Abstract

One-dimensional heating process in a saturated porous medium with a bulk heat source when absorbed high frequency (101 - 103 MHz) electromagnetic wave energy is studied. It is suggested that at initial state the saturated (the second) component is a high-viscous liquid or solid. Under heating it is melted down, expanded, lost its viscosity and becomes flowable relating to an immovable solid body - the rock sceleton (the first component). On the basis of a mathematical model proposed for one-dimensional axisymmetric movement the main process features are analyzed and numerically investigated. It is shown that the size of a zone subjected to the heating may be significantly great in real conditions. Thus by varying different external factors the process dynamics and temperature, pressure and speed phase field distributions may be affected essentially.
