Numerical Simulation of a Rotary Desiccant Wheel

G. Diglio[1], P. Bareschino[1], G. Angrisani[1], M. Sasso[1], F. Pepe[1]
[1]Università degli Studi del Sannio, Benevento, Italy

The core unit of desiccant cooling systems is a dehumidifying device, in most cases a wheel made of inert material coated with an adsorbent (silica gel in the present work). Two sections can be identified: air to be dehumidified was passed through the process section, while in the ... En savoir plus

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

Numerical Modelling Of Sound Absorptive Properties Of Double-Porosity Granular Materials

R. Venegas, and O. Umnova
Acoustics Research Centre, University of Salford, Salford, United Kingdom

Granular materials have been conventionally used for acoustic treatment due to their sound absorptive and sound insulating characteristics. An emerging field is the study of acoustical properties of multi-scale porous materials. An example of these is a double-porosity granular material ... En savoir plus

Thermal Analysis of a Piezo-Disk Ultrasound Probe

L. Spicci[1], M. Cati[1]
[1]Esaote, Firenze, Italy

Ultrasound imaging probes are widely used for several types of diagnosis applications. In the present work we focus our attention on a disk-type probe, which is widely used in CW and PW operating conditions. In particular we present a 2D-axial symmetry FEM for the probe, capable to ...

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

Phase Field Modeling of Helium Precipitate Networks on Solid-state Interfaces

D. Yuryev[1], M. Demkowicz [1]
[1]Massachusetts Institute of Technology, Cambridge, MA, USA

We describe simulations performed in COMSOL Multiphysics® of the precipitation of helium (He) on solid-state interfaces. The non-uniform precipitation of He at certain interfaces is a result of a heterogeneous energy distribution in the interface plane: He wets high interface energy ( ... En savoir plus
