| Summary: | 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. |
