Implementation of an Active Fluid Cooling Design in a 48 V High-Power Battery Module

Z. Wu [1], A. Stawarski [2], H. Kemper [2],
[1] Energy Storage Systems, FH Aachen - University of Applied Sciences, Aachen, Germany; RWTH Aachen University, Aachen, Germany
[2] Energy Storage Systems, FH Aachen - University of Applied Sciences, Aachen, Germany

Individual batteries have their own operational temperature ranges, which shall be respected to avoid both damaging of the cells and shortening of the cycle life. In terms of the Li-Ion cells, many of them do not function well at higher temperatures. Therefore, a better understanding of ... En savoir plus

Thermo-Fluid Dynamics FEM Simulation of Advanced Water Cold Plates for Power Electronics

N. Delmonte[1], F. Giuliani[1], P. Cova[1]
[1]Dipartimento di Ingegneria dell'Informazione, Università degli Studi di Parma, Parma, Italy

Introduction: Power electronic converters such as those for High Energy Physics Experiments (HEPEs) must operate in thermally hostile environment. Heat generated by electronics components must be conveniently dissipated to ensure electrical performances and improve reliability. Due to ... En savoir plus

Natural Convection Effects on the Solidification in Cylinders at Different Filling Percentages

R. Bourisli [1], A. Alshayji [1],
[1] Kuwait University, Kuwait City, Kuwait

The solidification of a fluid in a partially-filled circular cylinder is encountered in a number of industrial processes and in the oil and gas sector. The characteristics of the process depends on various fluid and geometrical parameters. In the current study, a fluid with temperature ... En savoir plus

[1] ArcelorMittal, Montataire, France
[2] Laboratoire Interdisciplinaire Carnot de Bourgogne, Université Bourgogne Franche Comté, France

Laser Welded Blank solutions enable to reduce vehicles weight and to optimize their crash performances by means of simultaneous tuning of different grades and thicknesses. The present work aims to characterize numerically and experimentally materials mixing during laser welding. For ... En savoir plus

Numerical Analysis of the Flow Structure in the Continuous Casting Two-strand Tundish

M. Warzecha [1], J. Jowsa [1], A. M. Hutny [1], P. Warzecha [1], T. Merder [2]
[1] Czestochowa University of Technology, Czestochowa, Poland
[2] Silesian University of Technology, Katowice, Poland

Calculations were carried out for the water model of the investigated tundish, represented on a scale 1:3. Numerical calculations enable to estimate the fluid flow velocities, pahtlines and other parameters. Calculations were done for two different grids. Based on the results, the flow ... En savoir plus

Simulation of Surface Chemical Reactions in a Monolith Channel for Hydrogen Production

N. Pacheco[1], D. Pavone[1], K. Surla[1], J. Houzelot[2], and E. Schaer[2]
[1]IFP-Lyon, Solaize, France
[2]ENSIC, Solaize, France

This paper intends to show a model of a monolithic reactor for the autothermal reforming process (ATR), a process that uses hydrocarbons to produce H2. The ATR chemical reactions take place on the surface of monolith channels coated with a catalyst. The isothermal ATR reactor is modeled ... En savoir plus

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.
