Numerical Study of Flux Models for CO2 - Enhanced Natural Gas Recovery and Potential CO2 Storage in Shale Gas Reservoirs

N. Prajapati[1], P. L. Mills[1]
[1]Department of Chemical & Natural Gas Engineering, Texas A&M University, Kingsville, TX, USA

This work encompasses different physics involved in fluid flow in shale gas reservoir. Non-linear equations for fluid flow are solved with COMSOL Multiphysics® PDE module. It focuses on comparing the performance of various species transport flux models by accounting for inter-molecular ... Read More

The Birefringence Change of Optical Fiber Polarizer with Fe-C Film in Corrosive Solution

胡文彬 [1], 丁立康 [1], 朱诚 [1], 袁银权 [1],
[1] 武汉理工大学光纤传感国家工程实验室

The detection of early corrosion is a key issue to mitigate the damage induced by metal corrosion. The optical fiber corrosion sensor based on a side-polished polarizer is realized recently. The polarizer is fabricated by sputtering a Fe film on a side-polished single mode fiber. The new ... Read More

Elastoplastic Modeling and Experimental Verification of Solder-Substrate Interaction

C. Karl[1], C. Slater[1], M. Strangwood[1], K. Tank[2], S. O'Connor[2]
[1]University of Birmingham, Birmingham, UK
[2]Strip Tinning Ltd, Birmingham, UK

Solders are typically used to join similar or dissimilar metals, referred to as substrates. In some cases solders are also used to join completely different classes of materials. For example, a joint between copper busbar and silicon solar cell represents a set of dissimilar ... Read More

COMSOL Multiphysics® Software Simulation of a Dual-axis MEMS Accelerometer with T-Shaped Beams

C. Zheng [1], X. Xiong [1], J. Hu [2]
[1] Department of Electrical and Computer Engineering, University of Bridgeport, Bridgeport, CT, USA
[2] Department of Mechanical Engineering, University of Bridgeport, Bridgeport, CT, USA

Introduction: Inertial navigation requires acceleration measurement along all three degree-of-freedoms. Most accelerometers are designed to measure acceleration along a single sensitive direction. For complete inertial sensing, a move effective accelerometer which can sense ... Read More

Topology Optimization of Lithium-Ion Battery Electrode Microstructure Morphology for Reduction of Damage Accumulation and Longevity of Battery Life

P. Clarke[1], R. Abedi[1]
[1]University of Tennessee Space Institute, Tullahoma, TN, USA

The ubiquitous commercial use of Lithium-Ion batteries (LIBs) has increased interest in their implementation into efficient energy storage systems for clean and renewable power sources and the electrical transportation industry. Unfortunately, LIBs are not yet technological mature to ... Read More

Modeling of Wettability Alteration during Spontaneous Imbibition of Mutually Soluble Solvents in Mixed Wet Fractured Reservoirs

M. Chahardowli[1], H. Bruining[1]
[1]Delft University of Technology, Delft, The Netherlands

Mutually-soluble solvents can enhance oil recovery both in completely and partially water wet fractured reservoirs. When a strongly or partially water-wet matrix is surrounded by an immiscible wetting phase in the fracture, spontaneous imbibition is the most important production ... Read More

Modelling Flow through Fractures in Porous Media

E. Holzbecher[1], W.L. Wah[1], and M-S. Litz[2]
[1]Georg-August Universität Göttingen, Germany
[2]Freie Universität Berlin, Germany

There are various alternative options concerning modeling fluid flow within fractures in porous media. We give a general overview, with remarks concerning the modeling using COMSOL Multiphysics. Moreover we define and study two test cases for intercomparison. Finally for one of the ... Read More

Modeling and Characterization of Piezoelectric Structures: From Bulk Material to Thin Film

M. Bavencoffe [1], N. Tembhurnikar [1], B. Negulescu [2], J. Wolfman [2], G. Feuillard [1]
[1] INSA Centre Val de Loire, GREMAN, UMR CNRS 7347, 3 rue de la Chocolaterie, 41034 Blois, France
[2] François Rabelais University, GREMAN, UMR CNRS 7347, Parc de Grandmont, 37200 Tours, France

With the development of micro and nanotechnologies, integrated structures based on piezoelectric thin films are widely investigated and their characterization become a crucial issue for the development of new applications. A laser interferometry is here used to assess the mechanical ... Read More

CFD Simulation of Pore Pressure Oscillation Method to Measure the Permeability of Tight Formations

M. Mokhtari [1], S. A. Madani [1], A. Seibi [1],
[1] Department of Petroleum Engineering, University of Louisiana at Lafayette, Lafayette, LA, USA

Accurate estimation of rock permeability and porosity play a crucial role in the evaluation of oil and gas reservoirs. This evaluation is, however, challenging in tight formations such as shale due to the slow transition of fluid in such formations with extremely-low permeability. To ... Read More

Full Coupling of Flow, Thermal and Mechanical Effects in COMSOL Multiphysics® for Simulation of Enhanced Geothermal Reservoirs

D. Sijacic[1], P. Fokker[1]
[1]TNO, Utrecht, The Netherlands

The effective modeling of enhanced geothermal systems (EGS) requires the coupling of geomechanics, fluid flow and thermal processes. An understanding of the complete system with these coupled processes is vital, not just for reservoir stimulation targeted at enhancing reservoir ... Read More
