[3]Institute of Batteries, Astana, Kazakhstan

A design for the thermal management of the media used for packing Li-ion batteries used in hybrid and electric vehicles has been developed. The design satisfies all thermal and physical issues relating to the battery packs used in vehicles such as operating temperature range and volume, ... 詳細を見る

Modeling of Anisotropic Laminated Magnetic Cores Using Homogenization Approaches

H. Neubert[1], J. Ziske[1], R. Disselnkötter[2]
[1]Technische Universität Dresden, Institute of Electromechanical and Electronic Design, Dresden, Germany
[2]ABB Corporate Research Center, Ladenburg, Germany

3D-modeling of magnetic components with FEM is challenging due to the involved nonlinearities and coupling effects between different physical domains. A specific issue is the consideration of lamination due to the high resulting element count for thin layers. Therefore, several ... 詳細を見る

Role of the Diffusion Current in Nonequilibrium Modeling of Welding Arcs

M. Baeva[1]
[1]INP Greifswald e.V., Greifswald, Germany

2D self-consistent nonequilibrium model of a free-burning arc in argon has been developed. The model is based on the COMSOL Multiphysics® platform and describes in a self-consistent manner the fluid dynamics, the heat transfer, the magneto-electrodynamics, and species conservation. The ... 詳細を見る

Birefringence Induced in Optical Rib Waveguides by Thermal and Mechanical Stresses

[1]Department of Applied Geology, GZG, Georg-August- University of Göttingen, Göttingen, Germany
[2]Hölscher Wasserbau GmbH, Haren, Germany

Vertical circulation wells (VCWs) are well system consisting dual-screened sections allowing synchronous extraction and injection of groundwater in a single borehole. Vertical circulation flow or dipole flow is induced. This type of well has been widely used for in-situ remidiation, ... 詳細を見る

Enhanced Surface Plasmon Polariton Propagation Induced by Active Dielectrics

M. Mattheakis[1], C. Athanasopoulos[1], G. P. Tsironis[1]
[1]University of Crete, Heraklion, Greece

We present numerical simulations for the propagation of surface plasmon polaritons in a dielectric-metal-dielectric waveguide using COMSOL Multiphysics® software. We show that the use of an active dielectric with gain that compensates metal absorption losses enhances substantially ... 詳細を見る

Numerical Optimization of Heating for High-Speed Rotating Cup by Means of Multiphysics Modeling and its Experimental Verification

[1]University of Bayreuth, Chair of Materials Processing, Bayreuth, Germany

The physics of rotating cups and disks is an important research subject in many areas of engineering. The rotating cup/disk has been employed in many industrial applications such as spin-coating of phosphor on television screens or photoresist films on silicon wafer, concentrating ... 詳細を見る

Heat Propagation Improvement in YBCO-Coated Conductors for Superconducting Fault Current Limiters

D. M. Djokic[1], L. Antognazza[1], M. Abplanalp[2], M. Decroux[1]
[1]DPMC, University of Geneva, Geneva, Switzerland
[2]ABB Corporate Research Centre, Dättwil, Switzerland

YBCO Coated Conductors (CCs), used for applications in Resistive Superconducting Fault Current Limiters (RSFCLs), are known to have insufficiently high Normal Zone Propagation Velocity (NZPV) during quench events. The improvement can be made by enhancing the thermal conductivity of YBCO ... 詳細を見る

Long Range Ultrasonic Guided Waves for Pipelines Inspection

Á. Angulo[1], Dr. S. Soua[1]
[1]TWI Ltd, Cambridge, UK

The evaluation of defect size and nature are two most controversial topics in ultrasonic flaw detection. The operation consists of an application of ultrasonic waves to pipes in order to detect metal loss and other defects in the pipe wall due to corrosion and other degradation ... 詳細を見る
