The mass transfer in the process of drying of deformable porous bodies was theoretically investigated and the corresponding
mass-transfer equation was analytically solved. On the basis of experimental data on the drying of porous materials, the ill-posed
inverse problem on determination of the region of regular change in the effective diffusion coefficient and in the porosity
of a porous-material layer with time was solved. 相似文献
