The Microwave Electrothermal Thruster (MET) is a space electric propulsion device that uses an electromagnetic resonant cavity within which a free-floating plasma is ignited and sustained, heating a propellant gas that is that exhausted out of a gas-dynamic nozzle. For an empty cavity ... Per saperne di più
Kejako is developing a non-invasive solution for demanding presbyopia patients seeking to keep their quality of life through the compensation of visual accommodation decay. The company has already developed the first and proprietary 3D parametric model of the complete eye. The model ... Per saperne di più
Active noise control systems have recently been proposed and implemented on domestic window apertures. However, their fundamental limits, and performance in the presence of glass windows has not been studied in detail. The passive acoustic attenuation through an aperture covered with ...

The results of modeling of thermal fields, stresses, deformations and displacements in formation of an additive structure from structural low alloy steel for welding 09G2S on a substrate are presented. An interdisciplinary research computational package COMSOL Multiphysics® was used for ... Per saperne di più
Cake batters are complex fat-in-water emulsions with four bulk phases (aqueous, fat, gas, and solid starch granules). The process of cake baking is very complex since a change in thermo-physical properties of batter take place during this process. The aim of this project is to develop an ... Per saperne di più
The formulation of bimodular stress field is based on stress dependent elasticity and the simulations have been carried out using commercial finite element software COMSOL Multiphysics® software. The complexity of the problem is enhanced due to adding bimodular stress field in the ... Per saperne di più
在过去的二三十年中，液体燃烧电弧被用来制造纳米碳结构。该方法利用电弧空间中存在的碳蒸气作为电极腐蚀的结果，在存在高温梯度的区域迅速冷却时形成碳纳米管和富勒烯。碳结构的形成速率和结构取决于等离子体环境和形成机制两个方面。目前的研究工作，等离子体环境的形成和从电极表面的碳蒸气的传输是用二维电弧模型计算研究的。利用流动气液界面的传热来确定水的蒸发速率，考虑到电弧辐射对水蒸发的贡献以及碳和水蒸气之间的化学反应。此项研究使用 COMSOL Multiphysics 等离子体模块及传热模块。 Per saperne di più
In our project, we propose an innovative software solution to the problem of electrical arcing risk prediction in high-voltage on-board electronic equipment intended for long-term self-contained use, e.g. in spacecraft conditions. It completely based on so-called “decomposition” approach ... Per saperne di più
Electrowetting occurs with the electrical control of the surface wetting properties through the application of an electric potential. A simulation of electrowetting driven droplet dynamics is performed using the COMSOL Multiphysics level-set method for a sessile droplet and for a ... Per saperne di più
In this paper, a carbon dioxide sensor is introduced. At present many CO2 sensors are available, but they all required power in the order of few watts, therefore they are not suitable for long term unattended operation. This paper gives the brief description of CO2 sensor modeling using ... Per saperne di più
