Modelling of SiC Chemical Vapour Infiltration Process Assisted by Microwave Heating

G. Maizza[1] and M. Longhin[1]
[1]Dipartimento di Scienza dei Materiali ed Ingegneria Chimica, Politecnico di Torino, Torino, Italy

The excessive presence of residual SiC matrix inter-fiber pores is often the main cause for the very poor mechanical strength and toughness of SiC/SiC composites manufactured by CVI (Chemical Vapour Infiltration) process. This work presents a micro/macro Microwaveassisted Chemical Vapour ... En savoir plus

A Study of Optical Sensor Based on Fiber Bragg Grating Using COMSOL Multiphysics^®

C. Gavrila[1] and I. Lancranjan[2]

[1]Technical University of Civil Engineering Bucharest, Bucharest, Romania
[2]Advanced Study Centre, National Institute for Aerospace Research “Elie Carafoli”, Bucharest, Romania

Fiber optic sensors can measure a large range of physical, chemical and environmental variables such as temperature, pressure, shape, position, chemical concentration, moisture, etc. Fiber optic sensors provide measurements in applications where the conventional electrical based sensors ...

Modeling of an Optical Black Hole with True Gaussian Beam Incidence

X. Ni[1], A. Kildishev[1], E. Narimanov[1], and L. Prokopeva[2]
[1]Purdue University, West Lafayette, IN, USA
[2]Russian Academy of Sciences, Novosibirsk, Russia

We model an ideal optical black hole device in COMSOL Multiphysics as an electromagnetic scattering problem. The device is illuminated with a Gaussian beam which is focused at a fixed position in horizontal direction (x0) and different positions in vertical direction (y0). The device is ... En savoir plus

This paper describes a type of didactic material used when teaching electromagnetism. The purpose is to guide the students to verify the results of a Finite Element (FE) simulation using those obtained analytically. This procedure has shown to be of great help during their learning of ... En savoir plus

Computation of Electrical Parameters for Different Conducting Bodies Using Finite Element Method

S. Musa and M. Sadiku
College of Engineering, Prairie View A&M University, Prairie View, TX, USA

Accurate and efficient computation of electrical parameters for different conducting bodies represents an essential part of spacecraft modern integrated circuits. In this paper, we will illustrate modeling of inhomogeneous quasi-TEM shielded rectangular, cylindrical, and triangular ... En savoir plus

Finite Element Analysis of Ferrofluid Cooling of Heat Generating Devices

T. Strek
Institute of Applied Mechanics, Poznan University of Technology, Poznan, Poland

An external magnetic field imposed on a ferrofluid with a temperature gradient, results in a non-uniform magnetic body force, which leads to a form of heat transfer called thermomagnetic convection. A magnet placed near the device will always attract the colder ferrofluid more than ... En savoir plus

The Birefringence Change of Optical Fiber Polarizer with Fe-C Film in Corrosive Solution

胡文彬 [1], 丁立康 [1], 朱诚 [1], 袁银权 [1],
[1] 武汉理工大学光纤传感国家工程实验室

The detection of early corrosion is a key issue to mitigate the damage induced by metal corrosion. The optical fiber corrosion sensor based on a side-polished polarizer is realized recently. The polarizer is fabricated by sputtering a Fe film on a side-polished single mode fiber. The new ... En savoir plus
