Plasma Scaling Leads the Transition from 2D to True 3D Models

J. Brcka [1],
[1] Tokyo Electron U.S. Holdings, Inc., Austin, TX, USA

Introduction: In inductively coupled plasma (ICP) systems the inductive antenna is coupled to the excited plasma inside the low pressure gas reactor. A multi-ICP system can be used for increased area processing and provide additional variables for controlling the plasma. However, ... En savoir plus

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

Thermal Stresses in Functionally Graded Metal-Ceramic Plates

E. Gutierrez-Miravete [1],
[1] Rensselaer at Hartford, Hartford, CT, USA

Functionally graded composite materials are attracting interest among design engineers since structural component properties can be designed and customized into finished parts through processing. The controlled variable is the concentration of reinforcing particles at various points ... En savoir plus

Transport Phenomena in the Conversion of an Anaerobic Landfill into an Aerobic Landfill

H. Omar [1], S. Rohani [1],
[1] University of Western Ontario, London, ON, Canada

The world’s landfills are beginning to fill up due to the growing human population. Landfills require land and there will come a time when there will be no land to be used for landfills. A solution that is gaining attraction is the conversion of traditional “dry-tomb” landfills (used for ... En savoir plus

A Flow and Transport Model in Porous Media for Microbial Enhanced Oil Recovery Studies Using COMSOL Multiphysics® Software

M. A. Diaz-Viera [1], A. Ortiz-Tapia [1],
[1] Mexican Petroleum Institute, Mexico City, Mexico

A flow and transport model in porous media was implemented in COMSOL Multiphysics® software to simulate, analyze and interpret Microbial Enhanced Oil Recovery (MEOR) processes at core scale under laboratory conditions. The flow model is biphasic and is based on the oil phase pressure ... En savoir plus

Uncertainty of FEM Solutions Using a Nonlinear Least Squares and Design of Experiments Approach

J. T. Fong [1], N. A. Heckert [1], J. J. Filliben [1], P. V. Marcal [2], R. Rainsberger [3]
[1] National Institute of Standards and Technology, Gaithersburg, MD, USA
[2] MPACT Corp., Oak Park, CA, USA
[3] XYZ Scientific Applications, Inc., Livermore, CA, USA

Uncertainty in COMSOL Multiphysics® software simulations due to (a) model parameter uncertainties and (b) mesh-induced truncation errors, is estimated using a design-of-experiments approach [1, 2, 3], and a nonlinear least squares logistics fit method [4, 5], respectively. Examples to ... En savoir plus

COMSOL Multiphysics® Software and PV: A Unified Platform for Numerical Simulation of Solar Cells and Modules

M. Nardone [1],
[1] Bowling Green State University, Bowling Green, OH, USA

Introduction: Existing solar cell (photovoltaic, PV) device simulation software is either open source with limited capabilities (1D only) [1,2] or extremely expensive with obscure functionality [3]. PV researchers need an accessible and versatile simulation tool to optimize existing ... En savoir plus

Demonstration of Polymer Microring Resonator for Optical Biosensor using COMSOL

Mohd Haziq M.S.[1]
Mohd Hazimimin Mohd Salleh[2]

[1]Department of Information Systems, Kulliyyah of Information and Communication Technology, International Islamic University Malaysia, Kuala Lumpur, Malaysia

[2]Department of Physics, Kulliyyah of Science, International Islamic University Malaysia, Pahang, Malaysia

In this paper, we use a COMSOL Multiphysics® model to demonstrate the potential use of polymer microring resonator structures for optical biosensing applications. When the refractive index of the area surrounding the microring resonator changes, there is a shift in the resonance ... En savoir plus

Optoelectronic Simulation of An Organic Bulk Heterojunction Solar Cell with COMSOL

Koh Wee Sing[1]
[1]Institute of High Performance Computing, Agency for Science, Technology, and Research, Singapore, Singapore

In this project, we developed a 3D optoelectronic model for organic bulk-heterojunction solar cells. We validated our COMSOL Multiphysics® model with experimental data and used our simulation to predict the optical and electrical characteristics of a 3D plasmonic OPV device. This work ...

Rheological Behaviour of Single–Phase Non-Newtonian Polymer Solution in Complex Pore Geometry: A Simulation Approach

P. Idahosa[1], G. Oluyemi[2], R. Prabhu[2], B. Oyeneyin[2]
[1]IDEAS Research Institute/School of Engineering, Robert Gordon University, Aberdeen, United Kingdom.
[2]School of Engineering, Robert Gordon University, Aberdeen, United Kingdom.

One of the most important criteria for evaluating chemical enhanced oil recovery (EOR) processes that use polymers is its rheological behaviour which in turn account for other physical effects of adsorption and resistance factors during polymer-rock interactions. However, complete ... En savoir plus
