Abstract

In the present work, a two-dimensional numerical model of heat and mass transfer for the convective drying of ceramic porous 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. The calculation results for drying of a ceramic brick showed that the model presented is in good agreement with other studies that have been reported previously in the drying of porous material. Further investigation on the shell drying agrees well with the most drying mechanism of ceramic porous body. The influence of material parameter on the drying profile is taken into consideration by carrying out some investigation on the material sensitivity study.
