Abstract
A computational and experimental study of the passage of a gasless combustion wave through a wedge-shaped inert barrier was performed. The stability of the transient combustion process to a change in the thermophysical, geometric parameters of the barrier and the energy-kinetic parameters of chemically active layers was studied. By the region of stable transient combustion process is meant the range of parameters in which the passage of the combustion wave through the contact boundary ends with the establishment of a steady-state mode of its propagation along the ignited composition. The dynamics of transient combustion under near-critical conditions of its existence was investigated.
