process of drying

In this article patterns of development of tension-deformed state of canillary–porous materials with variable heat-mechanic characteristics in the process of drying, depending on the characteristics of the environment, were resulted. The influence of the parameters of drying agent on the dynamics of stress in the wood was investigated on the basis of numerical experiment.

The mathematical model of heat and mass transfer in capillary-porous bodies for drying with taking into account the zone of evaporation movement is given in the work. The analytical solutions of nonlinear problems of heat and mass transfer for unsteady regimes of drying are received. The effect of duration of drying regimes on the temperature of phase transition in wood is investigated
