This work aims at the modelling of a 5 cm^2 Direct Methanol Fuel Cell (DMFC) with mixed serial/parallel serpentine flow fields in terms of current/voltage behaviour. The geometrical design of the single cell is presented in figure 1. The function principle as well as the electrochemical ... En savoir plus
For the commercialization of membraneless microfluidic fuel cell, voltage and minimum power demand for various applications need a precise selection of fuel and oxidant flow rates to achieve the optimum cell performance. A numerical study on a membraneless microfluidic fuel cell was made ... En savoir plus
High levels of Indoor Air Quality (IAQ) in Operating Theatres (OT) is an important issue in order to contribute in prevention of Surgical Site Infections (SSI). Despite of specific plant layouts are applied for OT ventilation (e.g. unidirectional flow), the effective use conditions can ... En savoir plus
The scientific method requires techniques for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge [1]. The Oxford English Dictionary defines the scientific method as "a method or procedure that has characterized natural science since the ... En savoir plus
Venovenous extracorporeal life support (VV-ECLS) provides gas exchange support for severe lung failure by using an extracorporeal circuit consisting of a blood pump and an artificial membrane lung. Blood is withdrawn from a cannula placed into the inferior vena cava, and returned from ... En savoir plus
Standing column wells (SCW) are open-loop geoexchange systems used to provide space heating and cooling to buildings. As they use groundwater as heat carrier fluid and modify its thermo-chemical conditions along the year, they may favor calcite dissolution and precipitation, thus ... En savoir plus
This presentation describes the numerical simulation model where gas/liquid two-phase porous media flow equations are coupled to multicomponent gas-phase transport and water-phase transport equations in COMSOL Multiphysics. This is done in order to predict the landfill stabilization ... En savoir plus
Introduction Among the advanced oxidation processes (AOPs) for removal of volatile organic compounds (VOCs) from air, photocatalytic oxidation (PCO) is considered a very promising technology [1,2]. PCO can achieve mineralization of harmful VOCs to CO2 and H2O using only UV light [3]. A ... En savoir plus
CO₂ geological storage can help to provide a “bridge” from a fossil-fuel dependent system to a more diversified energy portfolio. Pressure monitoring for an injection zone (IZ) and an above-zone monitoring interval (AZMI) has been under operation at a field-scale CO₂ injection site, ... En savoir plus
Examples of Electromagnetic processes are presented: (1) cold crucible, (2) electromagnetic pump, (3) DC electromagnetic brake. A combined approach by using multiphysics modeling with Comsol and experimental validation is used in order to give some guidelines for process improvement and ... En savoir plus
