Elasto-Plastic FEM Models Explain the Emplacement of Shallow Magma Intrusions in Volcanic Complexes

A. Bistacchi[1]
[1]Università degli Studi di Milano Bicocca, Milano, Italy

We present numerical models and field data that aid understanding of volcano-tectonic processes related to the propagation of inclined sheets and dykes under a stress field resulting from the inflation of a shallow magma chamber. Structural field data from the classical Cuillins cone ... Read More

Post Harvest Cold Chain Optimization of Little Fruits

S. Marai[1], E. Ferrari[1], R. Civelli[1]
[1]DiSAA, University of Milan, Milan, Italy

This paper presents heat transfer 3-D models of a passive refrigeration system used to improve the shelf life and the quality of the perishable fruits. Passive refrigerator system uses the changing phase to keep temperature close to the melting temperature. A multi-step study was ... Read More

COMSOL Multiphysics Super Resolution Analysis of a Spherical Geodesic Waveguide Suitable for Manufacturing

[1]Cedint Universidad Politécnica de Madrid, Madrid, Spain

Recently it has been proved theoretically (Miñano et al, 2011) that the super-resolution up to ? /500 can be achieved using an ideal metallic Spherical Geodesic Waveguide (SGW). This SGW is as a theoretical design, in which the conductive walls are considered to be lossless conductors ... Read More

3D Simulations of an Injection Test Done Into an Unsaturated Porous and Fractured Limestone

A. Thoraval[1], Y. Guglielmi[2], F. Cappa[3]
[1]INERIS, Nancy, France
[2]CEREGE, Aix-en-Provence, France
[3]GEOAZUR, Valbonne, France

We have developed a numerical model to represent the effect of injection test in unsaturated porous and fractured rock mass. The test was conducted at the LSBB (Laboratoire Souterrain à Bas Bruit) site close to Rustrel, Vaucluse, France in the field of the French ANR project called “HPPP ... Read More

Detector and Calibration-source Models for the SAFARI Detector Test Facility

M. Audley[1], G. de Lange[1], C. Bracken[2]
[1]SRON Netherlands Institute for Space Research, Groningen, The Netherlands
[2]National University of Ireland, Maynooth, Ireland

SAFARI is a far-infrared imaging spectrometer for the Japanese satellite observatory SPICA. SAFARI covers the wavelength range 34—210 μm (1.4—8.8 THz) using Transition-Edge-Sensor (TES) bolometers. We have built a test facility to qualify and characterize the SAFARI focal plane units ... Read More

Influence of Thermal Conductivity and Plasma Pressure on Temperature Distribution and Acoustical Eigenfrequencies of High-Intensity Discharge Lamps

J. Schwieger[1], B. Baumann[1], M. Wolff[1], F. Manders[2], J. Suijker[2]
[1]Heinrich-Blasius-Institute of Physical Technologies, Hamburg University of Applied Sciences, Hamburg, Germany
[2]Philips Lighting, Turnhout, Belgium

High-intensity discharge (HID) lamps are energy-efficient light sources with excellent color qualities. A three-dimensional model of a low-wattage lamp, which includes plasma, electrodes, and burner walls, was developed in COMSOL Multiphysics®. Most parameters appearing in the coupled ... Read More

Numerical Simulation of Forced and Static Smoldering Combustion

S. Singer[1], W. H. Green[1]
[1]Massachusetts Institute of Technology, Cambridge, MA, USA

Transient, two-dimensional (axisymmetric) simulations of a cigarette subject to realistic static and forward smoldering cycles were performed. The computational domain consists of a porous packed bed of tobacco and a filter surrounded by a thin, porous paper and a region of surrounding ... Read More

Finite-Element Analysis of High Frequency Electromagnetic Fields

Masanori HASHIGUCHI et al.[1]

[1]Keisoku Engineering System Co., Ltd., Chiyoda City, Tokyo, Japan

Using COMSOL Multiphysics, numerical solution of electromagnetic field of microstrip open stub is obtained in frequency domain of 0.1GHz - 60GHz by using the COMSOL RF Module and the computed S11 is compared to experiment. It was found that the S11 predicted here is in good agreement ... Read More

Simulation of MEMS Based Pressure Sensor for Diagnosing Sleep Disorders

J. Vijitha[1], S. S. Priya[1], K. C. Devi[1]
[1]PSG College of Technology, Coimbatore, Tamil Nadu, India

Sleep apnea is a type of sleep disorder characterized by pauses in breathing or instances of shallow or infrequent breathing during sleep. There is a need to diagnose sleep apnea since it leads to fluctuations in the oxygen level that in turn affect the heart rate and blood pressure. In ... Read More

Design, Fabrication and Simulation of Microchannel Network for MEMS

V. Jain[1], A. K. Sharma[2], P. Kumar[2]
[1]Thapar University, Patiala, Punjab, India
[2]Indian Institute of Technology Roorkee, Roorkee, Uttar Pradesh, India

The greatest challenge being faced for realization of Micro-Electro Mechanical System (MEMS) technology is the lack of a simple, quick and reliable method for the fabrication of 3-D microchannel in the range of micrometers. A novel fabrication technique which opens possibilities for the ... Read More
