Sorokova N. Modelling of heat- and mass transfer at dewatering of porous bodies with the purpose of optimization of drying process.

The mathematical model, method and algorithm of calculation heat- and mass transfer and phase transformations at dewatering capillary - porous materials are stated which allow to calculate dynamics of change of volumetric concentration and pressure for each of components of the connected substance - liquids, pair and air, and also of temperature for system as a whole. Diffusive and diffusive-filtrational mathematical models and methods of their realization for research heat- and mass transfer, phase transformations and deformation processes at drying colloidal capillary - porous bodies are resulted. Results of numerical and physical modelling of dynamics and kinetics of drying of capillary - porous and colloidal capillary - porous materials are stated. Their comparison for an estimation of adequacy of the constructed mathematical models and numerical methods of calculation is carried out.
