Modeling of the interface behavior in tape casting of functionally graded ceramics for magnetic refrigeration parts / Masoud Jabbari in International journal of refrigeration, Vol. 36 N° 8 (Décembre 2013) 

Public ISBD [article]  in International journal of refrigeration > Vol. 36 N° 8 (Décembre 2013) . - pp. 2403–2409 Titre : Modeling of the interface behavior in tape casting of functionally graded ceramics for magnetic refrigeration parts Titre original : Modélisation du comportement de l'interface lors du coulage en bande des céramiques calibrées pour les composants utilisés dans le froid magnétique Type de document : texte imprimé Auteurs : Masoud Jabbari, Auteur ; Jon Spangenberg, Auteur ; Jesper Hattel, Auteur Année de publication : 2014 Article en page(s) : pp. 2403–2409 Note générale : Refrigeration Langues : Anglais (eng) Mots-clés : Magnetic  refrigeration;  functionally  graded  ceramics;  tape  casting;  fluid  flow Résumé : The main goal of this work is to study the multiple material flows in side-by-side (SBS) tape casting and analyze the influence of the different material properties, i.e. the density and the viscosity, on the interface between the fluids, since this is highly important for the efficiency of a graded configuration of the magnetocaloric materials. The Newtonian flow behavior with relatively high viscosity is assumed for each fluid and used in the simulation with a commercial CFD code (ANSYS FLUENT). The results show that the density difference does not affect the interface between the adjacent fluids, whereas the viscosity of the fluids plays the most important role in the behavior of the interface. Moreover, increasing the viscosity difference of the adjacent fluids, Δμ, leads to increasing the diffusive region between them. However, this can be counteracted by decreasing the velocity by the substrate.
