Analysis of the Stress and Load Distribution of an Assembled Screw Including Threaded Contact

C. Hollenbeck1
1IMAGINE Engineering GmbH, Bergheim, Germany

There are different possibilities to simulate a bolted joint. If only the connection of parts in an assembly with the stress distribution and surface pressure between the components without the bolt itself is of interest, the thread of the bolt is omitted and only the effect of bolted ...

2I2M, Arts et Metiers Institute of Technology, University of Bordeaux, CNRS, Bordeaux INP, INRAE

Simulation of laser processes are more and more efficient. In some cases, as welding and additive manufacturing, the physical phenomena are complex, multi-physics and multi-phases, thus some assumptions have to be done. For Laser Powder Bed Fusion, a laser beam melts and vaporizes the ... Read More

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 ...

CFD Modelling of Urban Road Tunnels

Marjan Demuynck1, Siegfried Denys1
1University of Antwerp, Antwerp, Belgium

Urban road tunnels offer a promising solution to extend existing road infrastructure while mitigating air pollution and nuisances affecting nearby residential areas. By diverting traffic underground, valuable surface space becomes available to address other urban challenges. However, ... Read More

Challenges in the Simulation of Vacuum Processing Hardware

Juergen Weichart1, Thomas Tschirky1
1Evatec AG, Hauptstrasse 1a, CH-9477 Trübbach, Switzerland

Process Hardware for heating, etching and plasma deposition in vacuum processes on Silicon wafers or glass substrates face challenging requirements due to very shallow and extended structures. Molecular Flow calculations are used to evaluate staggered shields with the aim to protect ... Read More

Combustion Resistance of Fine Metal Parts

2PIMM Laboratory, Arts et Métiers Institute of Technology (Paris), CNRS, CNAM, HESAM University, 151 Boulevard de l’Hôpital, 75013 Paris, France

The presence of oxygen in metal installations can influence their flammability, which leads to frequent combustion ignitions. Various studies have been done to characterize this ignition, in order to classify metals according to their degree of flammability, and to minimize the risk of ... Read More

Common Mode Choke Electromagnetic Simulation

M. Balestrini1
1SCHURTER AG

Common mode chokes are used in electrical circuits to filter out the electromagnetic interference (EMI). The goal of this study is to simulate the impedance of the choke within a range of frequency from 0.01 MHz to 50 MHz. In this simulation model the COMSOL® AC/DC Module with magnetic ... Read More

Comparison of AEL and AEM Electrolyser Technologies

David Martinet1, Christoph Ellert1
1HES-SO Valais-Wallis, Sion, Valais, Switzerland

Alkaline Electrolysis (AEL) technology is known and used in industries for half a century. It is a key technology for large-scale hydrogen production powered by renewable energy for example chemical industries. Flows of 99.999% pure hydrogen up to 20’000 Nm³/h with an electrical power of ... Read More

Complete Design of a High Power Ultrasonic Flow-Cell Reactor with Special Air Cooling System

Lorenzo Spicci1
1Everywave Srl

Ultrasonic flow-cell reactors are used for many industrial applications, where fluid substrate is sonicated in a small region, where very high ultrasonic acoustic power is present. The electromechanical transducer (converter) that drive the sonotrode inside the flow-cell is designed in ... Read More

Computational Modeling of Plasma Using Single-Fluid and Two-Fluid Modeling Approaches

Sai Likitha Siddanathi1, Lars-Goran Westerberg1, Hans O. Akerstedt 1, Henrik Wiinikka 2, Alexey Sepman2
1Luleå University of Technology
2RISE AB

Plasma, a complex fluid consisting of electrons, ions, neutrals, and excited species, exhibits both fluid-like behavior and electrical conductivity due to the presence of charge carriers. Consequently, computational modeling of plasma requires the integration of fluid and electrical ... Read More
