Numerical Solution of Nonlinear PDEs Exhibiting Soft Bifurcations

A. Boulbitch [1],
[1] IEE S.A. Luxembourg

This talk communicates a pseudo-dynamic approach to solve nonlinear stationary equations exhibiting soft bifurcations. The procedure consists in passing from the stationary partial differential equation - to an artificially-built pseudo-time dependent one. We construct the latter in ... Read More

Heat and Moisture Transport in Wooden Bearings of Monumental Buildings

H. Schellen [1], M. Spierings [2], J. van Schijndel [3],
[1] Eindhoven University of Technology, The Netherlands
[2] DPA Cauberg-Huygen, The Netherlands
[3] ASML, The Netherlands

Currently insulation has been and will in future be applied to many buildings. This proves to be a challenge for monumental or old buildings. Mostly insulation has to be applied at the interior side of a building. That is why hygro-thermal bridges are inevitable. A wooden beam end beared ... Read More

Simulation of Acoustically Excited Membrane Waves on an Eye

J. Mäkinen [1], D. Veira Canle [1], T. Ylitalo [1], R. Montonen [1], H. Malinen [1], S. Bäckroos [1], P. Ihalainen [1], E. Lampsijärvi [1], J. Heikkilä [1], T. Paulin [1], A. Salmi [1], A. Kontiola [1], I. Kassamakov [1], E. Hæggström [1],
[1] Department of Physics, Division of Materials Physics, University of Helsinki, Helsinki, Finland

High intraocular pressure (IOP) is a risk factor for glaucoma, a condition that can cause blindness. Conventional ways of measuring IOP either require contact or can be uncomfortable for the patient. We have developed a method to measure IOP from the propagation time of a wave on the ... Read More

Design and Simulation of Cyclotron Magnet Using COMSOL Multiphysics®

F. Alrumayan [1], A. Hendy [1], H. Kassim [2],
[1] King Faisal Specialist Hospital and Research Centre, Saudia Arabia
[2] King Saud University, Saudia Arabia

Medical accelerators, in particular Cyclotrons, are used to accelerate charged particles to tens of Mega electron Volts (MeV) of energies. These high energy particles then used to produce isotopes for medical application such the system located at king Faisal Specialist Hospital and ... Read More

Multiphysics Simulation of a High Frequency Acoustic Microscope Lens

O. Tommiska [1], J. Mäkinen [1], J. Hyvönen [1], A. Meriläinen [1], A. Salmi [1], E. Hæggström [1],
[1] Department of Physics, Division of Materials Physics, University of Helsinki, Helsinki, Finland

High frequency ultrasound (100-1000 MHz) has been used in microscopy since the 1970s. The main imaging component, the acoustic lens, is commercially available. The resolution, working distance, and focal length depend on the structure of a lens, which is unique for each produced lens. ... Read More

Using COMSOL Multiphysics® to Simulate Heat Exchanger Fouling by Heterogeneous Barite Crystallisation

F. Cazenave [1], F. Couture [1], P. Bernada [1], J-P. Serin [1],
[1] Univ Pau & Pays Adour/ E2S UPPA, Laboratoire de Thermique, Energetique et Procedes- IPRA, EA1932, Pau, France

Heat exchanger fouling is one of the biggest problems of industry. The induced loss of efficiency leads to oversizing and over-costs. In order to eliminate the fouling layer, maintenance operations are required. This study focus on the physicochemical and hydrodynamic mechanisms ... Read More

Inertial Manipulation of Bubbles in Rectangular Microfluidic Channels

P. Hadikhani [1], S. Mohammad H. Hashemi [1], G.Balestra [2], L. Zhu [3], M. A. Modestino [4], F. Gallaire [2], D. Psaltis [1],

[3] Department of Mechanical and Aerospace Engineering, Princeton University, US
[4] Department of Chemical and Biomolecular Engineering, Tandon School of Engineering, New York University, US

Bubbles trajectories in microchannel laminar flow can be controlled with fluidic forces. This effect finds applications in the field of electrochemical engineering. In this study, we investigate the bubble motion at moderate Reynolds number (1 Read More

COMSOL® Simulation for Scanning Microwave Microscopic Experiments

T. Le Quang [1], D. Vasyukov [1], A. Buchter [1], J. Hoffmann [1], M. Zeier [1],
[1] Eidgenössisches Institut für Metrologie (METAS), Switzerland

In the EMPIR project ADVENT the Scanning Microwave Microscopy (SMM) is investigated. The SMM is a still rather novel member of the family of scanning probe microscope. It has attracted a lot of attention recently, because this instrument can be used to characterize various electrical ... Read More

A Model of Concrete Carbonation Using COMSOL Multiphysics®

B. Chine' [1], R. Cuevas [2], R. Jimenez [1], A. Rodríguez [1],
[1] Costa Rica Institute of Technology, School of Materials Science and Engineering, Cartago, Costa Rica
[2] Costa Rica Institute of Technology, School of Construction Engineering, Cartago, Costa Rica

In the construction sector the concrete and the steel bars represent still the key components, although they are very vulnerable by the atmospheric agents, as in the case of their degradation caused by corrosion. The study of the concrete carbonation, due to the CO2 which permeates the ... Read More
