Numerical Modeling of Heat and Mass Transfer in Porous Materials During Drying and Shrinkage

D. Lelièvre[1], P. Glouannec[1]
[1]Université de Bretagne-Sud, Lorient, France

Drying is an essential step in many manufacturing processes, for it will have an important impact on the product quality. This is why many numerical models have been realized over decades, in order to predict the hygrothermal behavior of porous media during the drying process. In this ... En savoir plus

Passive Microsensor Based on LC Resonators for Substance Identification

D.A. Sanz Becerra[1], E.A. Unigarro Calpa[1], J. Osma[1], F. Segura[1]
[1]Universidad de los Andes, Bogotá, Colombia

A scheme for inductive wireless powering and readout of passive LC sensor is presented. The sensor’s inductor is designed as a planar square coil and is used as the power receiving component. The capacitor is connected directly to the inductor and it was designed as an interdigital ... En savoir plus

Making Cartograms and Using them for Data Acquisition

P. Mercure[1], and R. Haley[2]
[1]The Dow Chemical Company, Midland, MI
[2]ATM Research, Midland, MI

We demonstrate cartogram construction, where a geographical map is distorted to represent some measure, for example population, while trying to keep the shape of regions recognizable. We then apply this cartogram construction technique to optimize thermocouple locations. A heat ... En savoir plus

Numerical modelling of the damage potential of climate variations to a historic wooden cabinet

Z. Huijbregts, H. Schellen, and J. van Schijndel
Department of the Built Environment
Eindhoven University of Technology
Eindhoven, The Netherlands

The two wooden cabinets of Jan van Mekeren that are located in Amerongen Castle show comparable wood damage; in particular large cracks in the cabinet doors are clearly noticeable. It is assumed that these cracks were caused by bad indoor climate conditions in the castle. Combined ... En savoir plus

Thermo-Mechanical Analysis of Composite Material Exposed to Fire

A. Davidy[1]
[1]IMI, Ramat Hasharon, Israel

This paper presents thermo-mechanical models for predicting the strength of polymer laminates loaded in tension or compression exposed to one-sided radiant heating by fire. The first part is the fire simulation where the FDS model is utilized. The FDS model generates a solution of ... En savoir plus

Optimal Heat Sink Fin and Cold Lid Heights for Liquid Immersed Servers

A. Almaneea[1], J. Summers[1], H. Thompson[1], N. Kapur[1]
[1]University of Leeds, Leeds, United Kingdom

The system in this study is a closed server filled with Novac dielectric cooling liquid. The aim of this study is to find out the optimum value of the fin height and the cold lid height in order to reduce CPU temperature. A mesh accuracy investigation was conducted. The model set up in ... En savoir plus

Aerodynamic Analysis of a Ski Jumper: a CFD Approach

R. Latchman [1], A. Pooransingh [1],
[1] The University of the West Indies, St. Augustine, Trinidad and Tobago

At the 2006 Winter Olympics, the jump length difference between first and second place was only 5cm. This illustrates why ski jumpers are constantly tinkering with their posture in order to gain even the smallest of advantages. Experiments such as those shown in Figures 1 and 2 (b), ...

Implementation of a Porous Media Model for Simulating Pressure Development in Heated Concrete

B. Weber [1], D. Dauti [2], S. Dal Pont [2],
[1] Empa, Swiss Federal Laboratories for Materials Science and Technology, Dübendorf, Switzerland
[2] Laboratoire 3SR, University Grenoble Alpes, Grenoble, France

When concrete is subjected to high temperature, capillary water evaporates and chemically bound water is released due to dehydration. This results in an increase of pore pressure, which is believed to be one of the mechanisms leading to spalling. Spalling of concrete is of high concern ... En savoir plus

Performance Evaluation of the 19th Century Clipper Ship Cutty Sark: A Comparative Study

C. Tonry[1], M. Patel[1], C. Bailey[1], W. Davies[1], J. Harrap[1], E. Kentley[1], P. Mason[1]
[1]University of Greenwich, London, UK

The Cutty Sark, built in 1869 in Dumbarton, is the last intact composite tea clipper ship [1]. One of the last tea clippers built she took part in the tea races back from China. These races caught the public imagination of the day and were widely reported in newspapers [2]. They ... En savoir plus

Polyimide Thermal Micro Actuator

A. Arevalo[1], I. G. Foulds[2]
[1]Computer, Electrical and Mathematical Sciences and Engineering Division (CEMSE), King Abdullah University of Science and Technology, Thuwal, Saudi Arabia
[2]School of Engineering, Okanagan Campus, The University of British Columbia, Vancouver, BC, Canada

Joule heating is simulated in COMSOL Multiphysics® software for the electro-thermal micro actuator. The aim is to choose the optimal design parameters to get the largest possible in-plane displacement. The comparison between the different possible configurations will reveal the optimal ...
