Abstract
The principles of calculation of the characteristics of both coarse and fine fractions of condensed combustion products formed at the propellant surface and evolving as part of the multiphase flow in the combustion chamber. The characteristics of the condensed products at the propellant surface are determined by modeling the processes involved in their formation using a decision-making system based on the ideology of expert systems. An evolution model under inhomogeneous flow conditions with the mutual influence of the characteristics of condensed and gaseous combustion products is developed to determine the characteristics of condensed products in the multiphase flow of combustion products. The developed tools allow the characteristics of condensed products to be determined depending on the propellant composition, characteristics of the propellant charge, and combustion chamber parameters. Parametric analysis of the developed models for conditions in a combustion chamber was performed.
