Oxygen transfer through ceramic membranes at high-temperature can substantially reduce costs respect to conventional separation methods. With the aim to improve the determination of the properties of the ceramic materials, a lab-scale permeation set-up was modeled using the Chemical ... Read More
HazRes has developed a gas discharge and dispersion model in COMSOL which takes into account the effects of localized wind profiles and turbulence generated by buildings, structures and terrain on the dispersion of gases in question. The main focus of this work is to develop and provide ... Read More
We use finite elements simulations in order to study the fluid flow behavior in a chamber of a preconcentrator. We realized that most part of the fluid does not affect our preconcentrator because it is going out the chamber at high distance above it and parallel to the preconcentrator. ... Read More
A two-dimensional mathematical model for the absorption and desorption of H2 in LaNi4.8Al0.2 was developed and experimentally validated. The model is composed of an energy balance, a mass balance and a momentum balance. These differential equations are numerically solved by means of the ... Read More
In recent years lab-on-microchip technology has become a powerful tool for micro-scale analysis of biochemical processes. In the studied system the overall process consists of transport, convection, diffusion, reaction and adsorption processes. Two compounds A and B, contained in a ... Read More
The self heating process of Tetrafluoroethylene caused by an exothermic dimerization reaction was studied. The heat of reaction can lead to a thermal explosion by the decomposition of the Tetrafluoroethylene. Different reaction kinetics, including multistep kinetics, were used to ... Read More
One of the primary reasons for large power fluctuations in smelting furnaces is loss of contact between the electrode and ore. Therefore one of the important aspects of controlling power fluctuations is a predictive algorithm for the positioning of the electrode. We propose a model ... Read More
In Eiceman and Karpas’s book Ion Mobility Spectroscopy (2005), they define Ion Mobility Spectroscopy (IMS) as "the principles, methods, and instrumentation for characterizing chemical substances on the basis of velocity of gas-phase ions in an electric field." The production of the ... Read More
Verification of the codes applied for assessment of the long-term repository safety is typically one of the quality assurance requirements demanded by regulatory bodies, in the disposal of radioactive waste. In this paper, an internationally organized benchmark exercise is presented, in ... Read More
Spark Plasma Sintering (SPS) is a promising rapid consolidation technique that allows a better understanding and manipulation of sintering kinetics and therefore makes it possible to obtain polycrystalline materials (ceramic or metallic) with tailored microstructures. A numerical ... Read More
