Abstract
In this work, the thermodynamic method is presented of resolve of the equilibrium state of a reactive non-ideal heterogeneous system. The ways are described of application of the method for determination of parameters of combustion, explosion and detonation of high energetic materials. The code called ZMWNI is presented which is numerical application of the method. The main algorithm of the code and means of its use are described. Results of calculations by the use of ZMWNI and CHEETACH codes are compared. Equilibrium calculations of parameters of combustion, explosion and detonation for some explosives are performed as well as isentropes of products expansion and detonation energy are estimated. Chemical inertness of a one of components of explosive mixture as well nonappearance of heat exchange between the component and the detonation products are assumed in the non-equilibrium calculations. At the end, some calculated detonation characteristics are compared with experimental data.
