Thermo-hydraulic analysis of the cool-down of the EDIPO test facility

The first cool-down of the EDIPO (European DIPOle) test facility is foreseen to take place in 2011 by means of the existing 1.2 kW cryoplant at EPFL-CRPP Villigen. In this work, the thermo-hydraulic analysis of the EDIPO cool-down is performed in order bot ...

Test results of the 18 kA EDIPO HTS current leads

Pierluigi Bruzzone, Markus Jenni, Manuel Holenstein, Rainer Wesche, Martin Vogel, Stephen Alfred March, Félix Roth, Roland Felder

For the new test facility EDIPO (European DIPOle), to be hosted by CRPP, two 18 kA HIS current leads were manufactured and successfully tested. The HTS module, made of AgMgAu/Bi-2223 tapes, is cooled only by heat conduction to the cold end, while the coppe ...

Two-phase free-surface fluid dynamics on moving domains

Thomas Zimmermann, Matthias Preisig

We develop in this paper a model for the numerical simulation of free surface debris- and mudflows, described as a mixture of two viscous phases A Lagrangian approach with finite element approximation and regular remeshing is adopted in this paper. The pro ...

Study and simulation of different scanning strategies in SLM

Rémy Glardon, Jamasp Jhabvala, Eric Boillat, Thibaud Antignac

In the SLM process, one has to balance between power and scan speed. When small scan speed is used, thermal gradients are important and local solidification can lead to cracks. On the other hand, when high speed is used, the power has to be huge and phenom ...

Numerical modeling of laminar annular film condensation for different channel shapes

John Richard Thome, Stefano Nebuloni

This paper presents a theoretical and numerical model to predict film condensation heat transfer in mini and micro-channels of different internal shapes. The model is based on a finite volume formulation of the Navier-Stokes and energy equations and it inc ...

Numerical Modeling of Annular Laminar Film Condensation in Circular and Non-Circular Micro-Channels under Normal and Micro-Gravity

Stefano Nebuloni

A theoretical and numerical model to predict film condensation heat transfer in mini, micro and ultra micro-channels of different internal shapes is presented in this thesis. The model is based on a finite volume formulation of the Navier-Stokes and energy ...

Part load flow in radial centrifugal pumps

Olivier Braun

Centrifugal pumps are required to sustain a stable operation of the system they support under all operating conditions. Minor modifications of the surfaces defining the pump's water passage can influence the tendency to unstable system operation significan ...

Scientific Computing For Aluminum Production

Jacques Rappaz, Marco Picasso, Gilles Steiner, Thomas Hofer

Numerical simulation in aluminum production envolves many different topics, this paper is dedicated to some aspects of two of them. In the first part, a numerical approach for the computation of the motion of the fluids in an electrolitic cell is presented ...

Discontinuous Galerkin method applied to fragmentation of heterogeneous materials

Jean-François Molinari, Sarah Levy, Raul Radovitzky

Since it generates a multitude of interacting cracks, the computational modeling of fragmentation requires special attention. The discontinuous Galerkin formulation provides an efﬁcient scalable framework to simulate non-linear dynamics of spatially discon ...

Modelling Coupled Mechanics, Moisture and Heat in Pavement Structures

Lyesse Laloui

Different physical problems have been analysed in the preceding {chapters}: they relate to water transfer, to heat transfer, to pollutant transfer and to mechanical equilibrium. All these problems are governed by differential equations and boundary conditi ...
