Prediction of Transformer Core Noise

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

Today, low noise is a mandatory feature for power transformers to comply with customer specifications and environmental regulations. Therefore, it is crucial to develop sound prediction tools with sufficient accuracy to avoid overkill margins in design and costly modifications after ... Read More

Prediction of Noise Generated by Electromagnetic Forces in Induction Motors

M. K. Nguyen[1], R. Haettel[2], A. Daneryd[2]
[1]KTH, Stockholm, Sweden
[2]ABB Corporate Research,Västerås, Sweden

Induction motors, as any other industrial products, have to comply with various requirements on noise levels. Therefore, it is essential to use an appropriate prediction tool to verify and optimize the design of an induction motor with respect to the acoustic performances. The paper ... Read More

Stresses Due to Intercalation of Non-Spherical Lithium Storage Particles

R. Purkayastha[1], R. McMeeking[2]
[1]Cambridge University, Cambridge, UK
[2]University of California, Santa Barbara, CA, USA

Due to computational considerations most models of lithium storage particles in batteries incorporate spherical particles. However most storage particles used in battery electrodes tend to be irregular in shape with sharp edges and extended aspect ratios. The change of the relative ... Read More

Numerical Simulation of the Lithium-Ion Battery Cell Discharge Characteristics

Z. Umar[1], D. Ledwoch[1], L. Komsiyska[1], S. Vasić[[1]
[1]EWE-Forschungszentrum für Energietechnologie e. V, Oldenburg, Germany

In general battery cells are charged/discharged using constant current or constant power expressed as C-Rates and P-Rates respectively. We are developing a single cell-level Li-Ion battery model in order to simulate the performance and the physicochemical phenomena under power ... Read More

Investigating the Performance of Mechanically Ventilated Double-Skin Facades with Solar Control Devices in the Main Cavity

C. G. Galante[1]
[1]Newtecnic Ltd, London, England, UK

The use of ventilated facades may reduce the cooling and heating energy demands of the building. Double-skin facades (DSFs) belong to the wider group of ventilated facades and currently represent one of the most interesting and studied facade systems. The purpose of this study is to ... Read More

Multiphysics Modeling of Electrode-Driven Renal Denervation for Hypertension Treatment

M. Miliani[1], F. Piccagli[1], C. Silvestro[1]
[1]Medtronic Invatec S.p.A., Roncadelle, Italy

Introduction: Chronic arterial hypertension (HTN) is a pathological condition characterized by prolonged high level of arterial blood pressure causing major damages to several human body apparata. Renal sympathetic denervation (RDN) has been found to effectively reduce systemic blood ... Read More

Numerical Simulation of Chamber Design for Pulsed Electric Fields Processing of Wet Olive Pomace

N. Varga[1], I. Perales[2], A. Portugal[2]
[1]ATEKNEA Solutions Hungary, Budapest, Hungary
[2]ATEKNEA Solutions Catalonia, Barcelona, Spain

The application of pulsed electric fields (PEF) is well known in the food industry as an advanced technology for mass transfer improvement. A new potential adaptation area of PEF could be extracting a valuable antioxidant called polyphenol from wet olive pomace (WOP) which is a by ... Read More

Simulation and Performance of Pulsed Pipe Flow Mixing in Non-Newtonian Liquid Dispersion Media

T. Koiranen[1], J. Tamminen[1], A. Häkkinen[1]
[1]LUT Chemtech, Lappeenranta University of Technology, Lappeenranta, Finland

A non-newtonian oil dispersion in a pulsed flow pipe system was mixed in a circulation loop pipe with custom-made static mixers. The rotor-pump was used in a non-pulsed flow circulation, and diaphragm pump for pulsed flow circulation. Modeling was done using COMSOL Multiphysics® 4.3b. ... Read More

Use of COMSOL Multiphysics® for IAQ Monitoring in Cleanrooms

G. Petrone[1], C. Balocco[2]
[1]BE CAE & Test, Catania, Italy
[2]Department of Industrial Engineering, University of Firenze, Firenze, Italy

High levels of Indoor Air Quality (IAQ) in Operating Theatres (OT) is an important issue in order to contribute in prevention of Surgical Site Infections (SSI). Despite of specific plant layouts are applied for OT ventilation (e.g. unidirectional flow), the effective use conditions can ... Read More
