Virtual Prototype Evolution by COMSOL Multiphysics® of a Continuous Flow Animal By-Products ABP Ohmic Sterilization Unit

R. Heslop[1]
[1]C-Tech Innovation Ltd., Capenhurst, Cheshire, UK

Ohmic heating (Joule heating) is a volumetric heating technology which can effectively process almost any pumpable fluid with extremely high energy efficiency (>95%). This is particularly useful for very thick fluids, those that burn on to hot surfaces and those with high solids content ... Read More

Acoustic and Flow Analysis to Reduce Boiler Hum

Th. B. J. Campmans[1],
[1]LBPSIGHT, Nieuwegein, The Netherlands

A installation caused severe hum, with 30 Hz as dominant frequency, causing serious annoyance. The acoustic study showed resonances around 30 Hz. Poor flow conditions existed at the inlet and outlet of the forced draft fan. Flow patterns were studied using CFD. Both the inlet and ... Read More

3D Acoustic Streaming Field in High-Intensity Discharge Lamps

B. Baumann[1], J. Schwieger[1], M. Wolff[1], F. Manders[2], J. Suijker[2]
[1]Hamburg University of Applied Sciences, Hamburg, Germany
[2]Philips Lighting, Turnhout, Belgium

High-intensity discharge lamps will in the foreseeable future be important light sources despite a growing market share of LEDs. Cost and energy efficient high frequency (300 kHz) operation is hampered by the excitation of acoustic resonances inside the arc tube, which results in low ... Read More

A 2D Model of the Flow in Hydrocyclones

B. Chinè[1], F. Concha[2], M. Meneses G.[3]
[1]School of Materials Science and Engineering, Costa Rica Institute of Technology, Cartago, Costa Rica
[2]Department of Metallurgical Engineering, University of Concepcion, Concepcion, Chile
[3]School of Production Engineering, Costa Rica Institute of Technology, Cartago, Costa Rica

Hydrocyclones are industrial devices used as processing units in fluid and particle technology. A hydrocyclone is an apparatus consisting of a cylindrical or a cylindrical-conical body with a tangential or involute entrance to admit the fluid inside. There are also two opposite exits, ...

Modeling of Expanding Metal Foams

B. Chinè[1,2], M. Monno[3]
[1]Laboratorio MUSP, Macchine Utensili e Sistemi di Produzione, Piacenza, Italy
[2]School of Materials Science and Engineering, Costa Rica Institute of Technology, Cartago, Costa Rica
[3]Politecnico di Milano, Dipartimento di Meccanica, Milano, Italy

Metal foams are interesting materials with many potential applications. They are characterized by a cellular structure represented by a metal or metal alloy and gas voids inside (Fig.1). A common metallic cellular material is aluminum foam which can be produced metallurgically by heating ... Read More

Numerical Modeling of Sampling Airborne Radioactive Particles Methods from the Stacks of Nuclear Facilities in Compliance with ISO 2889

P. Geraldini[1]
[1]Sogin Spa, Rome, Italy

The main objective of this study is to verify the compliance of an ongoing nuclear facilities stack design with the ISO 2889 requirements, during normal and off-normal conditions. In particular, with the numerical simulations, they have been identify well-mixed sample locations along the ... 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

Control of Real Distributed Parameter Systems Modeled by COMSOL Multiphysics® Software

C. Belavý[1], G. Hulkó[1], S. Lipár[1], B. Barbolyas[1]
[1]Institute of Automation, Measurement and Applied Informatics, Faculty of Mechanical Engineering, Slovak University of Technology in Bratislava, Bratislava, Slovak Republic

In the paper, first a basic concept of the engineering approach for modeling and control of distributed parameter systems (DPS) based on interpretation of controlled systems as lumped input and distributed output systems (LDS) is introduced. Next, FEM modeling of temperature fields in ... Read More

Traveling Plasma Wave Levitation of Objects Supported by Coanda Effect

R. Eisenschmid[1]
[1]OPTIMA pharma GmbH, Schwäbisch Hall, Germany

Electrostatically excited plasma waves can induce a “plasma wind” in the surrounding media or air. The lifted object has a shape of a flying saucer, just for better illustration. A travelling plasma wave propulsion requires a pre-ionized media around the surface and a travelling ... Read More

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 ... Read More
