Solution of an inverse problem for mass transfer in a drying process in a magnetic field

In this study, mass transfer in deformed porous materials is investigated theoretically and analytical solutions of mass transfer equations for investigated materials are derived. In order to determine the variation of porosity degree of the material versus time and to estimate the region where the variation of effective diffusion coefficient is regular, an inverse ill-posed problem is solved by considering the experimental data concerned with the drying of the porous material. The numerical calculations of concentration profiles and experimental results concerned with the drying of the materials in a magnetic field are given.
