Parametric Study of Heavy Oil Recovery by Electromagnetic Heating on a Horizontal Well

M. Liu[1], G. Zhao[1]
[1]University of Regina, Regina, SK, Canada

This study presents a oil-gas two-phase linear flow EMH model using COMSOL Multiphysics simulator. Special attention is focused on reservoirs with characteristics for which steam injection is not attractive or feasible such as low permeability, thin-zone, and extra-heavy oil reservoirs. ...

Modeling of Chloride Transport in Cracked Concrete: a 3-D Image–Based Microstructure Simulation

Y. Lu[1], E. Garboczi[1], D. Bentz[1]
[1]National Institute of Standards and Technology, Gaithersburg, MD, USA

The prediction of concrete materials service life is not easy, because the complex heterogeneous microstructure and the random nature of concrete materials. Study the presence of cracks in concrete and their effect on coupled reaction and transport are of great interest in civil ... En savoir plus

Geometric Optimization of Micromixers

M. Jain[1], A. Rao[1], K. Nandakumar[1]
[1]Cain Department of Chemical Engineering, Louisiana State University, Baton Rouge, LA, USA

The performance of a homogeneous T-mixer can be enhanced significantly by the stimulation of secondary/ transverse flows in the microchannel. Various mixing mechanisms are reported for enhancing micromixing performance such as grooves at the channel bottom, heterogeneous charge patterns ... En savoir plus

Modeling Proton Transport in Hydrophobic Polymeric Electrolytes

M. Andrews[1]
[1]Caribbean Industrial Research Institute, Calibration Laboratory, University of the West Indies, St. Augustine, Trinidad and Tobago

The Polymer Electrolyte Membrane fuel cell is one of the most promising green technologies for addressing portable, as well as transportation power needs. However, the science behind the fuel cell, in many regards, is still an enigma, and even more so, with the vast numbers of novel ... En savoir plus

Modeling of the Reduction Stage during the Continuous Refining of Copper in a Packed Bed Reactor

F. Mansilla[1], L. Voisin [2]
[1]Advanced Mining Technology Center, Chile University, Santiago, Chile
[2]Department of Mining Engineering, Advanced Mining Technology Center, Chile University, Santiago, Chile

Throughout history, the copper pyrometallurgical processes have been carried out mostly in discontinuous or batch systems. In recent decades new continuous technologies have been developed but focused only on Smelting and Converting stages leaving aside the Refining one. In 2002 a novel ... En savoir plus

Experimental Validation of Model of Electro-Chemical-Mechanical Planarization (ECMP) of Copper

J. Ebert[1], S. Ghosal[1], A. Emami-Naeini[1]
[1]SC Solutions, Sunnyvale, CA, USA

This paper describes the development of a COMSOL model of Electro-Chemical-Mechanical Planarization (ECMP) that was validated with experimental data. ECMP is used for processing of semiconductor wafers. We developed a 2D model of flow of phosphoric acid solution (the electrolyte) between ... En savoir plus

Upscaling of Heterogeneous Rock Properties via a Multiscale Image to Simulation Approach

S. Zhang[1], M. Pal[2], P. Barthelemy[1], M. Lei[1]
[1]Visualization Sciences Group, Burlington, MA, USA
[2]Shell International Exploration and Production, Rijswijk, The Netherlands

The mass and recoverability of oil and gas in unconventional reservoirs strongly depend on the understanding the petrophysical properties of the rocks at a large range of scales. Three-dimensional imaging is capable of unveiling the detailed microstructures within the rocks down to the ... En savoir plus

C. Hurt[1], P. Angelo[2], R. Pevey[1]
[1]Department of Nuclear Engineering, University of Tennessee, Knoxville, TN, USA
[2]Y-12 National Security Complex, Safety Analysis Engineering, Oak Ridge, TN, USA

Simulation of criticality accident transients offers the ability to confirm understanding of critical configurations, bound accident scenarios and aid comprehensive emergency planning. Computational ability to recreate excursion power histories in fissile solution is sought due to the ... En savoir plus

Multiphase Transport with Large Deformations Undergoing Rubbery-Glassy Phase Transition: Applications to Drying

T. Gulati[1], A. Datta[1]
[1]Department of Biological and Environmental Engineering, Cornell University, Ithaca, NY, USA

Drying of biomaterials such as foodstuffs involves mass, momentum and energy transport along with large shrinkage of the porous material, which have significant effects on their final quality. Foodstuffs exhibit non-linearity when undergoing large deformations that affect the transport ... En savoir plus

Application of COMSOL Multiphysics in the Simulation of Magnesium Refining and Production

X. Guan[1], E. Gratz[1], U. Pal[1]
[1]Division of Materials Science and Engineering, Boston University, Brookline, MA, USA

Computational fluid dynamics (CFD) modeling is a useful tool to gain an insight into various high temperature metallurgical processes such as the magnesium refining and the magnesium solid oxide membrane (SOM) electrolysis. In both processes, argon gas was used to stir the molten salt ... En savoir plus
