COMSOL as an Aid in the Teaching (Learning) of Heat Transfer
Several undergraduate programs include the “Heat transfer” subject and, in our experience, it is hard for the students to grasp the concepts that are presented in the course. With this in mind, we designed and constructed an apparatus for the experimentation of heat transfer in a short ... En savoir plus
Modeling of Chloride Transport in Cracked Concrete: a 3-D Image–Based Microstructure Simulation
The prediction of concrete materials service life is not easy, because the complex heterogeneous microstructure and the random nature of concrete materials. Study the presence of cracks in concrete and their effect on coupled reaction and transport are of great interest in civil ... En savoir plus
Load Cell Design Using COMSOL Multiphysics
COMSOL Multiphysics was used to design a binocular load cell. A three-dimensional linear solid model of the load cell spring element was studied to quantify the high-strain regions under loading conditions. The load cell was fabricated from 6061 aluminum, and general purpose Constantin ... En savoir plus
Development of the Service Frame for SBS Tracker GEM and TENDIGEM Development
The Gas Electron Multiplier (GEM) technology has been proven to tolerate rate larger than 50 MHz/cm² without noticeable aging and to provide the sub-millimeter resolution on working chambers up to 45x45 cm² [1]. A new GEM tracker is under development for the upgrade of the SBS ... En savoir plus
Multiphysics Software Applications in Reverse Engineering
During the past decade reverse engineering has become a common and acceptable practice utilized by many aftermarket suppliers, and even original equipment manufacturers (OEM). This presentation focuses on the applications of multiphysics software such as COMSOL and Simpleware® in ... En savoir plus
Finite Element Convergence and Speed-Up Studies Using COMSOL Multiphysics and LiveLink™ for MATLAB® with Large Assembly Models
COMSOL Multiphysics along with its LiveLink™ for MATLAB® is used to investigate the needed number of elements and the required order of Lagrangean p element for a number of different simulation models. For this task, convergence study, speed up testing and interactive meshing is ... En savoir plus
Early Stage Melt Ejection in Laser Percussion Drilling
Laser percussion drilling is widely used in the aerospace industry to produce cooling holes in jet engine components. This process is a thermal, contact-free process which involves firing a sequence of focused optical pulses onto a target material [1-4]. During each optical pulse, the ... En savoir plus
Irrotational Motion of an Incompressible Fluid Past a Wing Section in an Unbounded Region
Developers of numerical models who address the title problem face several hurdles, such as: (1), the need to formulate boundary conditions applicable in an unbounded region; (2), The need to specify conditions suitable to ensure a unique solution in a doubly connected region; and (3), ...

Multiphysics Modeling of Warm-Air Drying of Potatoes Slices
In this work we solve a model to simulate the drying of potatoes slices. The model considers both the transport of free and vapor water by applying a mechanistic approach. The critical moisture point (CMP) was considered, since it is a transition zone and it represents the point where ... En savoir plus
Topology Optimization of Dielectric Metamaterials Based on the Level Set Method Using COMSOL Multiphysics
This presentation shows a level set-based topology optimization method for the structural design of negative permeability dielectric metamaterials incorporating the level set boundary expression based on the concept of the phase field method, and its optimization algorithm implemented ...
