Hydrogen, the most abundant element in the universe, has great potential as an energy source, and can be generated from renewable energy sources. We used COMSOL for the solution of the energy, mass and momentum balance equations that describe the hydrogen absorption and desorption procedure in the metal hydride compressor. Thermodynamic or engineering properties like the reaction enthalpy ??, ...

Computer simulation is mandatory for the optimization of electromagnetic devices. Here we concentrate on two classes of devices operating in the MHz and GHz range, namely microwave ovens and TEM cells for electromagnetic compatibility testing. In particular we concentrate on the issue that numerical results are usually different from the experimental ones and this can be due, among others ...

Electric Field Assisted Capillarity (EFAC) is a novel technique for the fabrication of hollow polymer microstructures. It has advantages over current methods as it is a single step process. Hollow microstructures have many uses in industry from microchannels and microcapsules in BioMEMS to fibre-optical waveguides. It makes use of the dielectric properties of polymers combined with a heavily ...

The energy pay back is one of the most interesting field especially in the steel industry where this contribution is strictly connected to steams and emissions inside and outside the plant. Perhaps, this application is sometimes disturbed by a strong variation of emissions (\"off gas\"). One example is the arc furnace where the process is very discontinuous and there are many fluctuations in the ...

Non-conventional hydrocarbon resources become more and more challenging object for energy producing companies throughout the world. Being already known and long-explored method, the electromagnetically (EM) assisted recovery constitutes a promising idea of technology for deposits of such a kind. COMSOL has been used recently for modeling the thermal multiphase flow through porous media in the ...

A conjugate conductive-convective-radiative discrete model useful for the study and the simulation of heat transfer in a ceramic or metallic foam is presented. A Generation-based Technique is used for the foam representation, using the Weaire-Phelan structure and heat transfer is studied using the COMSOL Multiphysics. The computational domain is made up by a single cell and a fictitious inlet ...

The modeling of light propagation through multiple layers of biological tissue are assessed & compared to the theoretical predictions by Perelman at al. [94 & 95] of the most-favorable-path (MFP). The MFP on which photons will be found can be obtained from the path of the net flux propagation using the diffusion equation. The diffusion equation is valid when studying diffuse light propagation, ...

In this work, we present a number of scoping calculations that have been carried out to design an in-situ redox experiment (Figure 1) focused on assessing potential changes in the pH and redox conditions and in the buffering capacity of the Olkiluoto bedrock (i.e. the site for the Finnish spent fuel repository). A characteristic of these models lies in the need to integrate prior information, ...
