Lifetime of a multifront structure in overcompressed detonation waves in gases
Abstract
Manzhalei and Subbotin (1976) have observed a multifront structure of compressed detonation waves in a CH4 + 202 + 7Ar mixture in the presence of negative heat release. In the present paper, a physical interpretation of this phenomenon is proposed. A stability criterion for supercompressed detonations is derived, and the possibility, in principle, of the existence of a self-sustaining detonation in the presence of negative heat release is demonstrated.
