Convective Burning in Propellant Defects: A Literature Review

Abstract
This report presents a survey of literature describing the onset and development of convective combustion--one of the first steps associated with the transition of deflagration-to-detonation of solid propellants. It contains results from experiments using various single pore (or channel) geometry and porous bed geometry, as well as damaged propellant samples. A section describes the results from various analytical models as applied to single pore and porous bed geometries. Attributes that favor convective combustion are presented in the context of: attributes favoring gas flow into the defects, attributes favoring ignition of the pore surfaces, and attributes favoring acceleration of the convective front.
