[1]Advanced Study Centre, National Institute for Aerospace Research “Elie Carafoli”, Bucharest, Romania
[2]Technical University of Civil Engineering Bucharest, Bucharest, Romania

Laser anemometers based on application of Doppler Effect have been developed and are used in-flight, on aircrafts for measurement of air flow parameters, mainly its speed versus the airplane. The air speed measurements are vital for safe flights. The main basic idea of Doppler techniques ... Mehr lesen

This paper presents and discusses HazRes’ research and results associated with the simulation and modelling of hydrogen release and dispersion events in indoor enclosed environments, using COMSOL Multiphysics. HazRes has developed a gas dispersion model in COMSOL, which takes into ... Mehr lesen

Simulation of Sample Inhomogeneity in Microwave Impedance Microscopy

T. S. Jones [1], C. R. Pérez [1], J. J. Santiago-Avilés [1],
[1] University of Pennsylvania, Philadelphia, PA, USA

Microwave impedance microscopy (MIM) is a novel mode of atomic force microscopy that can measure topography and local electrical impedance simultaneously and with nanometer spatial resolution [1]. This technique is typically used qualitatively, identifying defects in nanodevices or ... Mehr lesen

Development of a Thermal Model Using COMSOL Multiphysics® Software

A. Oukaira [1], A. Lakhssassi [1],
[1] Department of Computer Science, Université du Québec en Outaouais à Hull, Gatineau, QC, Canada

The Purpose of this paper is to develop a thermal model using COMSOL Multiphysics® software that aims to get an idea of the heat flow around the ASIC, as well as to address the thermal issues for integrated circuits at the tongue board. However, we need sources of heat simulations to map ... Mehr lesen

Modeling of Transport Phenomena in Metal Foaming

[1]Laboratorio MUSP Piacenza, Italy; ITCR, Esc. Ciencia e Ing. Materiales, Cartago, Costa Rica
[2]Laboratorio MUSP, Piacenza, Italy; Politecnico di Milano, Dip. Meccanica, Milano, Italy

Metal foams are interesting materials with many potential applications in engineering. Foamed metals or alloys include gas voids in the material structure with the real possibility to modify ad hoc their physical properties. Following our previous efforts aimed to simulate and study the ... Mehr lesen

SD Numerical Simulation Technique for Hydrodynamic Flow Gas-Solids Mixing

I. Mantilla[1], S. De Vicente[2]
[1]National University of Engineering, Lima, Perú
[2]Polytechnic University of Madrid, Madrid, Spain

We formulate a new mathematical model of gas-solids mixing hydrodynamic flow [1] in a combustion chamber with a fluid bed system used in the combustion of mineral coal waste. This model in study is called Model Gas-Solids Mixing and it is constructed by averaging the conservation ... Mehr lesen

Use of FEM in the Design of an HTS Insert Coil for a High Field NMR Magnet

E. Bosque[1]
[1]Applied Superconductivity Center, National High Magnetic Field Laboratory, Tallahassee, FL, USA

High temperature superconductors (HTS) allow larger current densities through coil wound electromagnets, which produce higher magnetic fields. A high field HTS insert demonstration magnet is being built with high field homogeneity (~1 ppm) for application in nuclear magnetic resonance ... Mehr lesen

Solid-Liquid Phase Change Simulation Applied to a Cylindrical Latent Heat Energy Storage System

D. Groulx[1], and W. Ogoh[1]

[1]Mechanical Engineering Department, Dalhousie University, Halifax, Nova Scotia, Canada

One way of storing thermal energy is through the use of latent heat energy storage systems. One such system, composed of a cylindrical container filled with paraffin wax, through which a copper pipe carrying hot water is inserted, is presented in this paper. It is shown that the physical ... Mehr lesen

Glass Plates Noise Transmission Suppression by Means of Distributed Piezoelectric Composite Actuators Shunted by an Active Circuit

[1]Research Centre for Special Optics and Optoelectronic Systems (TOPTEC), Institute of Plasma Physics, Academy of Sciences of the Czech Republic, Turnov, Czech Republic
[2]Institute of Mechatronics and Computer Engineering, Technical University of Liberec, Liberec, Czech Republic

Glass windows represent a virtual sound source for buildings interior. It is very easy to make them vibrate by action of incident acoustic pressure wave. Therefore, non-negligible part of the wave is transmitted through the window. We propose and simulate a method based on the change of ... Mehr lesen
