Electromagnetic Heating

Numerical 3D-FEM-simulation Made By COMSOL Multiphysics of a Microwave Assisted Cleaning System for a Diesel Sooty Particle Filter and its Experimental Validation

I. Imenokhoyev, A. Matthes, H. Gutte, and G. Walter
TU Bergakademie Freiberg
Freiberg, Germany

By means of a numerical 3D-FEM-simulation, some alternatives for the arrangement of the waveguide supplying the microwave energy to a cylindrical ceramic filter are investigated. The different alternatives are compared concerning a homogenous distribution of the electromagnetic field and ... En savoir plus

Multiphysics Design of ESS-Bilbao Linac Accelerating Cavities Using COMSOL

J. L. Munoz, and I. Rodriguez
ESS-Bilbao
Bilbao, Spain

A proton linac drives particles using the electric field of a high power RF standing wave in a resonant cavity. The design of these cavities involve several aspects of multiphysics simulation, that have been accomplished using COMSOL. The first step consist on the geometric optimization ... En savoir plus

Analytical and Experimental Validation of Electromagnetic Simulations Using COMSOL®, re Inductance, Induction Heating and Magnetic Fields

M. W. Kennedy, S. Akhtar, J. A. Bakken, and R. E. Aune
Norwegian University of Science and Technology (NTNU)
Trondheim, Norway

This paper presents a snap shot of experimental work, which has been conducted at NTNU on billet heating with induction coils. A significant volume of experimental data have been collected for coils running with up to 0.2T: high accuracy Hall probe readings (+/-1%), metal ... En savoir plus

Transient Analysis of the Triggering Behaviour of Safety Fuses

F. Loos, and H.-D. Ließ
Universität der Bundeswehr München
München, Germany

The purpose of this work is to investigate the triggering behaviour of safety fuses for mobile on board supply systems. The influence of different materials and shapes of the fuses on the triggering behaviour are analyzed. Furthermore, the simulation results obtained by the use of COMSOL ... En savoir plus

Numerical Analysis of the 3-omega-method

M. Feuchter, and M. Kamlah
Karlsruhe Institute of Technology (KIT)
Institute for Applied Materials
Karlsruhe, Germany

Determining the thermal conductivity of condensed matter attracted much attention in past years. While several techniques exist to measure the thermal conductivity of solids or thin films, the 3-omega-method is one of the most well-established due to its high accuracy. First, COMSOL ...

Modeling of Susceptor Assisted Microwave Heating in Domestic Ovens

K. Pitchai[1], S. Birla[2], J. Diamond Raj[3], J. Subbiah[2], and D. Jones[2]
[1]Dept. of Food Science and Technology, University of Nebraska, Lincoln, NE
[2]Dept. of Biological Systems Engineering, University of Nebraska, Lincoln, NE
[3]Indian Institute of Crop Processing Technology, Thanjavur, Tamil Nadu, India

Susceptors are very thin metallic microwave absorbing films used in microwaveable food packaging. They tend to heat up very rapidly during microwave heating and this effect helps to overcome two major issues faced in domestic microwave ovens; 1) Non-uniform heating and 2) lack of ...

Simulation of Quench Propagation in a Double-Helix Superconducting Magnet with COMSOL Multiphysics

P. Masson
Advanced Magnet Lab
Palm Bay, FL

The paper presents the numerical analysis of quench propagation in a DH magnet wound with a commercially available MgB2 wire in a fiber-glass composite matrix and operating at 20 K. The quench is induced by a small heater located on the first layer of the magnet close to the peak field ... En savoir plus

Modeling of Microwave Heating of a Rotating Object in a Domestic Oven in COMSOL Multiphysics

J. Raj[1], S. Birla[2], K. Pitchai[3], J. Subbiah[2], and D. Jones[2]
[1]Indian Institute of Crop Processing Technology, Thanjavur, Tamil Nadu, India
[2]Dept. of Biological Systems Engineering, University of Nebraska Lincoln, Lincoln, NE
[3]Dept. of Food-Science, University of Nebraska Lincoln, Lincoln, NE

Domestic microwave ovens are notorious for their uneven heating of food materials. This is caused by a varying electromagnetic field whose variation is caused by a number of factors dependent on the oven and the food parameters. Experimental validation of heating would therefore give ... En savoir plus

Analysis of Microwave Radiation for Heating

J. Crompton, S. Yushanov, L. Gritter, and K. Koppenhoefer
AltaSim Technologies, LLC.
Columbus, OH

Microwave heating is an important process for many commercial, industrial and household applications. In microwave heating applications, the energy is introduced directly into the volume of the material. As a consequence the quality of the process is highly dependent on the uniformity of ...
