Thermal Adversity in Solid-State Lighting

T. Dreeben[1]
[1]OSRAM SYLVANIA, Beverly, MA, USA

COMSOL Multiphysics is used to simulate natural convection and its impact on peak operating temperatures of solid-sate lighting in thermally adverse conditions. PDE modes in the general form are used in conjunction with a thin-surface conduction formulation in the weak form. COMSOL is ... Read More

On A Particle Tracking Technique To Predict Disinfection In Drinking Water Treatment Systems

B.A. Wols[1,2], J.A.M.H. Hofman[1,2], W.S.J. Uijttewaal[2], and J.C. van Dijk[2]
[1]KWR Watercycle Research Institute, Nieuwegein, The Netherlands
[2]Delft University of Technology, Niewegein, The Netherlands

Disinfection of drinking water is required to prevent the outbreak of water-borne diseases. Different treatment steps are available to disinfect the water, such as chlorination, ozonation or UV irradiation. The hydrodynamics of these processes play an important role in their performance. ... Read More

Simulation of PCM Melting Process in a Rectangular Enclosure Differentially Heated

G. Petrone[1], G. Cammarata[1]
[1]Department of Industrial Engineering, University of Catania, Catania, Italy

This study deals with a numerical investigation of the melting process of a PCM in a rectangular enclosure differentially heated. COMSOL Multiphysics is used in order to numerically solve Navier-Stokes and energy equations in the considered system. Adopting an enthalpy formulation, one ... Read More

Modelling of the Wool Textile Finishing Processes

M. Giansetti[1], A. Pezzin[1], S. Sicardi[1], G. Rovero[1]
[1]Politecnico di Torino, Torino, Italy

Within wool textile industries, a very important role is played by the so-called finishing processes, in which the textile substrate undergoes steam treatments to achieve the desired level of stabilisation and appearance. Process parameters, namely temperature and moisture content, are ... Read More

Modeling of the Material/Electrolyte Interface and the Electrical Current Generated During the Pulse Electrochemical Machining of Grey Cast Iron

O. Weber[1], A. Rebschläger[1], P. Steuer[1], D. Bähre[2]
[1]Center for Mechatronics and Automatization, Saarbrücken, Germany
[2]Institute of Production Engineering, Saarland University, Saarbrücken, Germany

The Pulse Electrochemical Machining is especially suitable for the precise production of complex geometric contours with high precision and high surface quality demands in series manufacturing. During this process, the negative structure of an electrode is copied to the workpiece without ... Read More

Effects Of The Microstructure Of Fibrous Media On Their Acoustic Properties

C. Peyrega, and D. Jeulin
Center of Mathematical Morphology, Mines ParisTech, Fontainebleau, France

This study is a part of the Silent Wall ANR project, to which the Center of Mathematical Morphology is associated. Its main objective is to build an acoustical and thermal insulating system for buildings, composed of fibrous materials. The material is composed of two phases: the fibrous ... Read More

Early Stage Melt Ejection in Laser Percussion Drilling

T. Eppes[1]
[1]University of Hartford, Hartford, CT, USA

Laser percussion drilling is widely used in the aerospace industry to produce cooling holes in jet engine components. This process is a thermal, contact-free process which involves firing a sequence of focused optical pulses onto a target material [1-4]. During each optical pulse, the ... Read More

Determination of the Mechanical Properties in the Avian Middle Ear by Inverse Analysis

P. Muyshondt[1], J. Soons[1], D. de Greef[1], J. Peacock[1], J. Dirckx[1]
[1]University of Antwerp, Antwerp, Belgium

The middle ear of birds is a fascinating mechanical system, as it contains only one bony ossicle, compared to three in mammals, yet its auditory performance is not substantially worse. Its design resembles some currently used middle ear prostheses, so the understanding of its working ... Read More

Particle Flow Control by Magnetically Induced Dynamics of Particle Interactions

F. Wittbracht[1], A. Weddemann[1], A. Auge[1], and A. Hütten[1]

[1]Department of Physics, Thin Films and Physics of Nanostructures, Bielefeld University, Bielefeld, Germany

In this work, we show that dipolar magnetic coupling can be used to control the particle flow through microfluidic structures without changing the state of motion of the carrier liquid. Also no external magnetic gradient fields are employed; the total external magnetic force applied is ... Read More

A Study into the Acoustic and Vibrational Effects of Carbon Fiber Reinforced Plastic as a Sole Manufacturing Material for Acoustic Guitars

J. O'Donnell[1], G. McRobbie[1]
[1]University of the West of Scotland, Paisley, Scotland, United Kingdom

This study will research a modern design of acoustic guitar by analysis of the vibrational modes. The guitar that will undergo testing has been provided by Emerald Guitars and is solely constructed using Carbon Fiber Reinforced Plastic (CFRP). With the use of COMSOL Multiphysics© the ... Read More
