[2] Grupo Automática y Diseño
[3] Instituto de Energía y Termodinámica, Mechanical Engineering Faculty, Universidad Pontificia Bolivariana, Medellin, Antioquia, Colombia

Genetic Algorithms (GA) have proved to be a complete and effective approach for solving optimization problems. This article presents the integration between COMSOL® and a GA optimization tool coded in MATLAB® for the optimization of two thermal systems: a constant area fin in 2D and a ... Read More

Application of Solution Mapping to Reduce Computational Time in Actively Cooled Power Electronics

K. Lowe [1,2], and Rao V. Arimilli[2]
[1]Oak Ridge National Laboratory, Oak Ridge, TN, USA
[2]Department of Mechanical, Aerospace, and Biomedical Engineering, University of Tennessee, Knoxville, TN, USA

In some power electronic applications the available coolant temperature is close to maximum and controlling operating temperature becomes more challenging, for which new thermal management schemes must be considered. COMSOL predicts the 3D fluid behavior and 3D temperature distribution ... Read More

A Numerical Simulation of Adsorption Using Non-Standard Isotherm Equations in COMSOL

A. Ortiz-Tapia, D. Lopez-Falcon, M. Diaz-Viera, S. Lopez-Ramirez, and J. Mendoza-dela-Cruz
Instituto Mexicano del Petroleo, D. F., Mexico

Numerical simulations of the equation of transport were performed using an adsorption isotherm equation, and a simple cubic polynomial. The 1D COMSOL implementation included solutes being injected from one face of a homogeneous, isotropic core (small sample of reservoir rock); where the ... Read More

COMSOL Modeling of a Submarine Geothermal Chimney

M. Suárez [1], and F. Samaniego [2]
[1]Faculty of Sciences, Michoacán University (UMSNH), Morelia, Michoacan, Mexico
[2]Faculty of Engineering Postgrade Studies Division, National University of Mexico (UNAM), Mexico City, Mexico

New geothermal energy sources hold promise for the future. Deep submarine geothermal energy related to hydrothermal vents is emerging in many places along the oceanic spreading centers. Shallow submarine geothermal systems are found near to continental platforms. We present the initial ... Read More

Fully Coupled Thermo-Hydro-Mechanical Modeling by COMSOL Multiphysics, with Applications in Reservoir Geomechanical Characterization

T. Freeman[1], R. Chalaturnyk[1], and I. Bogdanov[2]
[1]University of Alberta, Edmonton, AB, Canada
[2]Centre Huile Lourde Ouvert et Expérimental (CHLOE), France

Because of the complex nature of geomaterials and presence of solid and fluid within a single system, it is crucial to consider all the physics involved within the geomaterial system. A fully coupled thermo-hydromechanical model is developed. The model consists of a three-phase flow ... Read More

Coupled Electromagnetics-Multiphase Porous Media Model for Microwave Combination Heating

V. Rakesh, and A. Datta
Dept. of Biological and Environmental Engineering, Cornell University, Ithaca, NY, USA

Although microwave heating has been studied in great detail, microwave combination heating has not. This work investigated this in a novel microwave combination system that heats the sample through a combination of microwaves and hot air. The study used a coupled electromagnetics ... Read More

Simulation of Manufacturing Process of Ceramic Matrix Composites

S. Yushanov, J. Crompton, and K. Koppenhoefer
ACES of Columbus, LLC, Columbus, OH, USA

Improved performance of aeroengines requires the development of new manufacturing technologies for ceramic matrix composites (CMCs). This has been simulated using COMSOL Multiphysics. Specialized simulation technologies have been developed to describe the infiltration of molten material ... Read More

[3] Aerospace and Ocean Engineering Department, Virginia Polytechnic Institute and State University, Blacksburg, Virginia, USA

The residual stresses developed in a stiffened panel manufactured using Electron Beam Freeform Fabrication (EBF3) process were studied. EBF3 process is a layer additive process that can be used to build near-net shaped parts directly using computer controlled techniques, which can be ... Read More

Identification and Analysis of Low-Frequency Cogging Torque Component in Permanent Magnet Machines

D. McIntosh
Sonsight Inc. / NSWC, Accokeek, MD, USA

Cogging torque in permanent magnet motors and generators is characterized by a torque ripple. These torque fluctuations cause vibrations, noise and speed fluctuations. This paper presents finite element (FE) analyses results that show a previously unaddressed low frequency modulation of ... Read More
