Drying Simulation of Ceramic Shell Build Up Process

Abstract

In this work, a two-dimensional numerical model for the convective drying process of ceramic shell layers was developed. The governing system of fully coupled non-linear partial differential equations describing the process was derived from a mechanistic approach along with the implementation of continuum model. The most extensive formulation of the material used in many hygrothermal and soil transport investigation was adopted as the basis for further development in this work. Two examples comprising one dimensional brick drying and shell drying are solved to validate and demonstrate robustness of the approach. Validation within a one dimensional framework showed that the model presented is in a good agreement with other studies that have been reported previously in the drying of porous material. A two layers case study which illustrate the drying of ceramic shell layers are compared and contrasted against experimental data on shell drying, showing good agreements.
