Various types of equation system formulations for modeling two-phase flow in porous media using the finite element method have been investigated. These allow for equation manipulation such that the main differences between the formulations are the dependent variables that are solved ... Read More
Concerning the reduction of fossil-energy use from industrial processes, power generation and transportation, concentrated solar power from dish reflectors is well suited for driving highly endothermic reactions that valorize CO2 and/or light hydrocarbons. In this study, a directly ... Read More
The quaternary mirror (M4) of the Extremely Large Telescope will be equipped with an Adaptive Optics Unit, in order to compensate the effects of the atmospheric turbulence. The highly accurate, closed loop actuation of the thin mirror is provided by 5316 contactless actuators. Their core ... Read More
Traditionally, municipal sewer and water agencies have relied on acoustic data loggers and closed-circuit television cameras to inspect pipes for leaks. In addition, the same legacy techniques have been used to certify new and rehabilitated pipes as watertight. Unfortunately, visually ... Read More
气体渗流机制和渗透率演化是预测页岩储层天然气产量的重要因素。本文建立了多场耦合下的基质和裂缝的动态渗透率演化模型，并将其整合到COMSOL求解器中，并利用岩土力学和地下水流模块求解。此外，分析了基质收缩和应力敏感性对渗透率的影响。研究结果表明，孔径增大会增加页岩储层的气体渗流能力。与常规储层相比，由于气体多重流动机制，在小孔（1-10 nm）和低压（0-5 MPa）下，基质表观渗透率与达西渗透率之比高出约1-2个数量级。流动机制主要包括表面扩散，努森扩散和滑移流动。同时基质收缩和应力敏感性的综合影响导致纳米孔闭合，与基质初始渗透率相比，渗透率下降约1个数量级 ... Read More
Manuel Collet is a member of the Department of Applied Mechanics of the FEMTO-ST Institute. He graduated with a degree in Mechanical Engineering from Ecole Centrale de Lyon in 1992 and obtained his PhD in 1996 about Active control of vibrating structures by mean of semi distributed ... Read More
In this study we model the sound attenuation properties of a hearing aid earmold tube. The model includes thermoviscous acoustic effects and it couples structural vibrations to the external acoustic field. Moreover, the finite element domain is coupled at two boundaries with an ... Read More
Finite element modelling of electrical machines usually assumes uniform magnetic properties and loss behaviour throughout the steel laminations. It is well known that manufacturing processes, like the assembly of the machine, deteriorate the properties of the core material. Generally, ... Read More
A two dimensional instationary analysis of the conjugate optical-thermal fields induced in a multilayer thin film structure on a glass substrate by a moving Gaussian laser source is carried out numerically in order to compare back and front laser treatment processes. COMSOL Multiphysics ... Read More
This paper presents a 3D finite element model in COMSOL for the electro-thermal analysis of high power light emitting diodes (LEDs). The proposed model and implementation approach require basic electrical and optical parameters that may be experimentally derived with the aid of advanced ... Read More
