Enhanced Surface Plasmon Polariton Propagation Induced by Active Dielectrics

M. Mattheakis[1], C. Athanasopoulos[1], G. P. Tsironis[1]
[1]University of Crete, Heraklion, Greece

We present numerical simulations for the propagation of surface plasmon polaritons in a dielectric-metal-dielectric waveguide using COMSOL Multiphysics® software. We show that the use of an active dielectric with gain that compensates metal absorption losses enhances substantially ... En savoir plus

Numerical Optimization of Heating for High-Speed Rotating Cup by Means of Multiphysics Modeling and its Experimental Verification

K. Kyrgyzbaev[1], M. Willert-Porada[1], M. Terock[1]
[1]University of Bayreuth, Chair of Materials Processing, Bayreuth, Germany

The physics of rotating cups and disks is an important research subject in many areas of engineering. The rotating cup/disk has been employed in many industrial applications such as spin-coating of phosphor on television screens or photoresist films on silicon wafer, concentrating ... En savoir plus

Virtual Prototype Evolution by COMSOL Multiphysics® of a Continuous Flow Animal By-Products ABP Ohmic Sterilization Unit

R. Heslop[1]
[1]C-Tech Innovation Ltd., Capenhurst, Cheshire, UK

Ohmic heating (Joule heating) is a volumetric heating technology which can effectively process almost any pumpable fluid with extremely high energy efficiency (>95%). This is particularly useful for very thick fluids, those that burn on to hot surfaces and those with high solids content ... En savoir plus

Virtual Prototype of a Dielectric Window for High-Power Microwave Tubes

A. Leggieri[1], D. Passi[1], F. di Paolo[1]
[1]Dipartimento di Ingegneria Elettronica, Università degli Studi di Roma Tor Vergata, Rome, Italy

This paper describes the Virtual Prototype of a Dielectric Window or High Power Microwave Vacuum Tubes and Linear Accelerators. Design formulas are provided and Computer Aided Design techniques based on COMSOL Multiphysics® software are proposed. The virtual prototype considers the ... En savoir plus

3D Acoustic Streaming Field in High-Intensity Discharge Lamps

B. Baumann[1], J. Schwieger[1], M. Wolff[1], F. Manders[2], J. Suijker[2]
[1]Hamburg University of Applied Sciences, Hamburg, Germany
[2]Philips Lighting, Turnhout, Belgium

High-intensity discharge lamps will in the foreseeable future be important light sources despite a growing market share of LEDs. Cost and energy efficient high frequency (300 kHz) operation is hampered by the excitation of acoustic resonances inside the arc tube, which results in low ... En savoir plus

Modeling and Simulation of Membrane Contactor Employed to Strip CO2 from Rich Solvents via COMSOL Multiphysics®

N. Ghasem[1], M. Al-Marzouqi[1], N. A. Rahim[1]
[1]United Arab Emirates University, Al-Ain, United Arab Emirates

A mathematical model is developed for the stripping of CO2 from rich solvent. The rich solvent (aqueous NaOH) is used in CO2 absorption from natural gas through gas-liquid hollow fiber membrane contactor. The polyvinylidene fluoride (PVDF) hollow fiber membrane was fabricated via ... En savoir plus

3D Multiphysics Modeling of Bulk High-Temperature Superconductors for Use as Trapped Field Magnets

M. Ainslie[1], J. Zou[1], D. Hu[1], D. Cardwell[1]
[1]Department of Engineering, University of Cambridge, Cambridge, UK

The authors are currently investigating the use of bulk high temperature superconductors as trapped field magnets (TFMs) in order to increase the electrical and magnetic loading of an axial gap, trapped flux-type superconducting electric machine. In electric machines, the use of ... En savoir plus

Evaluation of the Shutdown Time of Subsea Pipeline for Oil Transportation

D. Maciel[1], N. Bouchonneau[1]
[1]Universidade Federal de Pernambuco, Recife, Pernambuco, Brazil

The maintenance plan or rush-to-repair of a subsea pipeline for oil transport may result in the shutdown of the line, in other words, may stop the flow of fluid. During the shutdown, the temperature of the oil tends to decrease continuously, and the heavy molecules tend to crystallize ... En savoir plus

Evolution of the Geochemical Background of an HLW Cell in the Callovo-Oxfordian Formation

O. Silva[1], M. Pekala[1], D. Garcia[1], J. Molinero[1], A. Nardi[1], M. Grive[1], B. Cochepin[2]
[1]Amphos 21 Consulting, Barcelona, Spain
[2]Agence Nationale pour la Gestion des Dechéts Radioactifs, Châtenay-Malabry Cedex, France

The French National Waste Management Agency (Andra) envisages the safe disposal of High-Level Waste Intermediate-Level Long-Lived Waste through deep geological storage (multibarrier). Waste storage is based on the Callovo-Oxfordian formation (CallOx). It has been updated a reactive ... En savoir plus

iCP 1.0: Stable Release Version of the Interface COMSOL-PHREEQC

A. Nardi[1], L. M. deVries[1], A. Sainz[1], J. Molinero[1]
[1]Amphos 21 Consulting, Barcelona, Spain

iCP (Nardi et al, 2014) is a software that couples two standalone simulation programs: COMSOL Multiphysics® and PHREEQC (Parkhurst & Appelo, 2013). The tool is ideal for applying multiphysics and geochemistry in Earth Sciences. Flexibility of the two coupled codes result in an ... En savoir plus
