In the nuclear fuel cycle, fluorine is produced by the electrolysis of the molten salt KF-2HF. It is a complex process to study since hydrofluoric acid and fluorine are hazardous and highly corrosive. A 3D-model of a lab-scale fluorine electrolysis cell has been developed to increase ... 詳細を見る

Using Multiphysics for Detecting Atmospheric Ice Through MuVi Graphene - Atmospheric Icing Sensor

U. N. Mughal [1],
[1] Narvik University College, Norway

This paper is a preliminary design study to develop a hybrid atmospheric icing sensor which have an adequate potential to detect an icing event, icing type and icing rate together with icing load. The physics to detect icing event and icing type have been numerically understood using ... 詳細を見る

Coupled Heat and Mass Transfer Model to Simulate Hygrothermal Behavior of Bio-Based Materials

M. Asli [1], F. Brachelet [1], A. Chauchois [1], E. Antczak [1]
[1] Université d'Artois, Béthune, France

This poster presents a numerical modeling approach for hygrothermal behavior of bio-based materials. The mathematical model describes the heat and moisture transfer through a wall of bio-based materials. The studied wall is subjected to both convective heat transfer and moisture flux ... 詳細を見る

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 ... 詳細を見る

Thermal Conductivity of Composites: How COMSOL Revealed an Omission in a Classical Paper

P. Berne [1],
[1] University Grenoble Alpes, Grenoble, France

The initial motivation for this work was to explore the relationship between the shape of particles and the thermal conductivity of nanofluids or nanocomposites containing them. Since the possibility for manufacturing exotically-shaped particles is ever growing, it was thought useful to ... 詳細を見る

COMSOL Multiphysics® for Building Energy Simulation (BES) Using BESTEST Criteria

A.W.M. (J.) Van Schijndel [1], D. P. M. Jacobs [1],
[1] Eindhoven University of Technology, Eindhoven, Netherlands

Pioneering Computational Models for the Built Environment Energy performance is becoming more important in the build environment. With better insulated buildings, the possibility of moisture problems and thermal bridges increases. There for, it is not only important to determine the ... 詳細を見る

Temperature Propagation during Cell Stacking Processes for Lithium-Ion Cells

G. Liebig [1], P. Bohn [2], L. Komsiyska [1], S. Vasić [1]
[1] NEXT ENERGY EWE-Forschungszentrum, Oldenburg, Germany
[2] AUDI AG, Ingolstadt, Germany

A thermo-physical 3D model of a commercial Li-ion battery was developed and validated. Visualization of the temperature distributions inside a Li-ion cell during cell stacking processes were simulated. Critical temperature levels depend on position, duration and intensity of the thermal ... 詳細を見る
