Heat and Mass Transfer in Holed Ceramic Material Using Lumped Model

Abstract:

The drying is a thermodynamic process of simultaneous heat transfer and moisture removal of a porous material. Clay products when exposed to drying without control can suffer cracks and deformations, reducing its quality post-drying. Thus, this work aims to study the holed solid drying with arbitrary shape using the global capacitance method. Application has been made for the drying of clay products. The analytical solution of the governing equations was made using the method of separation of variables.Kinetic results for mass loss and heating of the material are presented and analyzed. It was observed that the moisture loss process occurs at a lower speed than the heating of the ceramic material because its thermal diffusivity is greater than the mass diffusivity and that the area/volume relationshipstrongly affects the phenomena of heat and mass transport.
