Abstract

We theoretically and experimentally investigated the effects of pore size distributions on heat and moisturetransfer in porous materials (B-1 and B-2) during drying. Experimental results showed that the mean moisture content of B-2 at the end of the surface evaporation period was lower than that of B-1 for the same gas flow conditions, and this value was affected by both the drying rate and moisture transfer properties of the material. From the critical moisture content of the experimental results, the moisture transfer coefficients of samples were estimated.
