ZéolitesIndex. décimale : 620.11 Matériaux (propriétés, résistance) Résumé : By random growth method, this paper constructs isotropic porous media, anisotropic-1 porous media, and anisotropic-2 porous media, which have the same porosity but different micropore morphologies, and explores how the pore morphology affects the water vapor diffusion in the pores of porous media. The results show that: the random growth method can effectively reconstruct various porous moisture conditioning materials, and control their porosity and pore morphology; the equilibrium water vapor concentration and stabilization time of water vapor diffusion can effectively demonstrate the pore connectivity of porous media and the dynamic migration features of materials in the pores; the greater the change in the equilibrium water vapor concentration, the faster the stabilization of water vapor diffusion, and the better the pore connectivity of porous media.

Transfert d'humiditéIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : This paper deals with the transfer of heat and moisture in a pile of leathers with impermeable boundaries, which is caused by a jump in temperature at the boundaries. It is proved mathematically that changes in temperature take place in two "waves", with diffusion coefficients derived using the Henry theory of the simultaneous diffusion in porous sorbing materials, although the resulting relationships may be obtained only by use of a more common procedure under even more common assumptions than Henry's method. The results are compared with the experimental and theoretical data of Mitton and Dowsett obtained by use of an approximate solution with which they provide a good agreement. In conclusion, some important practical consequences of both the process and mathematical theory are mentioned. Note de contenu : - Introduction
