In this poster, a numerical model of spot pulsed current TIG welding for partially and fully penetrated weld pools is presented. Heat transfer and fluid flow in the weld pool driven by the combination of electromagnetic force, buoyancy force, surface tension gradient and latent heat are ... En savoir plus
Aging infrastructure requires frequent inspections to assess their structural integrity. However, the large amount of existing infrastructure, and the distance between these structures present significant challenges to inspectors. Acoustics-based technologies represent a simple, and ...

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 ... En savoir plus
Studies of poroelastic systems increasingly utilize numerical modeling. Especially for geotechnical applications models are set up as a tool to understand phenomena in porous media that deform due to changes of the hydraulic regime, or in which the flow field is affected by changes of ...

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 ... En savoir plus
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 ...

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 ... En savoir plus
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 ... En savoir plus
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 ... En savoir plus
