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. ... Mehr lesen

D. Peyrow Hedayati1, G. Kahlmeyer1, M. Kucher1, R. Böhm1
1Faculty of Engineering, Leipzig University of Applied Sciences, Leipzig, SN, Germany

Structural Supercapacitors (SSC) are an important group of Multifunctional Energy Storage Composites (MESC) and can potentially play a significant role in lightweight design of aerospace and automotive applications [1]. Therefore, it is important to build accurate models based on the ... Mehr lesen

3D Numerical Simulation of Resistance Sintering for Electrical Contact Applications for Breakers

J. AMOVIN-ASSAGBA1, V. BRUYERE2, P. NAMY2, C. DURAND1, S. ROURE1
1SCHNEIDER ELECTRIC, 31 Rue Pierre Mendes France, EYBENS, FRANCE
2SIMTEC, 5 Rue Felix Poulat, GRENOBLE, FRANCE

In circuit breakers, short-circuit breaking involves extreme conditions linked to the presence of an intense electric arc. This requires the use of specific electrical contacts consisting of a contact tip and its support. SCHNEIDER ELECTRIC uses the resistance sintering technique for the ... Mehr lesen

Modeling of Thermal Load and Electric Fields in Microfocus X-Ray Tubes

Dr. Vladimir Burlaka1, Thorsten Fröba1
1X-RAY WorX GmbH, Siemensstraße 26, 30827 Garbsen, Germany

The thermal load on the system components is one of the technical problems in the development of microfocus X-ray tubes. To improve their stability in long-term use, it is important to understand the physical phenomena and their influence on the system stability and filament lifetime. To ... Mehr lesen

Interaction of the Laser with the Material Modelling of the Micro-Lenses Creation

P. Janicek1, P. Kutalek1, J. Schwarz1, J. Smolik1, P. Knotek1
1Faculty of Chemical Technology, University of Pardubice, Czech Republic

Micro-lenses with potential applications in optics on the surface of the various heavy-metal oxide glasses were created and studied experimentally [1-2]. Laser direct writing using continuous-wave laser emitting at 447 nm was successfully performed [2]. The aim of this study is to ... Mehr lesen

Heat Transfers and Solid Mechanics in Microarchitectured Materials Using Periodic Homogenization

F. Viry1, J.-D. Wheeler1, P. Namy1
1SIMTEC, Grenoble (France)

Microarchitectured materials are generally made of different compounds bound at the microscopic level using a periodic pattern. This results in a macroscopic material with new properties arising from each of the individual compound properties and the way the microarchitecture binds them. ... Mehr lesen

Modeling of Thermal Expansion of a Material During its Cooling Using COMSOL Multiphysics®

A. CLARISSOU1, V. BRUYERE2, P. NAMY2, I. CRASSOUS1
1FRAMATOME, 60 Avenue Paul Girod, 73400 Ugine France
2SIMTEC, 5 rue Felix Poulat, GRENOBLE, FRANCE

In metallurgy, the use of numerical models is popular because of the many coupled physical phenomena that occur during the various processes. For instance, the resulting shape and metallurgical state of a material are very sensitive to changes in temperature. The drop in temperature of ... Mehr lesen
