An Approach to Modeling Vacuum Desorption new

C. F. Gomez[1], R. Schunk[1], R. F. Coker[1], J. Knox[1]
[1]NASA Marshall Space Flight Center, Huntsville, AL, USA

The objective of this simulation effort is to develop a mathematical model of vacuum desorption on a POC (Proof of Concept) canister loaded with Zeolite 13X/5A . This canister contains a pelletized adsorption bed which is used to adsorb H2O and CO2. Once this bed is fully saturated with ... Read More

Thermal Clothing Engineering Using a COMSOL® Simulation App

B. Van Der Smissen [1], S. Vasile [2],
[1] University College Ghent, Faculty of Science and Nature, Mechatronics, Ghent, Belgium
[2] University College Ghent, Science and Nature, Fashion, Textile and Wood Technology, Ghent, Belgium

In this paper the development of a COMSOL® app for the engineering design of thermal quality clothing has been started. The software architecture is developed for different design strategies. Specific design requirements lead to different simulation models for the clothing wearing system ... Read More

Cascades of Secondary Particles in High Voltage Accelerators

[3]Centro Ric. E. Fermi, Roma, Italy

A very simplified system for high voltage test is studied, considering reason for voltage holding failures which are not covered by conventional and local design criteria. A first understanding of the problem is obtained by solving the electrostatic potential in a 2D axis symmetric ... Read More

Simulation Studies on Stress Generation and Volume Expansion due to Electrochemical Lithium Insertion in a Silicon Nanowire

G. Sikha, and J. Gordon
Applied Materials, Inc.
Santa Clara, CA

Silicon electrodes are presently being pursued as the potential negative electrode for lithium-ion batteries owing to its high gravimetric (mAh/g) and volumetric capacity (mAh/L) compared to the existing state of the art graphite electrode. Recent experimental studies have demonstrated ... Read More

Numerical Evidence of Unrest-Related Electromagnetic Effects in the Campi Flegrei Caldera, Italy

G. Perillo [1], G. De Natale [2], M. G. Di Giuseppe [2], A. Troiano [2], C. Troise [2],
[1] University of Naples Parthenope, Naples, Italy
[2] INGV – Osservatorio Vesuviano, Naples, Italy

Electric, magnetic and electromagnetic (em) methods are widely used to monitor active volcanoes. A review of such applications is presented in Johnston (cit). Em signals were recorded in correspondence of numerous volcanic eruptions, for example in the case of the Mt. Unzen in Giapppone, ... Read More

Multiphysics Modelling of Food Dehydration during RF Exposure

R. Renshaw[1]
[1]e2v Ltd., Essex, United Kingdom

There is a requirement for an RF (Radiofrequency) industrial dryer that will be capable of dehydrating foodstuff to the correct level after the product has been fried. RF drying should actively target moisture, due to waters high dielectric properties. An industrial dryer can be ... Read More

RF Hot-Zone Location within Rectangular Confined Spaces

R. Rodriguez[1]
[1]University of the West Indies, St. Augustine, Trinidad and Tobago

RF propagation modelling in (30 – 1000 MHz) SAR region for predicting the location and intensities of constructive interference patterns within rectangular confined spaces using waveguide theory and ray tracing techniques. Read More

Modelling of Heat and Moisture Transport in a Corrugated Board Stack new

M. Xynou[1]
[1]KTH Royal Institute of Technology, Stockholm, Sweden

Corrugated board is produced on a machine where the corrugated medium is glued between two flat paper surfaces, the liners. The board is cut into sheets and stored in a stack until suitable moisture content has been reached. The sheets are then cut and creased into blanks for the ... Read More

Strong Localization and Rapid Time Scales of Superheating in Solid-State Nanopores new

E. Levine[1], G. Nagashima[1], D. Hoogerheide[1], M. Burns[2], J. Golovchenko[1]
[1]Harvard University, Cambridge, MA, USA
[2]Rowland Institute at Harvard University, Cambridge, MA, USA

Extreme localized superheating and homogeneous vapor bubble nucleation have recently been demonstrated in a single nanopore in thin, solid state membranes [1]. Aqueous electrolytic solution present within the pore is superheated to well above its boiling point by Joule heating from ionic ... Read More

The Effect of Multi-Materials for Microwave Heating Uniformity

Huacheng Zhu [1], Quansheng Wang [1], Youqi Deng [1], Qian Meng [1],
[1] Sichuan University, Chengdu, China

To overcome the uneven heating during the process of microwave heating of food inside microwave oven, a geometrical model based on domestic microwave oven with a cylindrical container composed of multi-materials(with two different kinds of materials, one half is glass and the other half ...
