Özet:Заглавие с экрана
In this article new approach of simulating internal ballistics flows in SRM is considered. Two different phenomena should be taken into account for appropriate numerical simulation of internal ballistics problems: grain propellant regression and flow of combustion gases itself. The simulation is becoming more complicated as these two phenomena depend on each other: grain burning rate depends on flow parameters near the burning surface while flow parameters in SRM depend on current grain propellant position. Previous articles and theses considered complicated geometry of SRM grain but assumed only 1D flows of combustion gases. This assumption can be fulfilled for special types of SRMs but in general it may be far from truth. Thus, numerical schemes capable of simulating 2D and 3D gases flows are needed. This paper focuses on development, description and application of such schemes.
