In this paper, the drying modeling of roofing tiles was done using a "lumped" approach. In
other words, several forces that are influencing internal moisture transport are combined to
create effective moisture diffusivity. For this reason, the effective diffusivity coefficient was
added to Cranck's diffusion equation. In their earlier works, the authors published the solution
to the diffusion equation, which assumes that effective diffusivity is constant. It was
demonstrated that, particularly if shrinkage is not taken into account during the computation
stage, the simulated drying curves differ from the experimental results. The next step was to
ascertain the time-dependent effective diffusivity and to more precisely anticipate the drying
kinetic. The general functional relationship between effective moisture diffusivity and Fourier
number was first determined to fulfill this assignment. Experimental proof of the proposed
model was provided. Less than 3% of the outcomes from... the simulation and the experiment
deviated from each other. This was a resounding affirmation that effective diffusivity is not
constant during drying and that all internal transport mechanisms are observable in their timedependent
relation.
