Application of the district cooling/heating network design models in the GLN area

François Maréchal, Luc Girardin, Magnhild Kallhovd

This report present the heating and cooling system integration applied in the GLN area, based on a proposed district cooling/heating network design methodology. The cooling load is provided by a mix of direct cooling and refrigeration. To improve the total ...

Application of Photoluminescent Measurement Techniques for Quantitative Assessment of Turbine Film Cooling

Magnus Jonsson

Reduction of the specific fuel consumption of gas turbines can be achieved by maximizing the turbine inlet temperature. However, this requires a detailed understanding of the cooling performance in order to ensure safe and economical operation of the engin ...

Ion irradiation enhances the mechanical performance of metallic glasses

Johann Michler, Manuel Alexandre Pouchon

We demonstrate that irradiation may enhance the plasticity in metallic glasses by increasing the free-volume content via micropillar compression experiments on an ion-irradiated bulk metallic glass (BMG). Results show that irradiation decreases the flow st ...

Soudage laser or-acier

Denis Favez

In jewelry manufacturing, joining dissimilar materials is usually achieved by brazing or soldering, in which the materials comprising the joint are heated to a suitable temperature in the presence of a filler metal having a liquidus below the solidus of th ...

Transient Thermal Model of a Medium Frequency Power Transformer

Alfred Rufer, Irma Villar

Nowadays medium voltage conversion systems, like traction and energy distribution systems, aim to increase power density. Volume, weight and material reduction are gaining the market today. Due to the development of new high power semi-conductor devices a ...

On wire-grid representation of solid metallic surfaces

Marcos Rubinstein, Abraham Rubinstein

This paper deals with the wire-grid representation of metallic surfaces in numerical electromagnetic modeling. We discuss in particular the adequacy of the well known and widely used equal area rule (EAR) to calculate the radii of wire-grid models. We show ...

Process for avoiding cracking in welding

Michel Rappaz, Wilfried Kurz, Jean-Daniel Wagnière

The new welding process avoids cracking in welding, in repair welding or in cladding of parts of metallic alloys which are sensitive to hot cracking. The process is using a first heat source (15), directed to the parts (11, 12) of the metallic alloy formin ...

STUDY AND MODELING OF HOT TEARING FORMATION

Michel Rappaz, Jean-Marie Drezet

As for most of the topics in the field of solidification, Mert Flemings has always pioneered new ideas. While much of the understanding of hot tearing formation was already known about 30 years ago, he devised with Metz an interesting apparatus for studyin ...

Electronic properties and (meta) stability of rapidly quenched Al-Si alloys

Davor Pavuna

Two important effects were found in rapidly quenched Al-Si alloys: (i) the enhancement of the electron-phonon coupling parameter, revealed by the variation of Tc and the slope of thermal resistivity; (ii) the metastability of these crystalline metallic all ...
