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 ... Mehr lesen

Dried Reagent Resuspension for Point of Care Testing (Analysis at the Patient Bedside)

M. Huet [1],
[1] Department of Biotechnology, CEA/Université Grenoble-Alpes, Grenoble, France

A microfluidic component was designed to collect blood from a finger prick by capillary flow and to perform biological analysis. It was used to perform ABO blood typing experiments in one step, the blood drop deposit, by agglutination of red blood cells (RBC) using embedded dried ... Mehr lesen

Coupled Numerical Modeling and Thermodynamic Approach for SiC Growth Process

J. M. Dedulle [1], K. Ariyawong [1], D. Chaussende [2]
[1] Univ. Grenoble Alpes, Grenoble, France
[2] CNRS, Grenoble, France

Silicon carbide (SiC) single crystals are industrially produced by the physical vapor transport technique. Apart from the geometry of the growth setup, there are two main process parameters that can be controlled: temperature and pressure. To support the development of the process, ... Mehr lesen

3D Modeling of Hydrogen Absorption in Metal Hydride Hydrogen Storage Bottles

R. Busqué [1], R. Torres [1], A. Husar [2], J. Grau [1]
[1] Escola Universitària d'Enginyeria Tècnica Industrial de Barcelona, Barcelona, Spain
[2] Institut de Robòtica i Informàtica Industrial CSIC-UPC, Barcelona, Spain

The storage of hydrogen as an absorbed element in metal hydride bottles is a promising technique for energy storage. In this work, a three-dimensional model of a charging process in a metal hydride container has been developed to simulate the absorption reaction and resultant heat and ... Mehr lesen

Quantification of Porosity Changes Due to Precipitation of Cement Materials with iCP

D. Sampietro [1], E. Abarca [1], M. Bayer [1], S. Jordana [1], J. Molinero [1], T. Tanaka [2], S. Hashimoto [2], T. Iwatsuki [3], H. Onoe [3], H. Saegusa [3]

[3] Japan Atomic Energy Agency, Gifu, Japan

The Japan Atomic Energy Agency (JAEA) is carrying out an URL (Underground Research Laboratory) project in Mizunami city, central Japan. The project is a purpose-built generic URL project that is planned for a scientific study of the deep geological environment in fractured crystalline ... Mehr lesen

Using COMSOL Multiphysics to Model Crust Development at the Surface of Whole Beef Meat Subjected to Hot Air Jet

J. Sicard [1], S. Portanguen [1], C. Chevarin [1], A. Kondjoyan [1]
[1] INRA Auvergne-Rhône-Alpes, Saint-Genès-Champanelle, FRANCE

Crust which develops at the surface of meat leads to reactions which affect food color, flavor and safety. Whole pieces of meat are only contaminated by microorganisms at their surface. Thus intense thermal treatment can inactivate pathogenic bacteria; however the associated high ... Mehr lesen

Models for Simulation Based Selection of 3D Multilayered Graphene Biosensors

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

At the forefront of a new generation of sensors graphene and graphene composite materials are intensively studied for medical and biosensing applications. The outstanding electrical, mechanical and quantum properties of graphene make them a promising material solution to overlap the ... Mehr lesen

Modeling Transient Adsorption/Desorption Behavior in a Gas Phase Photocatalytic Fiber Reactor

S. Denys [1], J. Van Walsem [1],
[1] Sustainable Energy, Air & Water Technology, Department of Bioscience Engineering, University of Antwerp, Belgium

Integration or retrofitting of photocatalytic air purifying units into HVAC (Heating, Ventilation and Air Conditioning) equipment is an interesting approach for abating indoor air pollution and removal of volatile organic compounds. An attractive possibility is the use of glass fiber ... Mehr lesen

Modeling of Non-isothermal Reacting Flow in Fluidized Bed Reactors

V. Orava [1], O. Souček [2], P. Cendula [1]
[1] Institute of Computational Physics, ZHAW, Winterthur, Switzerland
[2] Faculty of Mathematics and Physics, Charles University in Prague, Prague, Czech Republic

We investigate a prototype concept of a back-up electricity device where we use liquid formic acid (FA) to produce a mixture of carbon dioxide (CO2) and hydrogen (H2) which is used in a PEM fuel cell, Fig. 1. In the fluidized bed reactor the liquid FA is decomposed to a gaseous mixture ... Mehr lesen

Virtual Functional Product Development of a µ-Methane Steam Reformer

T. J. Kazdal [1], M. J. Hampe [1],
[1] Technische Universität Darmstadt, Darmstadt, Germany

A micro steam methane reformer is a complex product consisting of multiple units. For the virtual functional product development it is necessary to validate these sub models separately. Therefore a reactor was designed to analyse kinetics of chemical reactions. The reactor design is ... Mehr lesen
