Abstract

The vaporization of porous materials (especially internal vaporization of skeleton) has been largely ignored in studies of laser heating and processing of materials. The loss of energy associated with the vaporization process would keep the internal temperature of material from rising. In this paper the author presents the results of the computation of the heat losses for two different models of porous media: the sand and the pores' tree model. In his calculation the author uses the thermophysical parameters of gypsum slurry. In the first step a numerical simulation is carried out for the vaporization of solid skeleton and mass transport of vapor (without the viscosity of vapor), only. Then the water on the pore's wall was taken into account.
