ABSTRACT
Both natural and artificial porous bodies of different structure and composition are widely used in modern engineering and chemical technology. Therefore, the problem arises to describe more satisfactorily the properties of porous bodies and associated processes like evaporation, drying, wetting and capillary impregnation, filtration and capillary condensation. Contrary to general approach is based on physicochemical and microhydrodynamic analysis of transfer processes of gases, liquids and their vapors in pores. The field of surface forces acting here not only changes the fluid properties but influences the kinetics of mass transfer processes. In turn, forces acting among particles in a porous body depend on the fluid state, which results in changes of porous structure in the course of transfer processes. Structure peculiarities, equilibrium and properties of liquids in porous bodies are considered step-by-step in this monograph. Then various mechanisms of mass transfer are discussed.
