摘要：

We have further developed the nonstationary mathematical model of two-phase filtration in an anisotropic porous medium - wood - by a fluid, taking into account the temperature dependence of its viscosity. The results of the calculations of the temperature and kinetics of wood impregnation under the action of vacuum and excess pressure for the problem of internal and external heat transfer are presented. The process of preservative impregnation of woodworks with a water-oil emulsion for various degrees of filling of the autoclave, including the maximum one, has been simulated. © 2004 Plenum Publishing Corporation.
