A model based study of the drying and shrinkage behavior of a ceramic green body

This work presents a 1D diffusion model to characterize the drying procedure of a ceramic slab with respect to shrinkage. The proposed mathematical framework is comprised of a set of partial–differential and algebraic equations along with moving boundary conditions. The model predictions are compared to experimental data from the literature and a good agreement is accomplished. Afterwards, the parameters of a desorption isotherm equation are …
