Numerical Study on Shear Horizontal Electromagnetic Acoustic Transducers for Generation of Ultrasonic Guided Waves for Absorber Tubes used in Concentrated Solar Plants

L. Cheng[1], A. Mohimi[1], M. Kogia[1], V. Kappatos[1], C. Selcuk[1], T.-H. Gan[1]
[1]Brunel Innovation Centre, Brunel University, Uxbridge, UK

Absorber tubes are one of the most critical components of parabolic trough Concentrated Solar Plants, which is very likely get damaged such as crack and mass loss. Therefore, the monitoring of their structural health via Non-Destructive Testing (NDT) techniques is regarded as essential ... Read More

On the Influence of Cancellous Bone Structure upon the Electric Field Distribution of Electrostimulative Implants

U. Zimmermann[1], R.Bader[2], U. van Rienen[1]
[1]Institute of General Electrical Engineering, University of Rostock, Rostock, Germany
[2]Department of Orthopaedics, University Medicine Rostock, Rostock, Germany

Since the 1980s, the accelerating effect of electromagnetic fields on bone regeneration is used to treat complicated fractures and bone diseases. At the University of Rostock, an electrostimulative hip revision system is developed, basing on the method of Kraus-Lechner. This method ... 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

Three-Dimensional Thermal Modeling of Temperature Variation in Concrete Box-Girders Using COMSOL Multiphysics®

S. Abid[1,2], N. Tayşi[1], M. Özakça[1]
[1]Gaziantep University, Gaziantep, Turkey
[2]Wasit University, Kut, Iraq

The COMSOL's Heat Transfer module was used in this study to evaluate the temperature distribution in concrete box-girders subjected to exterior thermal conditions. The included thermal loads were air temperature, wind speed in addition to solar radiation. Moreover, the reflected ... Read More

Influence of Air Gap Length and Cross-Section on Magnetic Circuit Parameters

A. Polit[1], R. Jez[1]
[1]ABB Corporate Research Center, Krakow, Poland

The air gap is one of the most crucial part of magnetic circuits, especially in high-power inductors. It significantly modifies the parameters of magnetic devices by increasing the saturation current, linearizing B-H curve of magnetic circuit and causing a decreasing in the inductance. ... 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

Acoustic Wave Propagation in Water Filled Buried Polyethylene Pipes

T. Graf[1], T. Gisler[1], P. Sollberger[1], O. Schaelli[1]
[1]School of Engineering and Architecture, Lucerne University, Horw, Switzerland

Axisymmetric acoustic waves propagating along buried water pipes have been investigated by FEM and experimentally. Universal dispersion relations of the fundamental mode were obtained as a function of the standard dimension ratio SDR and of the material surrounding the pipe (soil, air). ... Read More

Modelling of Heat and Moisture Transport in a Corrugated Board Stack

M. Xynou[1]
[1]KTH Royal Institute of Technology, Stockholm, Sweden

Corrugated board is produced on a machine where the corrugated medium is glued between two flat paper surfaces, the liners. The board is cut into sheets and stored in a stack until suitable moisture content has been reached. The sheets are then cut and creased into blanks for the ... Read More
