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 ... Read More

Modeling of Transport Phenomena in Laser Welding of Steels

[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 ... Read More

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 ... Read More

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 ... Read More

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 ... Read More

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 ... Read More

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 ... Read More

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 ... Read More

The Acoustic Behavior of a Loudspeaker Mounted on Different Types of BIW (Body-in-white) Frames

Niranjan Ambati [1], F. Malbos [2], Michal Bogdanski [3], Michael Strauss [3],
[1] Harman International Private Limited, Bangalore, Karnataka, India
[2] Harman France SNC, France
[3] Harman Becker Automotive Systems, Germany

For automotive applications, simulations are used to optimize the position and orientation of a subwoofer (loudspeaker) in a very constrained space to get the best acoustic performances. One solution is to use particular part of the BIW volume as the subwoofer enclosure. The acoustical ... Read More
