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 ... Mehr lesen
The efficiency of the first and second generations of solar cell has hardly seen dramatically increase over the years, in which most PV cells cannot use about 55% of the energy of sunlight because a single material can not capture the entire spectrum of sunlight. To achieve the objective ... Mehr lesen
Prototype Fast Breeder Reactor (PFBR) has two independent, diverse, fast acting & fail safe shut down systems to achieve the required level of safety & reliability (1). The shut down systems comprises of nine numbers of Control & Safety Rod Drive Mechanisms (CSRDM) & ... Mehr lesen
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 ... Mehr lesen
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, ... Mehr lesen
The most common cause of lithium ion battery failure is high temperature. Improper thermal management strategies can contribute to the temperature related premature battery failure. Excessive heat significantly impacts the performance, safety and cycle lifetime of the lithium ion ... Mehr lesen
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 ... Mehr lesen
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 ... Mehr lesen
Dissolution of calcite plays an important role in various processes such as enhanced oil and gas recovery, CO2 sequestration, and groundwater transport for the drinking water production. Dissolution rates predicted by pore scale and continuum scale models are often faster than the ... Mehr lesen
Innovations in air-conditioning and other forms of cooling or ventilation can be viewed as technological solutions improving environmental conditions that are beneficial for human health, comfort and productivity. This study deals with a thermal and fluid-dynamics investigation of ... Mehr lesen
