[1]1. Continuum Blue Ltd., Tredomen Innovation & Technology Park, Tredomen, Ystrad Mynach, United Kingdom
[2]BAE Systems, Advanced Technology Centre, Bristol, United Kingdom

A time-dependent COMSOL Multiphysics model of an additive manufacture process, which uses powder consolidation by laser heating was developed, providing a platform to better understanding the manufacture process & provide a tool to reduce resulting distortion & optimization of an ... Read More

Prototype Probe Development for Liquid Injection Shutdown System Tube Gap Detection by Remote Field Pulsed Eddy Current Technique

T. V. Shyam[1], B. S. V. G. Sharma[1], J. N. Kayal[1]
[1]Bhabha Atomic Research Centre, Trombay, Mumbai, India

Pressurised Heavy Water Reactors (PHWR) play a prominent role in contributing power for the Nuclear Energy Programme in India. In 540MWe type PHWR reactors, there are horizontally placed Liquid Injection Shutdown System (LISS) tubes for injecting poison into the moderator to clamp down ... Read More

Development and Optimization of a Microfluidic Device for Magnetic Field Induced Cell Separation

L. Helmich[1], A. Hütten[1]
[1]Bielefeld University, Bielefeld, Germany

Besides conventional laboratory analysis methods, so called micro-total-analysis devices (µTAS) have gained great interest during the last decades. In this work we demonstrate a mechanism for the separation and selection of medical samples that can be applied within these µTAS devices. ... Read More

Feed-forward/Feed-backward Mechanical Amplification in the Mouse Cochlea

J. Soons[1,2], C. Steele[2], S. Puria[2]
[1]Lab of Biomedical physics, University of Antwerp, Antwerp, Belgium
[2]Department of Mechanical Engineering, Stanford University, Stanford, USA

Sound vibrations are collected from the external environment by the eardrum and are guided to the basilar membrane in the cochlea. Pressure differences in the two scalae of the cochlea result in a traveling wave on the basilar membrane. The tiny displacements are detected by the ... Read More

Modeling Plant Morphodynamics in Predefined COMSOL Multiphysics® Interface

S. Nikolaev[1], A. Trubuil[2]
[1]Institute of cytology and genetics SB RAS, Novosibirsk, Russia
[2]Institut National de la Recherche Agronomique, Jouy-en-Josas, France

We used a predefined COMSOL Multiphysics® interface to imitate biological growth and shape change (morphodynamics). We found a set of parameters that supply observed morphodynamics for an Arabidopsis embryo during its transition from globular to heart stage. Read More

Modeling Charge/Discharge Heat Generation of Li-ion Cells and Experimental Verification of Temperature Distribution

Tatsuya YAMAUE[1]
[1] Kobelco Research Institute, Inc., Kobe, Hyogo, Japan

Modeling the heat generation and the heat transfer of the electrode of lithium-ion battery are introduced. There are several models, such as an homogeneous heating model and a model considering the current and reaction distribution of electrode. Generally, electrodes have large area and ... Read More
