Simulation and Analysis of Two Fans Air Speed Match Design in Off-Road Mine Tract Generator Using COMSOL

Y. Shen[1], D. Wu[1]
[1]Beijing University of Science & Technology, Beijing, China

This paper describes a model of self-ventilated generator cooling on a 170 tons off-road mine dump truck. Considering the space restrictions of mine dump truck, the cooling systems for the generator and the in-wheel motors of the rear axle share one air inlet duct. With the action of ... En savoir plus

Analysis of a Three-phase Transformer Using COMSOL Multiphysics and a Virtual Reality Environment

A.Buchau, and W. M. Rucker
Institut für Theorie der Elektrotechnik
Universität Stuttgart
Stuttgart, Germany

The simulation software COMSOL Multiphysics is applied to the numerical com-putation of the magnetic fields of a three-phase transformer. A three-dimensional model of the geometrical configuration is created with the help of the CAD tools of COMSOL Multiphysics. There, all dimensions of ... En savoir plus

Simulation of Light Coupling Reciprocity for a Photonic Grating

V. Kivijärvi[1], M. Erdmanis[1], I. Tittonen[1]
[1]Aalto University, Department of Micro- and Nanosciences, Espoo, Finland

SOI (Silicon on Insulator) technology utilizes silicon components on SiO2 layer. Propagating electric field distribution in a SOI waveguide is called mode of the waveguide. Photonic gratings are formed by etching grooves on the top of a waveguide. Gratings can operate in two directions. ... En savoir plus

Multiphysics Analysis of a Thermo-Acoustic MHD Inductive Generator

R. Forcinetti [1], S. Carcangiu [1], A. Montisci [1],
[1] DIEE, University of Cagliari, Cagliari, Italy

Magneto-Hydrodynamic (MHD) power generation systems were originally investigated starting from the fact that the interaction of a plasma with a magnetic field must take place at much higher temperatures than could be observed in a mechanical turbine. The main problems of traditional MHD ... En savoir plus
