Zusammenfassung:The computer model of substances evaporation from non-uniformly heated porous medium is presented. The structure of the material is approximated by the system of cylindrical channels. Computer applications are implemented on the basis of FEM, which make it possible to predict the processes of condensation on the walls of capillaries. The synergistic features of the process are discussed, which are realized with a quadratic change of temperature. Kinetic transitions are found for three modes of migration of the volatile substance differing by the location of the condensation zones. The control dimensionless parameters of the kinetic transition are found. The phase diagram of realization of Ostwald ripening modes is built.
