Power law fluids and Bingham plastics flow models for ceramic tape casting

Abstract A generalized pressure flow is used as a basis for developing a flow model for ceramic tape casting with different types of fluids such as Newtonian, power law and Bingham plastics. The slurry flow is modeled as part of a pressure flow through an imaginary parallel channel. Analytical equations for the flow field are presented. Equations for obtaining velocity profiles and flow rates are included. These can be used to estimate the thickness of the ceramic tape to be cast. The formulations were validated by means of published data, the results of which are included in the paper. Finally, the effect of various process parameters on the size of the imaginary flow channel is studied.
