Thermal Energy Accumulation during Passage of a Combustion Wave through a Wedge-Shaped Obstacle.

A computational and experimental study of the passage of a gasless combustion wave through a wedge-shaped inert obstacle was performed. The stability of the transient combustion process to a change in the thermophysical and geometric parameters of the obstacle 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 its steady-state propagation regime in the ignited composition. The dynamics of transient combustion under near-critical conditions of its existence was investigated. [ABSTRACT FROM AUTHOR]
