HEAT AND MASS TRANSFER IN POROUS MEDIA: MASS TRANSFER IN THE PROCESS OF DRYING OF POROUS MATERIALS

摘要

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.
