Design and Implementation of a Small UAV’s Pod Equipped with a Solid Oxide Fuel Cell

N. Briguglio [1], G. Giacoppo [1], O. Barbera [1], F. Cipiti [1], M. Ferraro [1], G. Brunaccini [1], L. Di Giovanni [1], N. Randazzo [1], E. Antonucci [1]
[1] CNR ITAE, Italy

Unmanned aerial vehicles (UAVs) have recently received great interest due to their great potential in both military and civil applications [1-4]. Testing and construction of UAVs is expensive and time consuming and a simulation approach can help to reduce cost for both design and tests. ... Read More

Laser Assisted Brazing of Titanium to Aluminum Alloy

[1] Laboratoire Interdisciplinaire Carnot de Bourgogne, Université de Bourgogne-Franche-Comté, Comté, France

Laser assisted brazing with Al-Si fillers in V-shaped groove configuration is a perspective method for joining of aluminum alloys to titanium. The present work introduces multiscale model that allows estimating diffusion process at titanium/melted zone interface in function of thermal ... Read More

Interface Phenomena for a Multifunctional Air-Water Micro-Particle Collecting and Filtering System

E. Lacatus [1], A. Tudor [1], G. C. Alecu [1],
[1] Polytechnic University of Bucharest, Romania

The confinement clean rooms used in industry are susceptible to higher count of particles per cubic meter of air after the usual work program. To decrease the economic and technological effects of particle concentration a micro-cleaning device was elaborated. A first approach of a 3D ... Read More

Effect of Groundwater Flow on the Subsurface Temperature within Crystalline Rocks of Southern Norway

Y. P. Maystrenko [1], O. Olesen [1],
[1] Geological Survey of Norway (NGU), Trondheim, Norway

The subsurface thermal regime has been investigated in boreholes from southern Norway. During the purely conductive 2D thermal modeling, the COMSOL Heat Transfer for Solids interface has been used to simulate heat transfer by heat conduction. COMSOL physics interfaces Heat Transfer in ... Read More

The reduction of energy consumption in the building sector (nearly 40% of the energy consumption in Europe) is a real challenge to achieve the objective of the “2020 European climate and energy package”. In recent years, great interest is observed for the Stirling thermoacoustic ... Read More

Modeling and Simulation of Hydration Operation of Date Palm Fruits Using COMSOL Multiphysics

S. Curet [1], A. Lakoud [2], M. Hassouna [2]
[1] L’UNAM Université, ONIRIS, CNRS, GEPEA, Nantes, France
[2] Ecole Supérieure des Industries Alimentaires de Tunis, Tunis El Khadra, Tunisie

The control of the hydration during the thermal process of dates is crucial in order to save energy and to obtain a good quality for the final product. In this work, a theoretical model was developed in COMSOL Multiphysics software to describe the mass transfer phenomena involved in this ... Read More

Multiphysics Modeling of Sound Absorbing Fibrous Materials

T. G. Zielinski [1]
[1] Institute of Fundamental Technological Research, Polish Academy of Sciences, Warsaw, Poland

Many of fibrous materials are very good sound absorbers, because the acoustic waves, which propagate in air and penetrate a fibrous layer, interact with the fibers so that the wave energy is dissipated. The dissipation is related to some viscous and thermal effects occurring on the micro ... Read More

Virtual Modeling of Thermo-Physiological Comfort in Clothing

P. Van Ransbeeck [1], R. Benoot [1], B. Van Der Smissen [1]
[1] University College Ghent, Faculty of Science and Nature, Department of Mechatronics, Belgium

This publication aims to investigate conjugate heat and mass transfer around a clothed virtual manikin. This research can be performed at different scales: (1) at material scale where a piece of textile is investigated in 1D or 2D space or (2) at system level where a clothed cylindrical ... Read More

Keyhole Behavior During Spot Laser Welding

V. Bruyere [1], C. Touvrey [2], P. Namy [1]
[1] SIMTEC, Grenoble, France
[2] CEA DAM, Is-sur-Tille, France

The formation of porosities in spot laser welding depends on complex thermo-hydraulic phenomena. To understand and control these mechanisms, the COMSOL Multiphysics® software is used to model both the interaction and cooling stages of an isolated impact made with a Nd:YAG pulsed laser. ...
