Abstract
The study examines the modes of propagation of cellular infiltration combustion waves through a high-porosity layer of an energetic composition yielding condensed reaction products. Under conditions of instability, a planar infiltration combustion front breaks into individual exothermic reaction cells, which propagate through the heterogeneous mixture in the pulsation mode. Based on video records and theoretical analysis of the process, the dynamics of propagation of a pulsating cellular front is investigated. The dependences and mechanisms of transformation of cellular combustion modes are established. The evolution of a cellular frontal structure within a separate pulsation period is investigated.
