Design & Simulation of Various Shapes of Cantilever Beam for Piezoelectric Power Generator

P. Graak [1], S. Kaur [1], A. Gupta [1], P. Chhabra [1], D. Kumar [1], A. Shetty [2]
[1] Kurukshetra University, Kurukshetra, Haryana, India
[2] Indian Institute of Science, Bengaluru, Karnataka, India

The ambient vibrations can be of great promise for harvesting energy initially at small scale to use for micro and nano scale devices. Such vibrations converted to electrical energy by piezoelectric transducer due to their major significance. Various research journals have introduced the ... En savoir plus

Simulation of an ECT Sensor to Inspect the Reinforcement of Concrete Structures

N. P. de Alcantara Jr. [1], L. Gonçalves Jr. [1],
[1] São Paulo State University - Unesp, Bauru, SP, Brazil

The paper describes the use of COMSOL Multiphysics to simulate an ECT (Eddy Current Testing) sensor, designed to inspect the elements of the reinforcement of concrete structures. The paper describes the steps for the COMSOL simulation, and analyze the results for three configurations ... En savoir plus

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 ... En savoir plus

Modeling of Transport Phenomena in Metal Foaming

B. Chinè[1], M. Monno[2]
[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 ... En savoir plus

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 ... En savoir plus

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 ... En savoir plus

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

K. Novakova[1][2], P. Mokry[2]
[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 ... En savoir plus

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 ... En savoir plus

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 ... En savoir plus
