A Novel Wavelength Detection Method Based on Wavelength Absorption in Silicon

K. Zhang [1], Y. Audet [1],
[1] École Polytechnique de Montréal, Montréal, QC, Canada

A new filter-less method of detecting the spectrum based on wavelength absorption in silicon is proposed. Wavelength dependent absorption coefficient produces a unique excess carrier distribution. Thus the wavelength spectral information can be obtained by measuring the photon generated ... Read More

Seeding Distribution in the Channel of a Cell Culture Vessel

[4] Clemson University, Rhodes Engineering Research Center, Clemson, SC, USA

Conventional cell culture (CC) techniques are advancing significantly with a trend towards a mass production. While plating density (number of cells per volume of culture medium) plays a critical role for some cell types, the initial distribution of these cells is affected by the actual ... Read More

Use of COMSOL Multiphysics® for IAQ Monitoring in Cleanrooms

G. Petrone[1], C. Balocco[2]
[1]BE CAE & Test, Catania, Italy
[2]Department of Industrial Engineering, University of Firenze, Firenze, Italy

High levels of Indoor Air Quality (IAQ) in Operating Theatres (OT) is an important issue in order to contribute in prevention of Surgical Site Infections (SSI). Despite of specific plant layouts are applied for OT ventilation (e.g. unidirectional flow), the effective use conditions can ... Read More

2D Axisymmetric Simulation of Pulsed Electrochemical Machining (PECM) of Internal Precision Geometries

This study presents investigations on a developed process design for manufacturing internal precision geometries by pulsed electrochemical machining (PECM) with help of multiphysics simulations. Therefore, a 2D axisymmetric transient model was created. The considered physical phenomena ... Read More

Numerical Analysis of Mass Transfer Rate in Droplet Flow at Microscopic Scales

S. Cito[1], T. Sikanen[1]
[1]Division of Pharmaceutical Chemistry and Technology, Faculty of Pharmacy, University of Helsinki, Helsinki, Finland

Droplet flow at microscopic scale is often used to enhance many pharmaceuticals and industrial processes (i.e. liquid–liquid micro-extraction, nanoparticle synthesis, slow reactions in microfluidic devices, etc.). In all these processes, the mass transfer rate, at the interface between ... Read More

Analysis of High-Frequency Thermoacoustic Instabilities in Lean, Premixed Gas Turbine Combustors

F. Berger [1], T. Hummel [1], P. Romero [1], M. Schulze [1], B. Schuermans [2], T. Sattelmayer [1],
[1] Lehrstuhl für Thermodynamik, TU München, Germany
[2] GE Power, Switzerland

Modern gas turbine systems for power generation are prone develop so-called thermosacoustic instabilities in the combustion chamber. Physically, these instabilities emerge as large amplitude pressure oscillations within the combustor, which are caused by constructive feedback ... Read More

Optimization of Jet Mixer Geometry and Mixing Studies

A. Egedy[1], B. Molnar[1], T. Varga[1], T. Chován[1]
[1]Department of Process Engineering, University of Pannonia, Veszprém, Hungary

The primary aim of using jet as mixer, like in case of other mixing devices, is to increase the heat and mass transfer between the phases. Beside the injection position the geometry of the jet mixer and the injection nozzle has a major effect on the injection. In our study COMSOL ... Read More

Simulation of Droplet Impingement on a Solid Surface by the Level Set Method

The dynamic behavior of droplet impingement on a solid surface is important to many engineering applications. This paper studied the dynamic behavior of a droplet impinging onto solid dry surfaces with different surface wettability using the COMSOL Multiphysics® software. The simulation ... Read More

Multiphysics Modeling of the Graphite Electrode Joint in Electric Arc Furnaces for Steel Recycling

N. May [1], M. Waldner [2],
[1] GrafTech International Holdings, Inc., Independence, OH, USA
[2] Case Western Reserve University, Cleveland, OH, USA

Electric Arc Furnaces (EAF) use graphite electrodes to strike an arc to melt scrap steel, recycling it for further use. These graphite electrodes oxidize and are consumed over time. To maintain operation new electrodes are attached to others via a joint of complex geometry and fed ... Read More
