Metal agglomeration in solid propellants combustion part 2: Numerical experiments

This article is a continuation of the work (Rashkovsky, 1998). The solution method of equation of metal agglomeration in solid propellants combustion theory is suggested. It is based on statistical tests method (Monte Carlo method). Different agglomeration mechanisms have been investigated and agglomerates probability density function for different ammonium perchlorate (AP) particles spectra have been obtained, as well as dependencies of average mass agglomerates diameter upon average mass diameter of AP particles. II is shown, that mass agglomerates distribution is of polymodal nature, which corresponds to known experimental data. Effect of different factors on agglomerates dispersity has been investigated. This paper includes analysis of different calculated schemes. Besides, the peculiarities of Monte Carlo method applying and common recommendations, necessary for making new calculation models of the metal agglomeration process in composite solid propellants combustion are considered. The effect of different process parameters on the agglomeration intensity are investigated.
