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. ...

Erosion Of Buffer Caused By Groundwater Leakages Based On ESM-Application

O. Punkkinen[1], A. Jorma[1], K. Kari[2], and M. Olin[3]
[1]B+Tech, Helsinki, Finland
[2]Posiva, Eurajoki, Finland
[3]VTT, Espoo, Finland

In this work the issue of saturation phase erosion caused by groundwater leakages was approached both experimentally and computationally by employing COMSOL\'s Earth Science Module. We evaluated the total mass of eroded bentonite out of a cylindrical erosion channel both numerically and ... En savoir plus

Delamination of Sub-Crustal Lithosphere

P. Vincent[1], E. Humphreys[2]
[1]College of Earth, Ocean, & Atmospheric Sciences, Oregon State University, Corvallis, OR, USA
[2]Department of Geological Sciences, University of Oregon, Eugene, OR, USA

Introduction: Lithospheric delamination beneath the western U.S. is believed to be the driving mechanism responsible for the evolution of magmatic and topographic features observed at the surface in the western U.S.. This process requires hot asthenosphere to be in contact with the ... En savoir plus

High Curvature Bending of Ultra-Thin Chips and Chip-on-Foil Assemblies

D. van den Ende[1]
[1]Holst Centre / TNO, Eindhoven, The Netherlands

Ultra-thin chips of less than 20µm become flexible, allowing integration of silicon IC technology with highly flexible electronics. This combination allows for highly intelligent products of unprecedented thinness, flexibility and cost. Examples include sensor systems integrated into ... En savoir plus

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 ... En savoir plus

Laser Assisted Brazing of Titanium to Aluminum Alloy

I. Tomashchuk [1], P. Sallamand [1], M. Duband [1],
[1] Laboratoire Interdisciplinaire Carnot de Bourgogne, Université de Bourgogne-Franche-Comté, Comté, France

Laser assisted brazing with Al-Si fillers in V-shaped groove configuration is a perspective method for joining of aluminum alloys to titanium. The present work introduces multiscale model that allows estimating diffusion process at titanium/melted zone interface in function of thermal ... En savoir plus

Computational Analysis on Commercially Available Stent Designs

K. Basu[1], P. Ghosh[2], S. Bhattacharjee[2], S. Das [2], A. Chanda[1]
[1]School of Bio Science and Engineering, Jadavpur University, Kolkata, West Bengal, India
[2]Department of Mechanical Engineering, Jadavpur University, Kolkata, West Bengal, India

Cardiovascular disease has become a major healthcare problem. To tackle this along with bypass surgery, the use of the cardiovascular stent is considered promising and effective. In this study, we aim to find the effectiveness of stent deployments and their influence on haemodynamics ... En savoir plus

Modeling Self-Potential Effects during Reservoir Stimulation in Enhanced Geothermal System

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

Geothermal systems represent a large resource that can provide, with a reasonable investment, a very high and cost-effective power generating capacity. Despite its unquestionable potential, geothermal exploitation has long been perceived as limited, mainly because of the dependence from ... En savoir plus

Design and Characterization of a Novel High-g Accelerometer

S. Heß, R. Külls, and S. Nau
Fraunhofer Ernst-Mach-Institut
Efringen-Kirchen, Germany

The Fraunhofer Ernst-Mach-Institute (EMI) developed a novel, high-g accelerometer, which is an undamped MEMS device, containing self-supporting piezoresistive elements. The main requirements for such a sensor are high sensitivity, high resonant frequency and a solid mechanical design. ... En savoir plus

Estimation of Fluid Pressure in the Process of Magneto-rheological Flow Finishing

S. Chothe[1], P. Ranjan[1], Dr. P.M. Pawar[1], A.B. Shinde[1]
[1]SVERI's College of Engineering, Pandharpur, Maharashtra, India

This paper presents the 3D model of pressure distribution in the process of magneto-rheological flow finishing. The effect of working gap on pressure distribution is studied using COMSOL Multiphysics® software. Also, the effect of different viscosity of fluids on development of pressure ... En savoir plus
