Progress in coating technology has allowed for the development of free-chromate corrosion inhibitors, which are able to smartly migrate when required. In order to support the coating design, we propose a hybrid mathematical model to study the inhibitor's release by taking into account ... En savoir plus
In this presentation we are dealing with the computational fluid model of a Filament Assisted Chemical Vapor Deposition (FACVD) reactor. Proposed strategy in this study involved several steps: (a) development a computational model for FACVD process capable to describe and obtain with ... En savoir plus
Disposing of easy-to-use COMSOL Multiphysics® app to exploit FE-based simulations represents an important opportunity for people working in several industrial areas – from the electronics to the process engineering. In supplying consultancy services, Engineers at BE CAE & Test ... En savoir plus
Ventilation is mainly used to control indoor air quality and for the purpose of thermal comfort by diluting and displacing pollutants. Because of the effects it has on health, comfort, and serviceability, indoor air quality in our homes is becoming of increasing concern to many people. ... En savoir plus
Outline of presentation: In electromagnetic technology applications the finite element method is very well suited for a wide range of problem types For many cases, in particular when inhomogeneous materials having complex properties are involved as well as when multiphysics couplings ...

A fundamentally important area of the COMSOL Multiphysics® code is that of equation-based modeling. This root capability is unique in commercially-available codes and offers unlimited application. One specific area that requires more detail, even in the CFD Module of COMSOL®, is that ... En savoir plus
RFSP-IST (Reactor Fueling Simulation Program) is a computer code used for the full-core neutronics design and analysis of CANDU® reactors. RFSP-IST calculates the static flux and power distributions in the core by solving the neutron diffusion equation in two energy groups. For ... En savoir plus
In climates with high temperature and solar radiation, reducing the cooling consumption and increasing the standards of indoor comfort are topics of great importance. The roof plays a key role in controlling the indoor thermal comfort. In ventilated roofs, air flow within the ASV (Above ... En savoir plus
超材料是一类具有天然材料所不具备的特殊性质的材料[1-3]。近年来，有学者开始研究超材料对波的旋转效应，这一研究有着工程应用价值。江雪等[4]设计并实验验证了一种声场旋转器。江雪等[5]进一步研究了声场旋转器整体尺寸大小对其工作带宽的影响及声场旋转器中心处的旋转角度与其结构单元长度的关系。但未见声场旋转器结构单元尺寸对其工作带宽影响的研究。 本文采用 COMSOL Multiphysics® 的声学模块和结构力学模块模拟图1的俯视二维结构，采用完美匹配层以获得更好的模拟结果。 本文模拟了5个声场旋转器在不同频率下的声场，发现随着长方体结构单元长宽比的增加 ... En savoir plus
This paper studies sound energy flows through an aperture across two coupled spaces using a diffusion equation model. The so-called double sloped sound energy decay is believed to be caused by the sound energy exchange through the aperture coupling the two rooms. The room diffusion ... En savoir plus
