| Summary: | In this work, a two-dimensional numerical model of heat and mass transfer for the
convective drying process of ceramic material was developed. The governing equations of fully
coupled non-linear partial differential was derived from the most comprehensive model with
considering the heat, moisture and gas transport along with the influence of microscopic pore
temperature gradient. Through validation the distribution of the measured variables and coefficients
(diffusivity) show a good agreement with the drying stage in porous material. |
