Modeling Cavity Growth in Underground Coal Gasification

A. Sarraf Shirazi, J. Mmbaga, and R. Gupta
University of Alberta
Edmonton, AB
Canada

Underground coal gasification (UCG) has received renewed interest due to its potential for utilization of the vast amounts of coals available in deep underground seams and the current drive towards clean coal utilization. UCG process involves the reaction between air/steam and coal in ... Read More

Coupled Gas Flow and Thermal and Reactive Transport in Porous Media for Simulating Waste Stabilization Phenomena in Semi-Aerobic Landfill

H. Ishimori, K. Endo, T. Ishigaki, H. Sakanakura, and M. Yamada
National Institute for Environmental Studies
Tsukuba, Ibaraki
Japan

Semi-aerobic landfill has interesting structure that passively provides the atmospheric oxygen into landfilled waste due to the heat convection generated by the decomposition of landfilled waste. There are limited studies on the mechanisms of the oxygen transport. This paper presents the ... Read More

Improving Fuel Usage in Microchannel Based Fuel Cells

P. Fodor, and J. D'Alessandro
Dept. of Physics
Cleveland State University
Cleveland, OH

In this work a miniaturized fuel cell design based on microchannels, into which the liquid fuel and oxidizer streams are fed through T shaped connectors, is optimized for improved fuel usage. This particular design exploits the laminar nature of the fluid flow at small Reynolds numbers ... Read More

Multi-Domain Analysis of Silicon Structures for MEMS Based-Sensors

N. Bhalla[1], S. Li[2], and D. Chung[1]
[1]Chung Yuan Christian University, Chungli,Taiwan
[2]National Tsing Hua University, Hsinchu, Taiwan

Investigation in this paper aims at performing Mechanical Stress Strain analysis, Thermal, Piezoresistive and Piezoeletric analysis of Silicon Structures using COMSOL. The simulation results have been cross checked by mathematical calculation. Read More

Non-Equilibrium Quantum Well Populations and Optical Characteristics of III-Nitride Lasers and Light-Emitting Diodes

M. Kisin, and H. El-Ghoroury
Ostendo Technologies, Inc.
Carlsbad, CA

COMSOL-based Ostendo’s Optoelectronic Device Modeling Software (ODMS) has been updated to include effects of non-equilibrium QW populations in semiconductor light-emitting and laser diodes. III-nitride light emitters with different levels of polarity have been compared as an ... Read More

Smoothing the Path to Simulation-Led Device Design

B. Pryor, and R. Pryor
Pryor Knowledge Systems
Bloomfield Hills, MI

Using modeling software such as COMSOL Multiphysics during the design phase, an approach called “simulation-led design”, allows ideas to be both inspired and validated by the use of simulations. Then, using simulations after the product is designed can shorten the prototype-testing ... Read More

Deriving Correction Factors for a Primary Standard for Radiation Dosimetry

R. Tosh, and H. Chen-Mayer
NIST
Gaithersburg, MD

Accurate metrology of radiotherapeutic absorbed dose to water requires assessing the radiation induced temperature change. The most direct method for doing this is water calorimetry, for which the established technique involves the use of slender thermistor probes that are sealed within ... Read More

Simulation of Field Enhancement in Anisotropic Transition Metamaterials using COMSOL

A. Pandey, and N. Litchinitser
The State University of New York at Buffalo
Buffalo, NY

Transition metamaterials constitute a new class of engineered materials which have material properties tailored in such a manner that the refractive index gradually changes from positive to negative. An important question is what happens at the interface of a positive and negative index ... Read More

Analysis of Thermoelectric Phenomena

J. Crompton, S. Yushanov, L. Gritter, and K. Koppenhoefer
AltaSim Technologies, LLC.
Columbus, OH

Thermoelectric phenomena provide the direct conversion of heat into electricity or electricity into heat, the phenomena is described by three related mechanisms: the Seebeck, Peltier and Thomson effects. Thermoelectric devices have found many applications ranging from temperature ... Read More

Analysis of Microwave Radiation for Heating

J. Crompton, S. Yushanov, L. Gritter, and K. Koppenhoefer
AltaSim Technologies, LLC.
Columbus, OH

Microwave heating is an important process for many commercial, industrial and household applications. In microwave heating applications, the energy is introduced directly into the volume of the material. As a consequence the quality of the process is highly dependent on the uniformity of ... Read More
