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 ...

Modeling Electrochemical Deposition of Aluminum from Ionic Liquids for PCB Applications

S. Loebel1, S. Braun2, M. Becker3, P. Steinert1, A. Schubert1
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

Simulation Based Design of a Bladeless Centrifugal Flow Compressor

Ingo Schaarschmidt1, Philipp Steinert1, Andreas Schubert1
1Chemnitz University of Technology, Chemnitz, Saxony, Germany

The bladeless centripetal flow turbomachinery or disc turbine was invented by Nikola Tesla with the aim to realize a turbine with higher efficiency and simplicity compared to the state of the art at that time. Unlike conventional turbines, the disc turbine does not use rotor blades. ... 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

A Framework for Automated, Data-Driven Digital Twin Generation from Multiphysical Simulation Models

Maximilian Kannapinn1, Oliver Weeger1
1Technical University of Darmstadt, Cyber-Physical Simulation, Darmstadt, Germany

A digital twin is a virtual set of information replicating its physical counterpart at the utmost fidelity. Digital and physical twin benefit from bi-directional data exchange that occurs in real time and over the whole process lifecycle. Until now, experts in the design phase have ... Read More

Development of a Special COMSOL® Interface Based on an Alternative Model for Bentonite Re-Saturation

Michael Kröhn1, Lars Fromme2
1GRS gGmbH, Braunschweig, Germany
2Hochschule Bielefeld – University of Applied Sciences and Arts (HSBI), Faculty of Engineering and Mathematics, Bielefeld, Germany

Bentonite is a versatile material that is, among other things, envisaged in most countries worldwide for use in radioactive waste repositories to protect the waste canisters against groundwater. The thermo-hydro-mechanically (THM) coupled process of bentonite saturation is commonly based ... 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
