We simulate a Capacitive Micromachined Ultrasound Transducer (CMUT) using COMSOL Multiphysics® software. The CMUT is an electromechanical system, therefore, we couple the physics of electrical and structural mechanics to describe its dynamics. We obtain the distributions of the electric ...

The transfer of sucrose and fructooligosaccharides to melon and water to solution was modeled based on generalized form of Fick’s second law for simultaneous diffusion and resolved by the finite element method using the software package COMSOL Multiphysics® software. The diffusion ... En savoir plus
This paper presents an application of COMSOL Multiphysics® software in the study of the temperature distribution of a 5kVA three-phase air-cooled transformer. A 3D, steady state model was utilized on the simulations. The interface with the surrounding air was modeled by Newton's Law of ... En savoir plus
No processo Kraft a madeira é reduzida a uma massa fibrosa. Neste processo são rompidas as ligações entre as estruturas da madeira separando as fibras. Esta operação, denominada de polpação, é realizada em um equipamento denominado de digestor. Este trabalho analisa o comportamento ... En savoir plus
Adsorption heat exchangers (AdHXs) are important components in adsorption heat pumps and chillers, a primary energy efficient source of heating and cooling. Due to availability and established inexpensive manufacturing fin-and-tube type heat exchangers with beds of adsorption pellets in ... En savoir plus
Electromagnetic actuators are representing one important component of ABB's medium voltage reclosers [1, 2]. Their performance is strongly influenced by the considered material properties as well as by the electronic control units that will power the actuator. Depending on the studied ... En savoir plus
A recurring problem, in heat assisted magnetic recording is the build-up of thermal energy in the near-field transducer leading to NFT deformation and the cessation of operation. A mechanism to dissipate this excess heat in the NFT without greatly effecting its’ plasmonic response is ... En savoir plus
Analysis of concrete structures is usually carried out by destructive methods. The internal volume flaws directly influence concrete properties. Such inclusions are empty or even resulting from the manufacturing process or degradation by percolation leaching dissolution and chemical ... En savoir plus
The radiation force effects on the surface displacement can be calculated by solving the Navier-Stokes equation with appropriated boundary conditions. The surface deformation can be described by the radiation pressure as well as those forces due to gravity and surface tension. We used ... En savoir plus
The present work demonstrates that a simple half-cell model is capable of reproducing qualitatively the main features of the measurements of the current density distribution in a high-temperature polymer electrolyte fuel cell, pointing that computational modeling and simulation are an ...
