Calculations wereperformed to illustrate the non-classical transport of heat and moisture. The effect of the heatflux density and the initial moisture content on water removal was also investigated. The resultsindicate that the non-equilibrium mass diffusion plays an important role during the very earlystages of moisture removal, especially at the surface of the medium. Away from the surface, thenon-Fickian model shows a delay in the reduction of the moisture content. The calculation resultsalso show that the initial moisture content of the medium has a considerable effect on waterremoval.展开更多
