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 ...

The assessment of forest soil respiration and its isotopic composition is one of the important issues for the carbon cycling modeling (greenhouse gas emission control) because it is often inaccurate. Soil respiration is a complex process, depending on the coupling of several phenomena, which is therefore highly sensitive to any disturbance. In this work, the dynamics of the transport of two ...

[1]University of Birmingham, School of Chemical Engineering, Edgbaston, Birmingham, UK

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 ...

Computational Modeling of Magnetorheological Elastomers Using Soft and Hard Magnetic Particles

J. Biggs[1], P. VonLockette[1], and S. Lofland[1]
[1]Rowan University, Glassboro, New Jersey

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 ...

Effect of S-p Relation Model on DNAPL Migration Simulation Result

[1]National Institute for Environmental Studies, Tsukuba, Ibaraki, Japan

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 ...

Y. Song, and C. Wang
Florida International University, Miami, FL, USA

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 ...
