Modelling of Heat and Mass Transfer in Food Products

[1]M.B. Andreasen

[1]Danish Technological Institute, Aarhus C, Denmark

The use of the finite element method for understanding and analyzing the freezing and drying processes of food products is in focus in this paper. The objective of this study is to develop a model that can predict temperature distribution and weight loss of food products during the ... Read More

FSI Analysis of Microcantilevers Vibrating in Fluid Environment

A. Ricci[1] and E. Giuri[1]

[1]Materials and Microsystems Laboratory (CHI-Lab), Politecnico di Torino, Torino, Italy

Cantilever vibration in fluid environment is probably one of the most common Fluid Structure Interaction problems in the field of Micro/Nano Electro Mechanical Systems. Usually the effect of fluid on cantilever oscillation is characterized in terms of mode resonance frequencies and ... Read More

Optimization of an Acoustic Waveguide for Professional Audio Applications

M. Cobianchi[1] and R. Magalotti[1]
[1] B&C Speakers S.p.a., Bagno a Ripoli, FI, Italia

In modern live sound reinforcement there is a growing use of line sources, obtained through the stacking of many loudspeakers with properly controlled wavefront shape. Thus the use of waveguides is mandatory in order to modify the shape and size of the wavefront exiting from professional ... Read More

[1]Gunytronic GmbH, St Valentin, Germany

The sensor type developed by Gunytronic uses corona discharge for measuring flow rates in exhaust streams of automotives, aircrafts and industrial plants. This paper will present the development of testing equipment used in laboratory for investigating physical relations on corona ... Read More

Helical Coil Flow: A Case Study

M. Cozzini[1]

[1]Renewable Energies and Environmental Technologies Research Unit, Fondazione Bruno Kessler, Povo, TN, Italy

Stationary flow configurations in curved pipes constitute an important subject from both the theoretical and the practical point of view. A typical application concerns the calculation of secondary flow effects on the thermal efficiency of heat exchangers. Motivated by a similar problem, ... Read More

Dynamic Crack Propagation in Fiber Reinforced Composites

C. Caruso[1], P. Lonetti[1], and A. Manna[1]

[1]Department of Structural Engineering, University of Calabria, Arcavacata di Rende, CS, Italy

A generalized model to predict dynamic crack propagation in fiber composite structures is proposed. The proposed approach is based on a generalized formulation based on the Fracture Mechanics approach and Moving mesh methodology. Consistently to the Fracture Mechanics, the crack ... Read More

Permanent Magnet Arrangements for Low-Field NMR

C. Horch[1], S. Schlayer[1], and F. Stallmach[1]
[1]Faculty of Physics and Earth Sciences, University of Leipzig, Leipzig, Germany

For low-field NMR (Nuclear magnetic resonance), NdFeB permanent magnet arrangements are proposed to provide the static polarizing magnetic field. Especially a parallel and a circular arrangement of the permanent magnets, iron yokes and small shim magnets were tested and improved by ... Read More

A Preliminary Approach to the Neutronics of the Molten Salt Reactor by Means of COMSOL Multiphysics®

V. Memoli[1], A. Cammi[1], V. Di Marcello[1], and L. Luzzi[1]
[1]Nuclear Engineering Division, Department of Energy, Politecnico di Milano, Milano, Italy

The Molten Salt Reactor (MSR), proposed along with other five innovative concepts of fission nuclear reactor by the Generation IV International Forum (GIF-IV), represents a challenging task from the modeling perspective because of the strong coupling between neutronics and thermo ... Read More

Level Set Method for Fully Thermal-Mechanical Coupled Simulations of Filling in Injection and Micro-Injection Molding Process

M. Moguedet[1], R. Le Goff[1], P. Namy[2], and Y. Béreaux[3]
[1]Pôle Européen de Plasturgie, Bellignat, France
[2]SIMTEC, Grenoble, France
[3]INSA de Lyon, Site de Plasturgie, Bellignat, France

In this work we tackle a more theoretical aspect of micro-injection molding, to better understand physics during the process, through numerical simulations of cavity filling. We developed a two phase flow approach by the use of COMSOL Multiphysics®. In a first step, a Level Set model ... Read More
