HEAT TRANSFER DURING HEAT TREATMENT AND DRYING OF MATERIALS IN ANALYTICAL CALCULATIONS OF NONSTATIONARY HEAT CONDUCTION

The results of using numerical solutions of the equations of nonstationary heat conduction in calculating the temperature of heat-insulating materials in the processes of their heat treatment and drying are presented. An approximation of nonlinear transport coeffi cients by linear coeffi cients is considered using the method of linearization and iteration. A simplifi cation of the equation of unsteady heat conduction is proposed using the method of piecewisestep approximation of transfer coeffi cients, taking into account the continuous change in the temperature of the material over minimal time intervals
