In the present work, a two-dimensional numerical model of heat and mass transfer for the convective drying process of multilayer ceramic mould system was developed. The governing system of fully coupled non-linear partial differential equations describing the process was derived from a mechanistic approach. A formulation including hygrothermal and moisture transport in soil was adopted as the basis for further development in this work. For validation, the calculation results for drying of a ceramic material (brick) showed that the model presented is in a good agreement with other studies that have been reported previously in the drying porous material. Further application is illustrated through the drying of a ceramic shell layer under conditions that are relevant to shell manufacture in the investment casting process.
