The job of designing end-winding corona protection (ECP) system is one of the very important and complex phases for insulation configuration of high voltage rotating machines. This complexity stems on one hand from the highly nonlinear characteristics of the ECP material and on the other hand from the coupled multiphysics phenomena of the involved performance evaluation. Simulation based ECP ...

The design of a RFID-enabled temperature sensor is described in this paper. In this sensor, a change in temperature causes structural beams to bend, which results in a proportional displacement of the plates of the capacitor. Plates\' displacement results, in turn, in changing the value of its capacitance. The capacitor of the sensor is coupled to the LC resonant network of a passive RFID tag. ...

We study the topography influence of levees on the electric resistivity signal obtained with the Radio-Magnetotelluric method. Field measurements have been modeled with COMSOL, using the AC/DC and RF Modules. A levee situated in Orléans along the Loire river (France) has been considered in order to design a model tacking account of the skin depth and the incident wavelength, keeping a constant ...

ELENA is a small cooler decelerator ring at CERN which will be built to increase substantially the number of usable antiprotons delivered to experiments for studies with antihydrogen and antiprotonic nuclei. COMSOL Multiphysics® software has been used to completely model the ELENA electron cooling device in 3D. We have taken advantage of the different physics-based modules of COMSOL ...

The paper addresses a class of problems for modeling and consequently simulating the electromagnetic field radiation pattern from a two arm Archimedes spiral coil. The performance of particular interest is knowledge of the radiated magnetic field H and electric field E in the neighborhood of the coil. The results in this paper illustrate how COMSOL is used to solve for the radiated ...

Superconductors have the unique capability of trapping magnetic flux. This feature has the potential to enable and improve several applications including high power density rotating machines. Current material used as trapped flux magnets (TFM) is single domain YBCO that present numerous limitations interms of performance, stability and size. One way to overcome the limitations is to use thin ...

In this article, the aim is to study different types and forms of electromyography (EMG) electrodes, for bipolar configuration, and the electric interface with muscle phantom. COMSOL Multiphysics allows modeling shapes and contact surfaces. Surface and needle electrodes will be modeled. A number of different trials and combinations will be presented; exploring different geometric shapes and ...

The TS (Turin Shroud) [1,2] is a fine linen fabric showing a not yet explainable  double body image of a scourged and crucified man stabbed on the side. Many hypotheses have been formulated without success  and perhaps the most reliable is one correlated to the Corona Discharge  that supposes the presence of an intense electric field, amplified by the presence of ionization induced by ...

We show a new, favourable space-saving method to host a neutron polarizer in the iron-containing monochromator shielding of a time-of-flight spectrometer for cold neutrons. In this poster you can learn e.g., how to create a robust, homogeneous, rectangular magnetic field (here realized by permanent magnet queues inside an iron tube). The time-of-flight spectrometer FOCUS at the spallation ...
