Deep Desulfurization of Diesel Using a Single-Phase Micro-Reactor

G. Jovonavic[1], J. Jones[1], and A. Yokochi[1]
[1]School of Chemical, Biological and Environmental Engineering, Oregon State University, Corvallis, Oregon, USA

This paper describes the benefits of computational fluid dynamics in the development of a microreactor used in the desulfurization of aromatic compounds. It is crucial to verify diffusion and extinction coefficients to ensure accurate simulation results prior to experiments. COMSOL ... Read More

Design Simulations of a General Purpose Research Micro Reactor for Methane Conversion to Syngas.

C. Bouchot[1], and M.A. Valenzuela[1]
[1]Instituto Politécnico Nacional-ESIQIE, México D.F, México

A general purpose stainless steel micro reactor setup for methane conversion is being designed for research purposes. We intend to design and build a modular device that would be able to manage different types of reactions depending on the installed modules. The device should be able to ... Read More

Designing B-field Coils from the Inside-Out

C.B. Crawford[1], Y. Shin[1], and G. Porter[1]
[1]Department of Physics and Astronomy, University of Kentucky, Lexington, Kentucky, USA

Traditionally the design cycle for magnetic fields involves guessing at a reasonable conductor / magnetic material configuration, using FEA software to calculate the resulting field, modifying the configuration, and iterating to produce the desired field. Our method involved solving the ... Read More

Effect of S-p Relation Model on DNAPL Migration Simulation Result

H. Ishimori[1], and K. Endo[1]
[1]National Institute for Environmental Studies, Tsukuba, Ibaraki, Japan

To consider effective counter measures against ground water contaminated with dense non-aqueous phase liquids (DNAPLs) such as chlorinated solvents, it is first important to understand the mechanism of their migration in heterogeneous aquifer. In addition, numerical analysis models to ... Read More

Electro Magnetic Wave Simulation in Fusion Plasmas

O. Meneghini[1], and S. Shiraiwa[1]
[1]Plasma Science and Fusion Center, Massachusetts Institute of Technology, Massachusetts, USA

Fusion is a form of nuclear energy which has impressive advantages from the point of view of fuel reserves, environmental impact and safety. If successful, fusion energy would ensure a safe, resource conserving, environmentally friendly power supply for future generations. In a world ... Read More

Error Analysis in Estimating Temperature-Dependent Thermal Diffusivity and Kinetic Parameters using Heat Penetration Data

K.D. Dolan[1,2], A.R. Sommerlot[1], and D.K. Mishra[1]
[1]Department of Biosystems and Agricultural Engineering, Michigan State University, East Lansing, Michigan, USA
[2]Department of Food Science and Human Nutrition, Michigan State University, East Lansing, Michigan, USA

Growing consumer demand for nutraceuticals has stimulated interest by food companies to increase levels of these health-promoting compounds. Thermal processing of canned foods in a retort produces a unique problem: some of the nutraceuticals are highly sensitive to temperature, and ... Read More

Two-Dimensional COMSOL Simulation of Heavy-Oil Recovery by Electromagnetic Heating

M. Carrizales[1], and L.W. Lake[1]

[1]The University of Texas at Austin, University Station, Austin, Texas, USA

Introducing heat to the formation has proven to be an effective way of lowering the oil viscosity of heavy oils by raising the temperature in the formation. The application of electrical energy has gained more interest during the last decade because it offers fewer restrictions for its ... Read More

Experimental Observation and Numerical Prediction of Induction Heating in a Graphite Test Article

T.A. Jankowski[1], D.P. Johnson[1], J.D. Jurney[1], J.E. Freer[1], L.M. Dougherty[1], and S.A. Stout[1]

[1]Los Alamos National Laboratory, Los Alamos, New Mexico, USA

The induction heating coils used in the plutonium casting furnaces at the Los Alamos National Laboratory are studied here. A cylindrical graphite test article has been built, instrumented with thermocouples, and heated in the induction coil that is normally used to preheat the molds ... Read More

Experimentally Matched Finite Element Modeling of Thermally Actuated SOI MEMS Micro-Grippers Using COMSOL Multiphysics

M. Guvench[1], and J. Crosby[1]
[1]University of Southern Maine, Gorham, Maine, USA

In “Micro-Electro-Mechanical-Systems” shortly known as MEMS, one of the most important and effective principle of creating transduction of electrical power to displacement force is thermal expansion. A slim beam of MEMS material, typically Silicon, is heated by the application of ... Read More

Finite element analysis approach for optimization of enzyme activity for enzymatic bio-fuel cell

C. Wang[1], Y. Song[1], Y. Parikh[1], and J.H. Yang[1]
[1]Department of Mechanical & Materials Science Engineering, Florida International University, Miami, Florida, USA

Enzymatic biofuel cells (EBFCs) are miniature implantable power sources, which use enzymes as catalysts to perform redox reaction with biological fuels such as glucose. In this study, we focused on a three dimensional EBFC chip with highly dense micro-electrode arrays, fabricated by ... Read More
