[3] Safran, Paris, France

The Laser Metal Deposition process (LMD) is a rapid free form fabrication method which can be used to manufacture new near net shape metallic components, to repair used ones or to add functional parts on existing ones. This process is composed by multiple gas streams flowing inside a ... En savoir plus

A Numerical Investigation on Active Chilled Beams for Indoor Air Conditioning

G. Cammarata, and G. Petrone
Department of Industrial and Mechanical Engineering, University of Catania, Catania, Italy

In this study fluid-dynamical and thermal performance of active chilled beams is investigated by 2D and 3D modelling in COMSOL Multiphysics. Three different typologies of those air conditioning systems are considered. Results, obtained for typical range of variation of operational ... En savoir plus

Thermal Simulation of a Heat Pipe Tempered Injection Mould Tool

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 ... En savoir plus

Plasma Edge Simulations by Finite Elements using COMSOL

C. Hollenstein, and A. Howling
Ecole Polytechnique Fédérale de Lausanne, Switzerland

Finite elements using COMSOL Multiphysics have been used to simulate the edge plasma in a large area capacitively coupled RF reactor. In order to reduce numerical difficulties simplified reactor edge geometries have been used. First results show the importance of electrostatic double ... En savoir plus

Sensitivity Estimation of Permanent Magnet Flowmeter

[1]Fast Reactor Technology Group, Indira Gandhi Centre for Atomic Research, Kalpakkam, Tamil Nadu, India

Permanent Magnet Flowmeter (PMFM) is a non invasive device, which is used to measure the flow of electricallyconducting sodium in Fast Breeder Reactor Circuits. PMFM works on the principle of generation of motional EMF by magnetic forces exerted on the charges in a moving conductor. In ... En savoir plus

Effects of Thermal and Electro-Osmotic Flux on Grounding Electrodes

I. Ferreira de Rezende Costa¹, M. C. Barbosa¹, A. De Oliveira Costa Neto²
¹UFRJ, Rio de Janeiro, RJ, Brazil
²UFVJM, Teófilo Otoni, MG, Brazil

Electricity has become the main source of heat, power, and light used in the modern world. Much of the technological advances made over the last few decades are due to electrical energy. One of the essential components of the electrical system is the grounding network. The continuous ... En savoir plus

Multiphysics Simulation of a High Frequency Acoustic Microscope Lens

[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. ... En savoir plus

Structure of a Classical Vortex Ring

J. M. Russell [1],
[1] Florida Institute of Technology, Melbourne, FL, USA

This talk is for users of the COMSOL Multiphysics® software who, like the present author, are relative newcomers to numerical simulation but have a strong grounding in Hydrodynamics or related areas of Mathematical Physics.
