Particle migration using local variation of the viscosity (LVOV) model in flow of a non-Newtonian fluid for Ceramic tape casting
Chemical Engineering Research and Design, 2016Co-Authors: Masoud Jabbari, Jon Spangenberg, Jesper Henri HattelAbstract:In this paper, the migration of secondary particles in a non-Newtonian Ceramic Slurry in the tape casting process is investigated with the purpose of understanding the particle distribution patterns along the casting direction. The Ostwald-de Waele power law model for the non-Newtonian flow behaviour is assumed in the simulation of the Ceramic Slurry flow. A local variation of the viscosity (LVOV) model as a function of the particle volume fraction is introduced and taken into account in the advection and the settling of the particles in the flow field. The results show that using the LVOV model changes the particle distribution pattern from being a constant distribution to a semi-layered one. The presence of such layered structure is highly affecting the subsequent sintering process, which in turn causes anisotropic shrinkage of the dried tapes. Moreover, it is found that increasing the substrate velocity (casting speed) leads to a more uniform distribution of the particles inside the Ceramic Slurry, in which case the shear induced particle migration is dominating over the gravity induced one.

An evaluation of interface capturing methods in a VOF based model for multiphase flow of a non-Newtonian Ceramic in tape casting
Applied Mathematical Modelling, 2014Co-Authors: Masoud Jabbari, Jesper Henri Hattel, Regina Bulatova, Christian R.h. BahlAbstract:The aim of the present study is to evaluate the different interface capturing methods as well as to find the best approach for flow modeling of the Ceramic Slurry in the tape casting process. The conventional volume of fluid (VOF) method with three different interpolation methods for interface capturing, i.e. the Geometric Reconstruction Scheme (GRS), High Resolution Interface Capturing (HRIC) and Compressive Interface Capturing Scheme for Arbitrary Meshes (CICSAM), are investigated for the advection of the VOF, both for Newtonian and non-Newtonian cases. The main purpose is to find the best method for the free surface capturing during the flow of a Ceramic Slurry described by a constitutive power law equation in the tape casting process. First the developed model is tested against well-documented and relevant solutions from literature involving free surface tracking and subsequently it is used to investigate the flow of a La0.85Sr0.15MnO3 (LSM) Ceramic Slurry modeled with the Ostwald de Waele power law. Results of the modeling are compared with corresponding experimental data and good agreement is found.
