2DEHN SE + Co KG, Neumarkt, Germany

Nowadays, surge protection devices are widely used in electrical grids to suppress over voltages during transient conditions caused by voltage surges and to prevent damages of industrial or household devices. The working principle is based on the initiation of an arc with a burning ... Read More

Simulation of an Under Lake Infrastructure for Capture and Storage of Solar Energy (ULISSE)

Rozsnyo Roland1, William van Sprolant2, Daniel Bello-Mendes1
