A COMSOL Multiphysics® model of our apparatus has been created in order to simulate the pressurizations of our nanoparticles by Deuterium. Using reference measurements during a cooling process, we calibrated the model so that its thermal aspects reflect the ones of our experimental set up. To reproduce the pressurizations, the following variables are parameters : the location of the heat ...

In clean coal technologies, improving energy conversion efficiency is one of the most important directions. Compared to traditional subcritical power plants, pressure-increased supercritical power plants improve the plant energy efficiency from 35% up to 45%. This work presents a study of the thermodynamic behaviour of the water cycle in coal-fired boilers in response to the changes in energy ...

Magnetorheological Elastomers (MREs) are a composite that consist of magnetic micrometer sized particles suspended within rubber matrix filler. By placing this material within an external magnetic field during the rubber curing process, the poles of the particles are forced to align and form chains of particles within the matrix. These chains cause the MRE to change its stiffness properties when ...

To consider effective counter measures against ground water contaminated with dense non-aqueous phase liquids (DNAPLs) such as chlorinated solvents, it is first important to understand the mechanism of their migration in heterogeneous aquifer. In addition, numerical analysis models to simulate such a complex migration in heterogeneous aquifer are required. The displacement pressure, which ...

Among the several types of capacitors, the double-layer and redox types have gathered increasing attention to address some of the heavy power demands of modern technology. In redox capacitors, charge is stored chemically via oxidation/reduction processes in the active materials like electroactive polymers (EAPs) or metal oxides. This work investigates the stresses and heat flux of the electrode ...

Enzymatic biofuel cells (EBFCs) are miniature, implantable power sources, which use enzymes as catalysts to perform redox reaction with biological fuels such as glucose. In this study using COMSOL Multiphysics, we use an EBFC chip, having three dimensional, highly dense micro-electrode arrays, fabricated by C-MEMS micro-fabrication techniques. Glucose oxidase (GOx) is immobilized on anodes for ...

Monitoring of indoor CO2 concentration is of particular interest to detect room occupancy in order to optimise power consumptions of building. One technological approach is to use optical detection using specific absorption lines of CO2 molecules in the infrared domain close to 4.2 μm. Key features for a wider use in public and private buildings are power consumption and price. Such optical ...

The modeling of sublimation form a rotating cylinder of solid naphthalene in a confined vessel has been performed by coupling the model of incompressible Newtonian fluid flow with the model of the dilute solutions. Preliminary a 2D axisymmetric system with swirl flow function for laminar and turbulent regimes has been considered. In the turbulent regime the RANS model with default parameter ...
