Heat Transfer and Phase Changex

Modeling Convective Heat Transfer in the Porous Active Layer of an Alpine Rock Glacier

J. Wicky [1], M. Scherler [1], Ch. Hauck [1],
[1] Alpine Cryosphere and Geomorphology Group, University of Fribourg, Switzerland

Permafrost is defined as soil which remains frozen for at least two consecutive years. In the Swiss Alps, it is a widespread phenomenon with a great impact on the landscape particularly regarding natural hazards. The occurrence of permafrost is not only influenced by meteorological ...

Magneto-Mechanical-Thermal Couplings for the Pulsed Magnetic Technology with Single-Turn Coils

O. Maloberti [1], P. Sansen [1], D. Jouaffre [2], D. Haye [2],
[1] ESIEE Amiens, France
[2] PFT Innovaltech, France

Single turn coils produce AC and transient magnetic fields in pulsed magnetic technologies for which magneto-harmonic and transient magnetic analysis can be primarily performed. We suggest studying one single turn coil example made of a conducting massive coil, an optional conducting ... Per saperne di più

Optimization of Static Magnetic Fields for Neutron Science

M. Schneider [1],
[1] SwissNeutronics AG, Klingnau, Switzerland

Neutrons are a powerful research tool and provide scientists unprecedented insight into the structure and properties of materials. Experiments with spin-polarized neutrons demand sophisticated neutron optical devices embedded in tailored static magnetic fields. For this study we ... Per saperne di più

Design of an AC Transformer in the MHz Range

D. Martinet [1], Ch. Ellert [1],
[1] University of Applied Sciences Western Switzerland (HES-SO Valais-Wallis), Institute of Systems Engineering, Sion, Switzerland

Due to the Paschen law the ignition voltage for plasma increases proportionally to electrode gap and pressure between electrodes. Atmospheric plasmas operating in the MHz range, being of great interest for surface treatment, require therefore high voltage power supplies, even though in ... Per saperne di più

Experimental Setup to Investigate the Liquid Water Content in Snow

A. Coulin [1],
[1] SLF Davos, ETH Zurich, Switzerland

Snow can exist in a wide range of temperatures. Its behavior changes especially around its melting point. A better understanding for wet snow is essential for snow pack stability, the effect of water percolation and friction between ski and wet snow surface. Technical details about ...

COMSOL® Simulation of Flash Lamp Annealing for Battery Electrodes Fabrication

C. Cherkouk [1], L. Hell [1], M. Zschornak [1], T. Leisegang [1], D. C. Meyer [1],
[1] Institute for Experimental Physics, TU Bergakademie Freiberg, Freiberg, Germany

Flash lamp annealing (FLA) is a modern annealing technique in the range of milliseconds, which is predestinated for roll-to-roll fabrication of battery electrodes. All-solid-state batteries are the next generation battery concepts that are currently being envisaged among both the ... Per saperne di più

Numerical Prototyping of Locally Heated Digital Microfluidic Devices

C. Ozen [1], G. Sathyanarayanan [1], S. Cito [2], T. Sikanen [1],
[1] Faculty of Pharmacy, Drug Research Programme, University of Helsinki, Helsinki, Finland
[2] Department of Mechanical Engineering, Rovira i Virgili University, Tarragona, Spain

An alternative approach to integration of a local heat source with the digital microfluidic (DMF) platform by attaching inkjet-printed silver microheaters to the bottom plate was recently introduced (Sathyanarayanan et al., MNE 2017). This approach allows more degrees of freedom to the ... Per saperne di più

Numerical Optimization of Active Heat Sinks Considering Restrictions of Selective Laser Melting

F. Lange [1], C. Hein [1], C. Emmelmann [1],
[1] Fraunhofer Institution for Additive Production Technologies IAPT, Hamburg, Germany

Parametric and topology optimization approaches are widely used techniques for performance improvement of components in terms of various objectives. Especially topology optimization often leads to complex geometries that are difficult or impossible to produce by conventional ... Per saperne di più

Simulation of an Electrically Heated Carbon Fibre Fabric

L. Fromme [1], H. Funke [1], J. Stückemann [1], P. Tschöke [1],
[1] Bielefeld University of Applied Sciences, Faculty of Engineering and Mathematics, Bielefeld, Germany

For an increasing portion of various construction components carbon fibre reinforced plastic is used, since this material combines desirable properties as high stability and low weight. Carbon fibre reinforced plastic consists of carbon fibre fabric which is drenched in resin that then ... Per saperne di più
