Two-dimensional heat and mass transfer during drying of deformable media. (English) Zbl 1140.80004
A mathematical model consisting of two-dimensional heat and mass transfer in clay is analysed. An axis-symmetry clay solid is considered as an isotropic porous medium with no chemical reaction. A nonlinear convective-diffusive equation is developed for the moisture diffusion. An implicit finite difference scheme is used to solve the heat and mass transfer equations. As obvious, the temperature gradient within the clay is weak. No attempt is made to study the stability of the numerical scheme to solve the problem.
