COMSOL® and MATLAB® Integration to Optimize Heat Exchangers Using Genetic Algorithms Technique
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 ... En savoir plus
Application of Solution Mapping to Reduce Computational Time in Actively Cooled Power Electronics
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 ... En savoir plus
A Numerical Simulation of Adsorption Using Non-Standard Isotherm Equations in COMSOL
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 ... En savoir plus
COMSOL Modeling of a Submarine Geothermal Chimney
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 ... En savoir plus
Fully Coupled Thermo-Hydro-Mechanical Modeling by COMSOL Multiphysics, with Applications in Reservoir Geomechanical Characterization
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 ... En savoir plus
Coupled Electromagnetics-Multiphase Porous Media Model for Microwave Combination Heating
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 ... En savoir plus
Simulation of Manufacturing Process of Ceramic Matrix Composites

Residual Stresses in a Panel Manufactured Using EBF3 Process
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 ... En savoir plus
Identification and Analysis of Low-Frequency Cogging Torque Component in Permanent Magnet Machines
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 ... En savoir plus
