Abstract
The planar one-dimensional and radially symmetric problems of the heating of a porous permeable medium saturated with a liquid by a heat supply through a boundary, which is impermeable for water or vapor, are considered. Self-similar solutions are constructed, which describe the propagation of the pressure field arising by virtue of thermal expansion or liquid boiling. The thermal shock dependence on heating intensity and porous medium parameters is investigated. The main part of the heat supplied through the boundary is found to be spent for the porous medium heating; the heat expenses for phase transitions are insignificant.
