COMSOL Multiphysics has been applied to develop a model for inductive heating. A coarse, lumped model of the interior of a high temperature reactor is coupled to finite element models for the electromagnetic field, the temperature distribution outside the reactor, and mechanical stresses in the crucible. The model can be applied to study operational conditions, thermal stresses, or design details ...

This paper describes a model which simulates a stray current interface of underground steel structures through a traction power system, which causes accelerated corrosion.First preliminary calculations show that uncertainty in the soil resistivity and the train power consumption contribute most in the uncertainty in the maximum interference current density

The imbalance between the four fundamental magnetic interactions (the magneto-crystalline anisotropy, the exchange and magnetostatic interactions, and the Zeeman coupling) is responsible for a very large diversity of magneticbehaviors that researchers try to explore anduse for technical applications (data storage,sensors, memories, medical imaging …).In this work, a finite element formalism ...

Finite element analysis provides new insights into the electrical behavior of conducting adhesives. We show that at a contact between a spherical conducting particle and a flat conducting substrate the current distribution is non-uniform: the current is concentrated at the periphery of the contact. In practice, the current concentration has important implications. We further shed light on what ...

Impedance spectroscopy is a measurement technique that has been investigated in a wide variety of medical applications. An example is the measurement of the dielectric properties of the skin and underlying tissue using sensors placed in contact with human skin with capacitive fringing field electrodes. The aim of this work is to use finite element methods for optimizing the sensor design to ...

CdTe and GaAs 3D semiconductor radiation detectors for medical imaging have been simulated. This was done through coupling Monte-Carlo simulations of interacting of X- and γ-rays with matter (using PENELOPE) while computating the applied potential, weighting field, free charge carriers transport and electrodes Charge Induction Efficiency (CIE) with COMSOL Multiphysics. Since the continuity ...

The effect of metallization thickness on planar transmission lines plays an essential role in microwave integrated circuits and thin film technology, especially in the propagation characterization and the electric field distribution in the structures. The objective of this paper is to consider the planar transmission lines with finite thickness not penetrating and penetrating into isotropic ...

Ion mobility spectrometry provides fast detection of very low concentrations of chemical substances. Simple instrumentation combined with high sensitivity and high selectivity are the advantages of this technique. One well established field of application is the detection of hazardous compounds in air, such as chemical warfare agents, explosives and pollutants. A numerical model based on finite ...
