Effective Thermal Conductivity of Composite: Numerical and Experimental Study

M. Karkri
Université Paris-Est, CERTES, Créteil Cedex, France

In this paper, thermal properties of composites are investigated numerically and experimentally. In the numerical study, finite-elements method in COMSOL is used to modelize heat transfer and to calculate the Effective Thermal Conductivity (ETC) of the composite for three elementary ...

Dynamic Model for Catenary Mooring: Experimental Validation of the Wave Induced Load

L. Martinelli[1], A. Spiandorello[2], P. Ruol[3], and A. Lamberti[1]
[1]DICAM, Università di Bologna, Italy
[2]Civil Engineer, Italy
[3]IMAGE, Università di Padova, Italy

This paper will present a numerical model based on COMSOL Multiphysics suited to simulate the dynamic response of a catenary mooring (or a submarine cable). In general, mooring lines are subject to a direct wave load (e.g. drag, inertia) in addition to the movement of the vessel to ... En savoir plus

Modelling and Analysis of Acoustic Emissions and Structural Vibration in a Wind Turbine

B. Marmo, and B. Carruthers
Reactec Ltd., Edinburgh, United Kingdom

The onshore wind turbine industry must overcome many technical, commercial, and environmental difficulties. A significant element for planning consent is operational noise. Acoustic limits are strictly enforced and can lead to near-neighbour complaints as well as contractual disputes. ... En savoir plus

Rheological Behaviour of Biphasic Material

P. Lamy-Bracq[1], J. Leroy[2], and C. Coulouarn[1]
[1]NEXTER Munitions, Bourges, France
[2]ENSI Bourges, Bourges, France

The rheological behaviour of a biphasic material is quite difficult to model because of the difficulties to represent the evolution of the space position of each solid particle in the solid matrix. The first part of this study consider an equivalent material by homogeneisation method. ... En savoir plus

Heat and Mass Transfer in Partially Frozen Food Material

B. Watzke[1], H. Deyber[1], and H. Limbach[2]
[1]Nestlé Research Centre, Lausanne, Switzerland
[2]Research Centre, Lausanne, Switzerland

The freezing curve of the food material was extracted from Differential Scanning Calorimetry experiments. A heat conductive model was generated in COMSOL, including the thermo-physical characteristics and the phase transition behavior. The resulting temperature-time evolutions at ... En savoir plus

Equation-Based Modeling: The Structural Contact Problem Solved by The Velocity Approach

O. Toscanelli, and V. Colla
Scuola Superiore S. Anna, Pisa, Italy

The contact between infinitely rigid body and deformable part is studied using the velocity as a dependent variable. A simple forging case is evaluated. The velocity approach is realized by means of using COMSOL with the Equation-Based Modeling. The contact model evaluated in this work ... En savoir plus

Simulation of Interaction of Low-Temperature Plasma with Immersed Solids

V. Hrubý, and R. Hrach
Department of Surface and Plasma Science, Charles University, Prague, Czech Republic

The computer simulation with COMSOL Multiphysics has become a widely used technique for the study of various problems in the field of plasma physics. Despite the increasing performance of computers, fully three-dimensional particle simulations still have got extremely high demands on ... En savoir plus

Material Flow around a Bobbin Tool for Friction Stir Welding

J. Hilgert, L. Hütsch, J. Dos Santos, and N. Huber
GKSS Forschungszentrum GmbH, Geesthacht, Schleswig-Holstein, Germany

This study presents an approach to model the material flow around a bobbin tool for Friction Stir Welding (FSW). In this CFD model the aluminum is treated as a highly viscous non Newtonian shear thinning liquid. The model is formulated in a 3D Eulerian frame. The temperature field and ... En savoir plus
