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

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

3-Dimensional Numerical Modeling of Radio Frequency Selective Heating of Insects In Soybeans

S. Wang [1], Z. Huang [1],
[1] Northwest A&F University, Yangling, Shaanxi, China

Radio frequency (RF) heating have potential as alternatives to chemical fumigation for disinfesting legumes. This study was conducted to investigate the feasibility of RF selective heating of insect larvae in 3 kg soybeans packed in a rectangular plastic container using a 6 kW, 27.12 MHz ... En savoir plus

Fully Coupled Thermo-Hydro-Mechanical Modeling by COMSOL Multiphysics, with Applications in Reservoir Geomechanical Characterization

T. Freeman[1], R. Chalaturnyk[1], and I. Bogdanov[2]
[1]University of Alberta, Edmonton, AB, Canada
[2]Centre Huile Lourde Ouvert et Expérimental (CHLOE), France

Because of the complex nature of geomaterials and presence of solid and fluid within a single system, it is crucial to consider all the physics involved within the geomaterial system. A fully coupled thermo-hydromechanical model is developed. The model consists of a three-phase flow ... En savoir plus

[1]Imego AB, Gothenburg, Sweden
[2]Chalmers University of Technology, Gothenburg, Sweden

The objective of this work has been to realize a feasibility study of a cooling device for a SQUID sensor using liquid nitrogen flowing through micro channels. The design consists of an epoxy cylindrical vacuum vessel skewed by a silicon microchannel heat sink. The SQUID sensor is ... En savoir plus

Radio frequency Drying Based on Finite Element Method

Jiao Yang [1], Zhang Ruyi [1], PinZheng Wang [1], Yali Zhu [1], Shuang Li [1], Yixuan Chen [1], Jialing He [1], Feng Li [1],
[1] Shanghai Ocean University，ShangHai, China

Radio frequency (RF) drying is a novel drying technology. During the RF drying process, the internal and external temperature of the food material is elevated simultaneously when traditional heating method relies on heat transfer from the surface to the inside, which greatly improving ...
