Heat Transfer and Phase Change

Simulation of Laser-Excited Surface Acoustic Waves Travelling on a Steel Hemisphere Shell

J. Mäkinen [1], D. Veira Canle [1], R. Blomqvist [1], A. Salmi [1], E. Hæggström [1],
[1] Department of Physics, Division of Materials Physics, University of Helsinki, Helsinki, Finland

Non-contacting guided wave tomography based on laser ultrasonic waves can be used to inspect structures that are inaccessible to traditional ultrasound methods. Such structures could be, chemically or physically hard to reach, e.g. hot metal structures, metal implants inside tissue or ... En savoir plus

The Numerical Challenges in Multiphysical Modeling of Laser Welding with ALE

I. Tomashchuk [1], I. Bendaoud [2], J.-M. Jouvard [1], P. Sallamand [1],
[1] Laboratoire Interdisciplinaire Carnot de Bourgogne, Université de Bourgogne-Franche-Comté, Le Creusot, France
[2] Laboratoire de Mécanique et Génie Civil, Université de Montpellier, France

The interaction of high power laser beam with metallic materials produces a number of interconnected phenomena that represent a serious challenge for numerical modeling, especially for creation of auto-consistent models. Additional difficulty consists in lack of data on materials ... En savoir plus

Simulation of 1D Heat Distribution in Heavy Oil Reservoirs During Steam Injection Process

T. H. Nassan [1],
[1] Freiberg University of Technology, Institute of Drilling Technology and Fluid Mining Engineering, Freiberg, Germany

Enhanced oil recovery (EOR) is expanding worldwide to produce more oil from the existing reservoirs to fulfil the demand of the global consumption, which increases on yearly basis. Thermal methods like steam injection and its variations are the most famous methods applied in heavy oil ... En savoir plus

Thermo-Fluid-Metallurgical Modeling and Parametric Study of Laser-Based Powder Bed Fusion Process

M. Bayat [1], S. Mohanty [1], J. H. Hattel [1],
[1] Department of Mechanical Engineering, Technical University of Denmark, Lyngby, Denmark

Laser-based powder bed fusion (LPBF) is a promising additive manufacturing technology, where metallic parts are produced in a layer-wise manner. At each step, a rapid-moving laser irradiates and subsequently melts predefined zones of a relatively thin layer of fine spherical metal ... En savoir plus

Modeling Solid-Liquid Settling System as a Two-Phase Flow Problem

L. Gyurik [1], A. Egedy [1], Zs. Ulbert [1],
[1] University of Pannonia, Veszprém, Hungary

Sedimentation is a challenging two-phase problem to model and simulate. Many applications in the industry use sedimentation for separation. For example treatment of wastewater often carried out in settling basins. Different types of the sedimentation process include independent and zone ... En savoir plus

Application for Construction and Numerical Analysis of New Melting Elements

L. Strehar [1], S. Kovač [1], D. Janc [1],
[1] ETI d.o.o., Izlake, Slovenia

ETI is one of the world’s leading manufacturers of fuses. Different standard sizes, rated voltages, rated currents and tripping characteristics mean more than 750 different types of products. Additionally, our customers sometimes require fuses specifically designed for their needs. Our ... En savoir plus

Simulating Approaches for Heating Process in Continuous Furnaces

G. Petrone [1], R. Sinatra [1], C. Barbagallo [1],
[1] BE CAE & Test, Italy

Heating of pieces evolving in tunnel furnaces is an argument of high interest in several industrial processes such as thermal treatment of metals, glass production and food industry.Because of pieces move into the furnace, heat flux they receive from fixed heat sources is variable in ...

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 ... En savoir plus

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 ... En savoir plus
