Formation of the Condensed Phase in a Metallized Solid Propellant Rocket Engine,

Abstract

A brief theoretical outline is given of phenomena leading to formation and growth of alumina particles. An attempt is made to predict the evolution of the condensed phase through its history, i.e. successively in the combustion zone, in the combustor and in the nozzle. In the combusion zone, which appears to be rather thin, particles are formed very early, either in the vapor phase or on the surface of aluminum particles. In the combustor, condensed and gaseous phases are approximately in equilibrium, and particle growth is due to turbulent diffusion and acoustic effects. A schematic analysis of the distribution of the condensed phase in the nozzle inlet section is presented.
