The behavior of the vapor phase at boiling in a porous body was simulated with the help of a hybrid model based on the lattice Boltzmann method and the solution of the heat conduction equation. The boiling process is considered in a two-dimensional formulation in a model porous medium formed by a set of rectangular solid inclusions. The dynamics of the vapor phase rising through a porous body under the action of a buoyant force was studied depending on the parameters of the porous body structure. The influence of two neighboring bubbles on each other was investigated for vertical and horizontal arrangements of two adjacent heaters inside the porous structure. As a result, the phase pictures of the boiling process, the time dependencies of the effective heat fluxes from the heaters and the bubbles departure frequencies were obtained for various structural parameters of the porous body and the heaters configuration. An analysis of the results permits to identify the mechanisms of heat exchange intensification/degradation at boiling in a porous structure.
