Development of a Thermal Model Using COMSOL Multiphysics® Software

A. Oukaira [1], A. Lakhssassi [1],
[1] Department of Computer Science, Université du Québec en Outaouais à Hull, Gatineau, QC, Canada

The Purpose of this paper is to develop a thermal model using COMSOL Multiphysics® software that aims to get an idea of the heat flow around the ASIC, as well as to address the thermal issues for integrated circuits at the tongue board. However, we need sources of heat simulations to map ... En savoir plus

Numerical Analysis of the Phase Change in High Power Latent Heat Storages with 3D Wire Structures

A. Schlott [1], J. Hörstmann [2], O. Andersen [1], J. Meinert [1],
[1] Fraunhofer Institute for Manufacturing Technology and Advanced Materials IFAM, Branch Lab Dresden, Dresden, Germany
[2] Denso Automotive Deutschland GmbH, Department Heat Exchanger Application, Eching, Germany

Latent heat storage devices use the melting enthalpy of a so-called phase change material (PCM) to store thermal energy. Open porous metals, such as 3D wire structures, allow the design of systems with tailored storage capacity and power. A geometric unit cell was identified, modelled ... En savoir plus

Electric Field Assisted Formation of Polymeric Hollow Microstructures

Vivek [1], S. Baranwal [1], A. Bindal [1], R. Mukherjee [1], A. Atta [1]
[1]IIT Kharagpur, West Bengal, India

Hollow microstructures find numerous applications in microsystems, bioMEMS and microfluidic systems [1]. Consequently, one-step fabrication process of hollow polymeric microstructures by external electric field along with capillary forces, termed as electric field- assisted capillarity ...

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 ... En savoir plus

Acoustic-Structure Interaction Simulation of a Differential Phase Sensor

J. H. Lee[1]
[1]Department of Mechanical Engineering, American University of Sharjah, Sharjah, UAE

The idea of application as a hearing device based on a parasitoid fly, Ormia ochracea has been studied extensively recently. This paper addresses another possible application as an underwater directional sensor. In order to study the feasibility of the application, it is necessary to ... En savoir plus

Mitigation of Greenhouse Gas Leakage from Oil and Gas Wells

J. S. Crompton [1], H. Spencer [2], J. Thomas [1], K. Koppenhoefer [1]
[1] AltaSim Technologies, Columbus, OH, USA
[2] Seal Well, Calgary, AB, Canada

Pre-existing oil and gas wells and well bores represent highly permeable pathways for leakage of greenhouse gases; in Alberta alone leaks have been estimated to provide the equivalent of 3.5 million tonnes of CO2 per annum. In addition to abandoned wells without plugs, gas leakage may ... En savoir plus

Simulations of Microelectrode and Neuron Interfaces Enable Long-Term and High Fidelity Recordings

P. Wijdenes [1], H. Ali [2], N. Syed [3], C. Dalton [2],
[1] Centre for Bioengineering Research and Education, University of Calgary, Calgary, AB, Canada
[2] Department of Electrical and Computer Engineering, Schulich School of Engineering, University of Calgary, Calgary, AB, Canada
[3] Alberta Children's Hospital Research Institute, University of Calgary, Calgary, AB, Canada

Our inability to record single cell activity with high resolution over a long period of time precludes fundamental understanding of nervous system functions, both under normal and pathological conditions. While the fabrication of current micro- and nano-electrodes has advanced our ... En savoir plus

Si-Infiltrated SiC Lattices in Elevated Temperatures: A Thermo-Mechanical Analysis

E. Rezaei [1],
[1] EPFL, Lugano, Switzerland

Si-infiltrated SiC porous composites exist in different forms composed of cores of cellular ceramic and skin plates of ceramic matrix composites. Due to high thermal conductivity, low coefficient of thermal expansion, high elastic modulus and high strength, the final product can be a ... En savoir plus

Mechanistic Modeling of Non-Spherical Bacterial Attachment on Plant Surface Structures

A. Warning [1], A. K. Datta [1],
[1] Cornell University, Ithaca, NY, USA

The particle tracking model provided a deeper understanding to the experimental results. The model showed good agreement with experimental data for rotation, transport and attachment. In the attachment model, protrusions create low velocity, low shear regions increasing attachment ... En savoir plus

Some Benchmark Simulations for Flash Flood Modeling

E. Holzbecher [1], A. Hadidi [1],
[1] German University of Technology in Oman, Muscat, Oman

Flash floods are sudden and mostly destructive rushes of water down narrow gullies or over sloping surfaces. They are mostly caused by heavy rainfall in the upstream watershed. They may also appear as result of catastrophic events as dam or levee breaks, or mudslides or debris flow. ... En savoir plus
