[2]CPS, Nazarbayev University, Astana, Kazakhstan
[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, ... Read More

Finite Element Analysis of Induced Electroosmotic Flow in Brain Tissue and Application to ex vivo Determination of Enzyme Activity

Y. Ou[1], A. Rupert[1], M. Sandberg[2], S. Weber[1]
[1]University of Pittsburgh, Pittsburgh, PA, USA
[2]University of Gothenburg, Gothenburg, Sweden

Ectopeptidases are commonly accepted to be a means of clearing active peptides. However, studies have shown that they can also regulate peptide activity. We have developed a technique of electrokinetic push-pull perfusion (Ek-PPP, Figure 1) to examine this largely unexplored mechanism of ... Read More

Prediction of Transformer Load Noise

M. Kavasoglu[1], R. Haettel[1], and C.H. Ploetner[2]
[1]ABB Corporate Research, Västerås, Sweden
[2]ABB Transformers, Varennes, Canada

Transformers, as any other industrial products, have to comply with various requirements on noise levels. Three main sources of noise can be identified in transformers: no-load noise or core noise generated by magnetostriction in the core steel laminations, load noise produced by ... Read More

Modeling of Transport Phenomena in Metal Foaming

B. Chinè[1], M. Monno[2]
[1]Laboratorio MUSP Piacenza, Italy; ITCR, Esc. Ciencia e Ing. Materiales, Cartago, Costa Rica
[2]Laboratorio MUSP, Piacenza, Italy; Politecnico di Milano, Dip. Meccanica, Milano, Italy

Metal foams are interesting materials with many potential applications in engineering. Foamed metals or alloys include gas voids in the material structure with the real possibility to modify ad hoc their physical properties. Following our previous efforts aimed to simulate and study the ... Read More

Hydrogen Vehicle Leak Modelling in Indoor Ventilated Environments

A. Hallgarth[1], A. Zayer[1], A. Gatward[2], and J. Davies[2]
[1]Hazard Research & Risk Consultants Ltd, Aberystwyth, Wales, United Kingdom
[2]Independent Consultants, United Kingdom

This paper presents and discusses HazRes’ research and results associated with the simulation and modelling of hydrogen release and dispersion events in indoor enclosed environments, using COMSOL Multiphysics. HazRes has developed a gas dispersion model in COMSOL, which takes into ... Read More

Computationally Assisted Design and Experimental Validation of a Novel ‘Flow-Focussed’ Microfluidics Chip for Generating Monodisperse Microbubbles

M. Conneely[1], V. Hegde[2], H. Rolfsnes[1], A. Mason[2], D. McLean[1], C. Main[1], F.J.D. Smith[2], W.H.I. McLean[2], P.A. Campbell[1]
[1]Carnegie Physics Laboratory, University of Dundee, Dundee, Scotland, United Kingdom
[2]Division of Molecular Medicine, University of Dundee, Dundee, Scotland, United Kingdom

Whilst initially developed as a diagnostic aid to improve echogenicity in ultrasound imaging, gas-filled lipid microbubbles are now emerging as a next generation \'theranostic\' tool in the medical arena. Here, their therapeutic potential has now been realized through their unique ... Read More

Active Infrared Technique for Landmine Detection: Numerical and Experimental Results

P. Fallavollita[1,2], S. Esposito[1,2], and M. Balsi[1,2]
[1]Dipartimento di Ingegneria dell’Informazione, Elettronica e Telecomunicazioni, “La Sapienza” University, Rome, Italy
[2]Humanitarian Demining Laboratory, Cisterna di Latina, Italy

Landmines are an open problem in many countries of the world. They cause injuriesand death and no technique proposed to date guarantees fast and 100% reliable detection alone. To this purpose, at the Humanitarian Demining Laboratory of “La Sapienza” University of Rome, several solutions ... Read More

2D Axial-Symmetric Model For Fluid Flow And Heat Transfer In The Melting And Resolidification Of A Vertical Cylinder

S. Morville[1], M. Carin[1], M. Muller[2], M. Gharbi[2], P. Peyre[2], D. Carron[1], P. Le Masson[1], and R. Fabro[2]
[1]Laboratoire LIMATB, Université de Bretagne Sud, Lorient , France
[2]Laboratoire PIMM, Arts et Métiers ParisTech, Paris, France

Laser direct deposition is a process, different from molding or machining, which allows the producing of fully densified and operational components. This technique involves injecting metal powder through a coaxial nozzle into a melt pool obtained by a moving laser beam. The final object ... Read More
