NUMERICAL SIMULATION OF PHYSICAL AND CHEMICAL PROCESSES IN THE HEATED LAYER DURING COMBUSTION OF SOLID ROCKET PROPELLANT

摘要

The problem of the prediction of the direction of fast processes including the processes of burning and destruction of explosives is of great interest. However, it involves a great number of computing and system difficulties. At present, it is possible to solve individual problems, which allows a trustworthy prediction of fast processes via the successive use of the equations of quantum chemistry and molecular mechanics and the spatial-energy equations. In the given paper, phase distribution in a solid propellant, probable reaction centers and directions of their change are determined; kinetic parameters of reactions in a monopropellant (octogen) and phase boundaries in a compound propellant are estimated.
