This presentation is concerned with the modelling of deformable non-Newtonian Flow using COMSOL Multiphysics. This general modelling approach has more concrete applications such as paper coating in a metering size press, meniscus location by PIDS to mention a few.

The paper presents a two-dimensional model to describe the gas flow in a propane autothermal reactor, developed at the CNR-ITAE Institute, and aimed to design a Beta 5 kWe hydrogen generator, named HYGen II, to be used with Polymer Electrolyte Fuel Cells (PEFCs) for residential applications. The main aim of the mathematical model was to optimize the reactor geometrical key parameters (diameter ...

The so-called opposite electrode pair measurement strategy is adapted in a filtration/expression cell filled with a model material packed bed. In this paper, we investigate the electrical properties of a packed bed, with particular emphasis on its overall conductivity. As a special case study we treat potassium chloride solutions, using model materials of different particle sizes.

The Giant Magneto Resistance (GMR) effect is a quantum mechanical effect which can be observed in systems consisting of thin alternating ferromagnetic and non-ferromagnetic layers. Simulation using COMSOL allows the evaluation of the magneto-resistance ratio and the electrical resistances of realistic CPP-GMR devices and opens the possibility to study new device materials and designs.

Deformable medical image registration is studied with two models developed using COMSOL Multiphysics. One is based on the plane strain application mode and the other on the moving mesh (ALE) application mode. The models are examined by registering gross target volumes of a head-neck tumor with two sets of CT images. The comparison shows that the registration using the moving mesh (ALE) ...

It has become common place to use micro-electromechanical systems (MEMS) to evaluate the chemical properties of solutions. However, such microchips have not yet been applied to the analysis of radioactive solutions, for the purpose of nuclear safeguards, in the nuclear reprocessing industry. Implementing MEMS in this area results in a reduced volume of the sample to be analysed. This has many ...

Virtual prototyping is used for understanding, verifying, planning, controliing, and optimizing a technical application. It the industrial component computational science and engineering and can be called "the third pillar of modern science". The future of virtual prototyping will be multiscale and multiphysics models and simulations. --------------------------------- Keynote speaker's ...

A commercial heat probe is used for energy transfer measurements on copper and silicon substrates. To do so, the micro sensor has to be calibrated under high vacuum (~10-7 mbar), using a homemade black body as a heat source.Although the HFM is cooled at 5 oC, the solid surface temperature is unknown as the thermal contact resistance. Thus, COMSOL simulations are also used to obtain reliable ...

Strain induced by local deformation of a flexible micrometer-sized semiconductor tube is quantified by modeling a ball pressing on the tube wall. By changing the pressing condition, we are able to change the strain state of the tube wall incorporating self-assembled quantum dots (QDs) in the wall. The QD emission energy is calculated in COMSOL® by solving the Schrödinger wave equation ...

New geothermal energy sources hold promise for the future. Deep submarine geothermal energy related to hydrothermal vents is emerging in many places along the oceanic spreading centers. Shallow submarine geothermal systems are found near to continental platforms. We present the initial development of mathematical models to simulate the energy transport in submarine systems. A model for the ...
