Calculation of a detonation products composition and optimization of dynamic characteristics of mixed explosives

摘要

The mathematical model describing composition of products and dynamic characteristics at a detonation of a multicomponent mixture of condensed explosives is considered. The model consist of system of the equations concerning variables of possible composition and temperature taking into account laws of conservation, conditions of partial detailed balance for set of reversible reactions, semi-empirical functional dependence of energy-release realization coefficient. The numerical solution of these equations allows one to predict a relative detonation impulse, speed and pressure of a detonation of individual explosives and their mixes. On the base of proposed model, it is possible to state and solve a problem of detonation characteristics optimization. The application of the model for standard explosives with gross composition C_aH_bN_cO_dF_e is considered.
