The paper addresses a class of problems for modeling and consequently simulating the electromagnetic field radiation pattern from two arms Archimedes spiral coils. The frequency spatial wavelengths relative to the coil dimensions are in a range where the electromagnetic Maxwell’s equations are solved numerically via the RF Module of COMSOL ...

The evaporation process of microscopic drops was investigated by depositing them onto atomic force microscope (AFM) cantilevers and measuring the deflection of the cantilever in response to the presence of the drop. We could thus improve a previously presented FE simulation model by comparing the simulations of the cantilever’s transversal deflection to 3-D images of the cantilever’s ...

In this paper, we perform a leakage analysis fitted to approximate analytical diffusion and air exchange models, by the helium injection method for one mobile phone type. In order to extend the applicability of our models, we developed a more complicated numerical model for diffusion, thermal conduction and free convection inside the phone.

This paper describes the benefits of computational fluid dynamics in the development of a microreactor used in the desulfurization of aromatic compounds. It is crucial to verify diffusion and extinction coefficients to ensure accurate simulation results prior to experiments. COMSOL Multiphysics was used to model the behavior of all of the possible species present and reactions that may occur.

In an attempt to understand the mechanism and function of NAD(P)H waves in neutrophils, we have constructed a spatial model of glycolysis in neutrophils. The model does give rise to traveling NADH waves, but there are significant differences between the experimentally observed waves and the waves generated by the model. Based on the model we therefore conclude that it is doubtful that the ...

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 ...

Forced and free convection flow in a vertical isothermal circular duct is studied by taking into account the internal heating due to viscous dissipation. The momentum and energy balance equations lead to a nonlinear boundary value problem that is solved numerically by means of the finite-element software COMSOL Multiphysics.For any prescribed value of the average velocity smaller than a maximum, ...

Volcanic margins are characterized by excessive magmatic activity. One of the most studied volcanic margins is the Vøring margin, offshore mid-Norway. The large volumes of magmatic rocks found there are believed to have been produced by the melting of an abnormally hot mantle. We use COMSOL Multiphysics to investigate the hypothesis that the source of this thermal anomaly was a mantle ...
