Multidimensional Modeling of a Toxical Molecule Formation during Food Frying

G. Carrieri, M. V. De Bonis, and G. Ruocco
CFDfood - DITEC, Università degli studi della Basilicata, Potenza, Italy

Heat related processing can have various effects on food and food ingredients. Besides the intended effects to improve safety and quality of the products, undesired changes, nutritional or toxicological, can also occur. In this area, acrylamide formation occupies an important role, as this molecule has been considered as a potential cause of cancer. The possibility that this molecule may be ...

Vibratory Study of the Soundboard of a Piano

P. Olivier, and J. Alenda
Enseeiht, Toulouse, France

In this presentation, we present our work on the vibratory study of the soundboard of a piano. Material parameters as well as thickness of the material is studied in detail.

Modelling AVO signals from laboratory acoustics and seismic (MASLAS)

R. Limacher, R. McHugh, and R. Westerman
Heriot Watt University, Edinburgh, Scotland

The Amplitude vs. Offset (AVO) technique infers the elastic properties of geological targets from pre-stack seismic data. AVO analysis significantly reduces the drilling risks for oil and gas exploration and development, particularly in the Gulf of Mexico. One strand of the current, EC-funded ADEMA Project is to evaluate AVO in coal-bearing strata. The target application areas are long-wall ...

Using COMSOL Multiphysics to Model Ground Heat Exchange

G. Jóhannesson
Div. of Building Technology, The Royal Institute of Technology, Stockholm, Sweden

In building physics it is a fact that a large part of the knowledge available from research is not applied in construction and design. The main reason for this is that the physics often include nonlinear field problems that are difficult to solve for the ordinary engineer. With a software that allows the combination of many different physics, the solvability of such problems increases.The ...

Robust Design of an LEM by Means of Interval Taylor Extension

B. De Vivo, P. Lamberti, and V. Tucci
Dept. of Electrical and Electronic Engineering, University of Salerno, Salerno, Italy

In this paper, the Robust Design of a Linear Electric Motor (LEM) is performed. A Robust Design is a set of nominal parameters that satisfies the customer constraints with uncertain parameters. In particular, it is possible to obtain the Most Robust Stationary Design (MRSD) of a Performance Function (PF) by looking at the minimum range of the Interval Extension of its Taylor series. Furthermore, ...

Modeling Flow Through Foam Channels

F. Rouyer, E. Lorenceau, and O. Pitois
Laboratoire de Physique des Matériaux Divisés et des Interfaces, Université Paris-est, Paris, France

We model the liquid transport in foam (i.e. drainage) by unidirectional flow transverse to a triangular planar area that represents channel (i.e. Plateau borders) cross-sections. Partial mobility of the interfaces is obtained balancing the bulk viscous stress with the surface viscous stress and a velocity equal to zero is imposed at the vertices. In liquid foams, the wedges of the channels are ...

Transport in reactive porous media containing biofilms

G. Debenest, Y. Aspa, and M. Quintard
IMFT, GEMP group, Toulouse, France

The objective of this presentation is the evaluation of effective bulk transport properties of reactive porous biofilm. We present our microscale model that accounts for both momentum and mass balances.

Mathematical Modeling of Atheroma Plaque Deformation using COMSOL Multiphysics

N. El Khatib1, S. Genieys1, M. Zine2, and V. Volpert1

The development of atherosclerosis leads to the formation of an atheroma plaque which takes place in the artery. This plaque is composed of two parts: a lipid deposit and a fibrous cap. The fibrous cap covers the lipid deposit and isolates it from the blood flow. The blood flow that circulates in the artery modifies the geometry of the atheroma plaque and can cause dangerous effects, such as a ...

Electro-Mechanical Modeling of Excitable Soft Tissues

Luciano Teresi
Assistant Professor
School of Engineering
Università "Roma Tre"
Rome, Italy

Cardiac muscle exists in two forms: the contractile myocardium and specialized conducting cells that spread the wave of depolarization throughout the chambers of the heart. Action potentials are initiated in the sinoatrial (SA) node, which serve as the “pacemaker” of the heart. In this presentation, this is investigated thoroughly with different examples and simulated results of ...

Modeling the Radiation of a Commercial Sensor, the Fish Fat Meter, in a Multilayer Biological Material

S. Clerjon
Centre INRA de Theix, St Genes Champanelle, France

The Fish Fat Meter sensor is used for in vivo measurement of intramuscular fat content in fishes. It is based on the propagation of a 2 GHz wave along a micro-strip line placed against the fish. It is used at INRA to select fat or lean fish in fish-farming studies. COMSOL Multiphysics has been used to perform 2D and 3D modeling in order to support recommendations to users of the Fish Fat Meter. ...
