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.
