An Analysis of the Synchronous Transport Phenomena Involved in Pasta Drying Process

G. Adduci1, E. Manoli2, E. Cardaropoli2, G. Coppola1, F. Petrosino1, S. Curcio1
1DIMES, Università della Calabria, Cosenza, Italy
2Barilla G. e R. Fratelli, Parma, Italy

This work is focused on the development of a physical-mathematical model capable of predicting the temperature and water content fields within a pasta sample which is exposed to a stream of drying air flowing under turbulent conditions. Therefore, the equations concerning the transfer of ... En savoir plus

Optimal Design of Baking Plates for an Inductive Wafer Baking Oven

Johannes Steinbach1, Lukas Jadachowski2, Andreas Kugi3, Andreas Steinboeck2
1Automation and Control Institute, TU Wien, Vienna, Austria
2Automation and Control Institute, TU Wien, Vienna, Austria, Christian Doppler Laboratory for Intelligent Process Control for High-Quality Steel Products, Automation and Control Institute, TU Wien, Vienna, Austria
3Automation and Control Institute, TU Wien, Vienna, Austria, Center for Vision, Automation & Control, Austrian Institute of Technology (AIT), Vienna, Austria

Baking is a central production step in the industrial production of edible wafers and waffles. The initially liquid batter is heated with a pair of metallic baking plates. Establishing a uniform and accurate temperature at the baking face (inner baking plate surface) is crucial for ... En savoir plus

Efficient Geothermal Cooling in Harsh Environments: A Combined Experimental and Modelling Approach

Mohammed Al-Azba1, Ahmed Abotaleb2
1Qatar Environment and Energy Research Institute, HBKU, Qatar Foundation, Doha, Qatar
2ICube Laboratory, Université de Strasbourg-CNRS, 67000 Strasbourg, France

In this work we present a novel approach to enhance energy efficiency in cooling intake air for air conditioning (AC) systems in harsh environments using geothermal energy. We developed a 3D finite element model to simulate the heat transfer between underground soils/gravels and cooling ... En savoir plus

Development of a Special COMSOL® Interface Based on an Alternative Model for Bentonite Re-Saturation

Michael Kröhn1, Lars Fromme2
1GRS gGmbH, Braunschweig, Germany
2Hochschule Bielefeld – University of Applied Sciences and Arts (HSBI), Faculty of Engineering and Mathematics, Bielefeld, Germany

Bentonite is a versatile material that is, among other things, envisaged in most countries worldwide for use in radioactive waste repositories to protect the waste canisters against groundwater. The thermo-hydro-mechanically (THM) coupled process of bentonite saturation is commonly based ... En savoir plus

Modeling of Thermal Load and Electric Fields in Microfocus X-Ray Tubes

Dr. Vladimir Burlaka1, Thorsten Fröba1
1X-RAY WorX GmbH, Siemensstraße 26, 30827 Garbsen, Germany

The thermal load on the system components is one of the technical problems in the development of microfocus X-ray tubes. To improve their stability in long-term use, it is important to understand the physical phenomena and their influence on the system stability and filament lifetime. To ... En savoir plus
