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

Simulation of Through Air Drying in Tissue Paper in a Papermaking Process

K. Rezk1, B. Sjöstrand1
1Institution of engineering and chemical sciences, Karlstad, Sweden

Water removal during paper and board manufacturing is an intensive energy process. The dewatering process generally consists of four stages wherein the last stage is comprised by thermal drying in where remaining water in fibres are evaporated on steam-heated cylinders. The thermal ... Read More

An Analysis of the Synchronous Transport Phenomena Involved in Pasta Drying Process

G. Adduci1, E. Manoli2, E. Cardaropoli2, G. Coppola1, F. Petrosino1, S. Curcio1
1DIMES, Università della Calabria, Cosenza, Italy
2Barilla G. e R. Fratelli, Parma, Italy

This work is focused on the development of a physical-mathematical model capable of predicting the temperature and water content fields within a pasta sample which is exposed to a stream of drying air flowing under turbulent conditions. Therefore, the equations concerning the transfer of ... Read More

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

Numerical Modeling of Bentonite Erosion due to Sedimentation in Sloping Fractures

Virginia Cabrera1, Arnau Pont1, Andrés Idiart1, Patrik Sellin2
1Amphos 21 Consulting S.L., Barcelona, Spain
2SKB, Solna, Sweden

The study of bentonite erosion mechanisms in fractures is a problem of maximum interest to understand the long-term performance of the engineered barrier in deep geological repositories of spent nuclear fuel. In this context, erosion due to shear by seeping water, sedimentation due to ... 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

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 ... Read More

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

S. Wiesinger1, W. Wiedemair1
1OST - University of Applied Sciences Eastern Switzerland, Buchs SG, St. Gallen, Switzerland

Technical advancements in miniaturization in the last decades have, among others, brought forth the technology of so called “Lab-on-a-Chip” (LOC) systems. These systems provide the possibility to automate and accelerate certain laboratory processes, e.g., biomedical diagnostics, on the ... Read More
