摘要：

Within the scope of the model, describing filtration combustion in the two-dimensional form, significantly non-one-dimensional regimes of wave propagation have been considered. It is assumed that the model takes account of the change in porosity of reacting components due to the change of their physical and chemical properties. The surface and by-layer combustion of a compacted sample in a gas has been described. Conditions have been determined, when a gas-proof layer appears on the surface of the sample. Dynamics of unsteady regimes for the front propagation has been investigated.
