ABSTRACT
This chapter is concerned with theories of deflagration of solid propellants. It explains to homogeneous propellants; different approaches to the analyses of their combustion process and discuss interface processes and then consider spatially distributed processes in different phases. With adiabatic combustion, departure from a complete control of m by the gas-phase reaction can occur only if the derivation of equation becomes invalid. There are a number of useful background references on solid propellants and their combustion. Polyvinylnitrate is a material that appears to burn in a process controlled by dispersed-phase combustion, and good agreement between theoretical predictions and experimental observations has been obtained. Heterogeneities in the solid's density, heat capacity, and thermal conductivity, heat of gasification, heat of combustion, and rate parameters may be considered. The combustion of black powder has been subjected to scientific scrutiny since antiquity. In general, gas-phase combustion appears to be of greater importance for heterogeneous propellants than for most homogeneous propellants.
