A COMSOL Model of Damage Evolution Due to High Energy Laser Irradiation of Partially Absorptive Materials

P. Joyce[1], J. Radice[1], A. Tresansky[1], J. Watkins[1]
[1]United States Naval Academy, Annapolis, MD, USA

In this paper we present a transient numerical model of the heat transfer and thermochemical damage evolution in an IR translucent material using COMSOL Multiphysics. The model is evaluated using literature supplied and experimentally determined material properties for carbon black laden ... En savoir plus

Analysis of Fluid Pumping with a Throttle Type Piezoelectric Micro Pump

B. Pe?ar[1], D. Križaj[1], D. Vrta?nik[1], D. Resnik[1], U. Aljan?i?[1], M. Možek[1], T. Dolžan[1], A. Slavko[1]
[1]Faculty of Electrical Engineering, UNI of Ljubljana, Ljubljana, Slovenia

Operation of a modified type microthrottle (MT) pump is analyzed by numerical simulation. Conventional MT pumps have disk type piezoelectric membranes while the analyzed type has a membrane of a rectangular shape. This could be advantageous in case the pump is stacked into an array for ... En savoir plus

Simulation and Experimental Validation of the Core Temperature Distribution of a Three-Phase Transformer

R. Barroso[1]
[1]Universidade Federal do Ceará, Fortaleza, Ceará, Brazil

This paper presents an application of COMSOL Multiphysics® software in the study of the temperature distribution of a 5kVA three-phase air-cooled transformer. A 3D, steady state model was utilized on the simulations. The interface with the surrounding air was modeled by Newton's Law of ... En savoir plus

Simulation of a Buckled Cantilever Plate with Thermal Bimorph Actuators

A. Arevalo [1], D. Conchouso [1], D. Castro [1], M. Diaz [2], I. G. Foulds [3],
[1] CEMSE Division, King Abdullah University of Science and Technology, Thuwal, Saudi Arabia
[2] Physical Sciences and Engineering Division, King Abdullah University of Science and Technology, Thuwal, Saudi Arabia
[3] University of British Columbia, Vancouver, BC, Canada

INTRODUCTION: Micro Electro Mechanical Systems (MEMS) are fabricated with an in-plane fabrication technology. Out-of-plane structures can be designed to be assembled to provide thermal and electrical isolation from the substrate [1 -3]. These isolations can potentially improve the ... En savoir plus

COMSOL Assistance for the Modeling of Cellular Microsystems

J. Berthier
CEA-LETI-Minatec
Grenoble, France

The developments of microsystems for biotechnology have been fast in the last few years, and no sign of slowing down is observed. It has begun with lab-on-chip for genomics, especially for the recognition of DNA sequences, followed by protein reactors and immunoassays, and today the ... En savoir plus

Lithography-Patterning-Fidelity-Aware Electron-Optical System Design Optimization by Using COMSOL Multiphysics with MATLAB®

Sheng-Yung Chen [1], Kuen-Yu Tsai [1]
[1]Dept. of Electrical Engineering, National Taiwan University, Taipei, Taiwan

Electron-optical system (EOS) design for lithography provides the inherent advantage of higher resolution and maskless operation relative to optical technology. The use of multiple electron beams yields higher throughput, albeit with greater complexity in focusing, relative to the single ... En savoir plus

On The Purification Of Waste Waters Using Multi-Bore Filters: Simulation Of A Long-Term Filtration Stage

I. Borsi
Dipartimento di Matematica U. Dini, Universita' di Firenze, Italy

We present the progress of the simulation activity we are carrying out within the PURIFAST LIFE+ project. We first present the model we formulated to describe the macroscopic effects of the filtration process taking place in a multi-bore filter, focusing on the fouling phenomenon. In ... En savoir plus

[2]Gadda Industrie, Ivrea, Italy
[3]Laboratori Archa, Pisa, Italy

This paper deals with an integrated numerical and experimental analysis work aiming at the investigation of the thermal distribution inside an industrial furnace built for metal materials treatments. The main goal of the research is to find the geometrical and/or functional parameters ... En savoir plus

Heat Drain Device on Ultrasound Imaging Probe

G. Vigna[1], L. Spicci[1]
[1]Esaote SPA, Florence, Italy

Self-heating is a problem to consider for Ultrasound Imaging probes. Since the probe is in contact with the skin, it’s necessary to find a solution to lower the front face temperature in order to avoid patient discomfort, even at the most demanding operating condition. One solution ... En savoir plus

Modelling of a 5 Cell Intermediate Temperature Polymer Electrolyte Fuel Cell (IT-PEFC) Stack: Analysis of Flow Configuration and Heat Transfer

A.S. Chandan[1], A. Mossadegh Pour[2], R. Steinberger-Wilckens[2]
[1]Centre for Hydrogen and Fuel Cell Research, University of Birmingham, Birmingham, United Kingdom
[2]University of Birmingham, Birmingham, United Kingdom

Polymer Electrolyte Fuel Cells (PEFCs) are a key technology in the advancement of society towards a low carbon future, in particular for use within the automotive sector. PEFCs are advantageous due to their low operating temperature (60-80 deg.C), quick start up times and responsiveness ... En savoir plus
