A Multiphase Model to Analyze Transport Phenomena In Convective Drying

S. Curcio, and M. Aversa
Department of Engineering Modelling, University of Calabria, Rende, Italy

In the modern food industry one of the most important problems to face is to preserve products from deterioration: a widely used solution is the convective foods drying. Drying is based on a simultaneous transfer of both heat and water that takes place when dry and warm air flows around a moist and cold food sample. The aim of the present work is the development a fundamental multiphase approach ...

COMSOL Assistance For The Determination Of Pressure Drops In Complex Microfluidic Channels

J. Berthier, R. Renaudot, P. Dalle, G. Blanco-Gomez, F. Rivera, P. Caillat, and V. Agache
CEA-LETI, Grenoble, France

With the current trend towards always more complexity associated to more functionalities in biotechnological systems, it is required to know with accuracy the pressure drop in the circuitry of microfluidic systems. In general, a full three-dimensional calculation is not tractable due to the limited capacity of the computers. However, computational models can help to produce pressure drop ...

Deformation Behavior Of A Liquid Droplet Impacting A Solid Surface

[1]Laboratoire des Sciences des Procèdes Céramiques et de Traitements de Surface SPCTS, Limoges, France
[2]Laboratoire de Mécanique des Fluides et Energétique LMFE, Marrakech, Morocco

The quality of coatings obtained by means of thermal spraying depends strongly on the mechanism of the interaction between the molten droplets and the surface to be covered. The aim of the present study is to simulate the impact of a droplet onto a substrate, in order to have a good understanding of the dynamics of droplets impact. In this study, the process of droplet spreading is described; ...

ComsolGrid – A Framework For Performing Large-Scale Parameter Studies Using COMSOL Multiphysics and Berkeley Open Infrastructure for Network Computing (BOINC)

C.B. Ries, and C. Schröder
University of Applied Sciences Bielefeld, Germany

BOINC (Berkeley Open Infrastructure for Network Computing) is an open-source framework for solving large-scale and complex computational problems by means of public resource computing (PRC). In contrast to massive parallel computing, PRC applications are distributed onto a large number of heterogeneous client computers connected by the Internet where each computer is assigned an individual task ...

Structural Analysis: Going Beyond Standard Load Cases

I. Kjelberg
CSEM sa, Switzerland

Dr. Ivar Kjelberg is Senior Project Manager for Mechatronics in the Systems Engineering Division of CSEM SA in Neuchâtel, Switzerland. He obtained the diploma as \"Ingénieur Physicien\" from the Ecole Polytechnique Fédéreale EPFL in Lausanne, Switzerland in 1979, and a PhD at the local Institute for Plasma Physics (CRPP-EPFL) in 1986. He started his career at CSEM in 1988 and has since occupied ...

Numerical Simulation of a Building Envelope with High Performance Materials

[1]Civil and Transport Engineering Department, Norwegian University of Science and Technology, Trondheim, Norway
[2]Department of Architectural Design, History and Technology, Norwegian University of Science and Technology, Trondheim, Norway

Simulation tools for building physics problems play an important role in design and understanding the behavior of energy efficient buildings. There are different tools available for simulation of these problems, but each simulation tool has its own advantages and limitations. In this paper, a heat transfer problem in an exterior building wall with high performance materials has been simulated in ...

Finite Element Model of a Ferroelectric

P.R. Sainz, A.I. De Andrés Rubio, and A.L. Dorado
Departamento de Electrónica, Escuela Politécnica Superior, Universidad de Alcalá, Alcalá de Henares, Madrid, Spain

Ferroelectric technology continues to attract significant interest due to its wide range of applications (capacitors, nonvolatile memories, accelerometers ...). In this work we present a finite element model of a ferroelectric. Piezoelectric and ferroelectric matrix are included. The coupling between the piezoelectric and ferroelectric parameters be introduced formally using a thermodynamic ...

Modeling of Vickers indentation of TiAl alloys

G. Maizza, and R. Cagliero
Politecnico di Torino, Corso Duca degli Abruzzi 24, Torino, Italy

Instrumented indentation is increasingly used as an alternative non-destructive test method to measure mechanical properties of small volumes of materials. In this work, the instrumented indentation test is applied as a non-destructive method to assess the mechanical properties of TiAl components during the setup of a real production process. This study is a preliminary contribution devoted to ...

Flow Induced Oscillations of Marine Risers with Wake Interference

F. Van den Abeele, and J. Vande Voorde
OCAS N.V., J.F. Kennedylaan 3, Zelzate, Belgium

With offshore oil and gas exploration and production moving into ever deeper waters, the suspended length of marine risers (transporting hydrocarbons from the seabed to the surface) can easily exceed 3000 meters. One of the major design requirements for risers in (ultra) deep water is to limit the fatigue damage caused by vortex induced vibrations (VIV). Even moderate currents can induce vortex ...

Finite Element Simulation of Shear Wave Propagation Induced by a VCTE Probe

[1]Institut Telecom, Telecom ParisTech, Paris, France
[2]Echosens, Paris, France

The Fibroscan® (Echosens, Paris, France) device based on vibration–controlled transient elastography (VCTE) is used to non– invasively assess liver stiffness correlated to the hepatic fibrosis. Stiffness is quantified by measuring the velocity of a low–frequency shear wave traveling through the liver, which is proportional to the Young’s modulus E. It has been demonstrated that E is highly ...
