dispersed material

In this paper there are considered the basic methods of mathematical modeling that are used to describe the processes of convective, convective-thermal and active hydrodynamic drying of dispersed materials, taking into account the structure of individual object of drying.  They are described from perspective of continuum mechanics, the theory of mixtures, statistical approaches, which allows taking into account the volume fraction of each phase, the layering of the structure of the object and their changes in the process of phase transitions and chemical transformations.

Experimental and analytical investigations of the heat transfer process during encapsulation of dispersed materials in quasi-liquefied state are presented. The heat-transfer coefficients for different types of materials have been determined during their heating depending on air rate.

Experimental and analytical investigations of mass exchange during dispersed materials encapsulating in quasi-liquefaction state are presented. The mass transfer coefficients during encapsulating have been determined for different dispersed materials depending on air rate.
