Modeling of internal diffusion mass transfer during filtration drying of capillary-porous material

The article presents the results of theoretical and experimental studies on the determination of the coefficients of internal diffusion of moisture from capillary-porous materials of plant origin during filtration drying, in particular, beet pulp, a by-product of sugar production.  A model based on the solution of the internal diffusion differential equation with the corresponding initial and boundary conditions were used to find the internal diffusion coefficient. 

The heat-and-mass transfer during filtration drying of feedstock for slag gravel production. Research of change of temperature of thermal agent is on height of layer of material

In the article the results of experimental and theoretical researches are presented heat- and mass-transfer during the filtration drying of feedstock for slag gravel production. Time-history of temperature of thermal agent is experimentally investigational on the height of layer of dry and moist raw material materials and dependence of speed of moving of mass-transfer zone is certain on a temperature.
