Simulation of Production Processes using the Multiphysics Approach: The Electrochemical Machining Process

R. van Tijum
Dr.
Advanced Technology Center, Philips Consumer Lifestyle, Drachten, The Netherlands

Redmer van Tijum studied Applied Physics at the University of Groningen. In 2006, he received his PhD title on ‘Interface and surface roughness of polymer metal laminates’ in the field of Material Science at the University of Groningen. After that he became research and development ... En savoir plus

Ultrafast Effects in 3D Metamaterials

N. Katte [1], P. Evans [2],
[1] Wilberforce University, Wilberforce, OH, USA
[2] Oak Ridge National Laboratory, Oak Ridge, TN, USA

The extraordinary electromagnetic response of nanostructured material, usually made up of a metallic structures distributed in within a dielectric matrix has attracted a lot of interest in recent years. These materials are technically called metamaterial (MM) since they possess ... En savoir plus

From Music to Non-Invasive Therapies via COMSOL Multiphysics® Models

E. Lacatus[1], G. C. Alecu[2], A. Tudor[2], M. A. Sopronyi[3]
[1]Polytechnic University of Bucharest, Bucharest, Romania
[2]Student-Polytechnic University of Bucharest, Bucharest, Romania
[3]INFLPR -National Institute for Laser Plasma and Radiation Physics, Bucharest, Romania

Vibration and music therapies are non-invasive treatments having effective results although their basics are still disputed. By the application of COMSOL Multiphysics® software for modeling and analysis, some of the nonlinear physical phenomena laying on these applications may be ... En savoir plus

Development of Micro/Nano Machines using COMSOL Multiphysics®

Shoji MARUO[1]

[1]Yokohama National University, Yokohama, Kanagawa, Japan

We have developed micro/nano machines such as optically driven micro/nano pumps and spiral-shaped piezoelectric vibration energy harvesters. COMSOL Multiphysics has been used for the design and development of the micro/nano machines. For example, optical force affected to a metallic ... En savoir plus

J. Speyrer [1], A. Maurer [1], D. Enfrun [1], R. Rozsnyo [2],
[1] Kejako SA, Plan les Ouates, Switzerland
[2] MNCM/HES-SO, Geneva, Switzerland

Kejako is developing a non-invasive solution for demanding presbyopia patients seeking to keep their quality of life through the compensation of visual accommodation decay. The company has already developed the first and proprietary 3D parametric model of the complete eye. The model ... En savoir plus

Nanoscale Heat Transfer using Phonon Boltzmann Transport Equation

S. Sihn[1,2], and A.K. Roy[2]

[1]Air Force Research Laboratory, Wright-Patterson Air Force Base, Dayton, Ohio, USA
[2]University of Dayton Research Institute, Dayton, Ohio, USA

COMSOL Multiphysics was used to solve a phonon Boltzmann transport equation (BTE) for nanoscale heat transport problems. One dimensional steady-state and transient BTE problems were successfully solved based on finite element and discrete ordinate methods for spatial and angular ... En savoir plus

Dynamic Deformation of Soft Particle in Dual-trap Optical Tweezers

Y. Sheng[1], S. Rancourt-Grenier[1], P. Bareil[1], P. Duval[1], M. Wei[2], A. Chiou[2], and J. Bai
[1]University Laval, Quebec, QC, Canada
[2]National Yang-Ming University, Taipei, Taiwan

A dual-trap optical tweezers is used for deforming the red blood cell (RBC) in suspension and studying its elasticity. The 3D deformation of the cells was computed with the elastic membrane theory. The calculated deformation can fit to experimental data resulting in cell’s elasticity ... En savoir plus

Modeling of Transport Phenomena in Gas Tungsten Arc Welding of Ni to 304 Stainless Steel

A. Bahrami[1], D. K. Aidun[1]
[1]MAE Department, Clarkson University, Potsdam, NY, USA

COMSOL Multiphysics® is used to simulate the transport phenomena in arc welding of Nickel to 304SS. Electric Currents (ec) and Magnetic Fields (mf) are used to solve for the Lorentz force which is one of the volume forces. Laminar Flow (spf) is used to simulate flow field. The Lorentz ...

University of Greenwich
London, UK

The aim of this article is to demonstrate the capability of the software for predicting free-surface motion and internal fluid flow in an electromagnetically levitated sample of liquid metal. Multiphysics solutions which demonstrate the usefulness of Comsol as a powerful MHD simulation ... En savoir plus

Metal MEMS Membrane Based Electric Field Sensor

E. Tahmasebian[1], C. Shafai[1], T. Chen[1]
[1]University of Manitoba, Winnipeg, MB, Canada

A MEMS based electrostatic field sensor is presented which uses capacitive interrogation of an electrostatic force deflected microstructure. The deflection of the sensor is calculated both by simulation and theoretical model and it has been shown that the results of the simulations have ... En savoir plus
