DEVELOPMENT OF CERTAIN ASPECTS OF THE
A. V. LUIKOV HEAT- AND MASS-TRANSFER THEORY

UDC   536.2

It has been proposed that A. V. Luikov's system of heat- 
and mass-transfer equations be supplemented with balance differential 
equations of change in the temperature and degree of saturation of 
a medium with its motion in the material for an a priori unknown character 
of their change. The approach to determination of the relative coefficient 
of thermal diffusion, the criterion of phase transition, and the value 
of the Fo number for the beginning of the stage of a regular regime 
of a one- and two-dimensional plate and to evaluation of the notion 
of the "soft" and "hard" processes of drying has been refined. The 
method of allowance for the multidimensionality of a body has been 
developed. The practical absence of the influence of moisture exchange 
on heat exchange in drying has been proved.
