Thermal Analysis of High Power LEDs

C-C. Hsu
Kao Yuan University, Taiwan

Assistant Professor Chin-Chuan Hsu received his Master degree (1991) in Materials Science and Engineering from National Cheng Kung University, Tainan, Taiwan. In 1995 he received the Ph.D. degree in Materials Science and Engineering from National Taiwan University, Taipei, Taiwan. From ... En savoir plus

Modeling of charged droplet dynamics in an Electric Field using COMSOL Multiphysics®

M. STURMA¹, P.NAMY², V. BRUYERE², B.BARBET¹
¹MARKEM-IMAJE Industries, Bourg les Valence, France
²SIMTEC, Grenoble, France

In the field of coding and industrial marking areas, CIJ technology is based on high speed emission of ink drops (20 m/s) which are directed onto a moving printing medium. The printing quality depends, on one hand, on drops position on the media determined by the drop charge and the ... En savoir plus

3D Hydrodynamic and Mass Transport Simulations of Ocular Drug Delivery

Loke Chai Yee [1],
[1] Monash University Malaysia, Malaysia

The present study is motivated by the recent concerns raised over the existence of segmental outflow of the aqueous humour (AH) and its implications on ocular drug delivery. A 3D model of the human eye is developed, where hydrodynamic and mass transport analyses, specifically after eye ... En savoir plus

Analysis of Electromagnetic Fields in Urban Environments

J. Crompton [1], L. Gritter [1], S. Yushanov [1], K. Koppenhoefer [1],
[1] AltaSim Technologies, Columbus, OH, USA

Electromagnetic fields are pervasive in today’s urban environment and under certain circumstances exposure has led to safety hazards that have been reported to cause personal injury. The United States Department of Labor has reported multiple cases of electrical shock on construction ... En savoir plus

Electrochemistry Modeling of a Smartphone Based Electrochemiluminescence Sensor

H. Kwon¹, E. C. Rivera²
¹Andrews University, Berrien Springs, MI, USA
²Laboratório Nacional de Ciência e tecnologia do Bioetanol, Campinas, SP, Brazil

An electrochemiluminescence (ECL) sensor was developed in a smartphone-based platform using a disposable disk-shaped carbon electrode. A time-varying square waveform potential was applied to the working electrode, and the current and ECL intensity data were measured. The applied ... En savoir plus

Virtual Design of a Four-Bed Molecular Sieve for Exploration

T. Giesy [1], R. Coker [1], J. Knox [1], B. O'Connor [1],
[1] NASA Marshall Space Flight Center, Huntsville, AL, USA

Aboard the International Space Station, carbon dioxide is removed from the atmosphere using a four-bed adsorptive separation process, referred to generally as a 4-Bed Molecular Sieve (4BMS). Experience with the current 4BMS design in space has led to a list of areas for improvement for a ... En savoir plus

Improving the Sensoring of PEM Fuel Cell by Numerical Techniques

S. Skoda[1], E. Robalinho[2], E. F. Cunha[1], M. Linardi[1]
[1]Instituto de Pesquisas Energéticas e Nucleares - IPEN/CNEN-SP, São Paulo, SP, Brazil
[2]Universidade Nove de Julho - UNINOVE, São Paulo, SP, Brazil

The use of numerical techniques in PEM fuel cell sensoring represents an advantage of project engineering, reducing the costs and accelerating the manufacturing of prototypes. In this work some numerical responses are shown, relating to numerical sensoring of water and oxygen mole ... En savoir plus

Implementation of Optimization Method for Inverse Heat Conduction and for Sensor Position Correction

R. Dalshad¹, N. Perakis², M. Pfitzner¹
¹Institute for Thermodynamics, Bundeswehr University Munich, Germany
²Chair of Turbomachinery and Flight Propulsion, Germany

In this work the implementation of an optimization method [1, 2] for inverse heat transfer and for the sensor position correction, such as thermocouples, in COMSOL Multiphysics®and LiveLink™ for MATLAB® is presented. The inverse method is used to determine the unknown boundary condition ... En savoir plus

Implementation of an Optimization Method for Inverse Heat Conduction and Sensor Position Correction

R. Dalshad¹, N. Perakis², M. Pfitzner¹, O. J. Haidn²
¹Institute for Thermodynamics, Bundeswehr University Munich, 85577 Neubiberg, Germany
²Chair of Turbomachinery and Flight Propulsion, Technical University of Munich, 85748 Garching, Germany

Heat conduction problems can be divided into direct and inverse problems. In direct problems, the thermal boundary condition (heat flux or temperature) is given and its effect is calculated, while for inverse problems the boundary condition is determined based on its effect. For some ... En savoir plus

Modeling a Resonant Near-Field Scanning Microwave Microscope (RNSMM) Probe

N. Smith[1], K. Lees[1], A. Gregory[1], R. Clarke[1]
[1]The National Physical Laboratory, Teddington, Middlesex, UK

The current drive to go beyond the state of the art in novel near field scanning microwave microscope (NSMM) metrology at the micro scale, to make them capable of traceable measurements on functional materials, has led to the development of a finite element model of the probe of a ...
