Modeling of Transport Phenomena in Laser Welding of Steels

A. Métais [1], S. Matteï [2], I. Tomashchuk [2], S. Gaied [1]
[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

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

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

Design and Simulation of Piezoelectric Ultrasonic Micro Motor

P. Patel[1], P. Manohar[1]
[1]Electrical and Electronics Department, M. S. Ramaiah Institute of Technology, Bangalore, Karnataka, India

Micro machined motors are a recent development in the domain of electrical machines. Compared to the conventional electromagnetic motors, micro machined motors offer high torque at lower speed, and are compact in nature. This makes them suitable for applications in the field of ... En savoir plus

Multiphysics Modeling of a Metal Foam

B. Chinè [1][3], M. Monno[2]
[1]Laboratorio MUSP, Macchine Utensili e Sistemi di Produzione, Piacenza, Italy
[2]Politecnico di Milano, Dipartimento di Meccanica, Milano, Italy
[3]Instituto Tecnologico de Costa Rica, Cartago, Costa Rica

Introduction: In metal foams production, nucleated gas bubbles expand in a heated metal in a mold, then the foam cool and solidify. Thereby energy, mass and momentum transfer mechanisms are present simultaneously in the system and must be taken into account. Metal foam (Figure 1) can be ... 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

Multiphysics Simulation of Ion Concentration Polarization Induced by Nanoporous Membranes in Dual Channel Devices

M. Jia, M. Kim, T. Kim [1]
[1] Ulsan National Institute of Science and Technology, Ulsan, Korea

ICP phenomenon has been widely used for fabricating microfluidic devices of pre-concentration, micromixing and desalination. However, theoretical research and simulation of ICP have not been carefully dealt with. We provide a multiphysics simulation of a DC-ICP device based on ... En savoir plus

CAE-Based Design and Optimization of a Plasma Reactor for Hydrocarbon Processing

C. Soares [1], F. A. Cassini [1], N. Padoin [1],
[1] Universidade Federal de Santa Catarina, Florianópolis, SC, Brasil

Plasma reactors can be applied to the conversion of waste, biomass and fuels to synthesis gas (mixture of hydrogen and carbon dioxide) with efficiencies as higher as 90-95% and low energy demand, depending on the design optimization. In this work, a multi-step approach was applied to the ... En savoir plus

Modeling of Mixing-Sensitive Pharmaceutical Drug Substance Processes in Batch Reactors

F. Akpinar [1], B. Cohen [1], J. Tabora [1], A. Glace [1], K. Lauser [1], F. Lora Gonzalez [1], J. Albrecht [1],
[1] Bristol-Myers Squibb, New Brunswick, NJ, USA

Manufacturing of pharmaceutical drug substances involves chemical unit operations that are dependent on effective mixing, particularly reactions and crystallizations. Poor mixing can cause uneven distribution of chemical species in stirred tanks, leading to impurity formation and ... En savoir plus

Simulation of the Geometric Design Parameters’ Impact on the Performance of EHD Ion-Drag Micropump

M. Badran [1],
[1] Future University in Egypt, New Cairo, Egypt

A two-dimensional numerical simulation study has been performed to model an electrohydrodynamic (EHD) micropump. The emphasis of this study was on simulating the effect of the different geometric design parameters on the micropump pressure head and volume flow rate. The simulated design ... En savoir plus
