Abstract
Abstract: The detonation parameters can be calculated using different methods with satisfying accuracy. Different approaches of detonation parameters’ calculations are used in many fields of engineering practice. The calculation results of detonation parameters using semi-empirical method and thermochemical model of detonation are presented in this paper. Both methods are applicable for CHNO high explosives, and with some approximations for CHNOAl high explosives. The calculated values using semi-empirical method have significantly better accuracy compared with the well-known Kamlet's method. The thermochemical model uses BKW equation of state with different sets of parameters. The detonation products are calculated using the free-energy minimization criterion. The computer program XW is developed, which is using both methods. The XW is developed using the Delphy® 6.0, and it can be used on personal computers with operating system WindowsXP®. The analyzed XW calculation results of detonation parameters have good correlation with experimental data.
Using the semi-empirical method, obtained average differences of calculation results for considered high explosives were 1.9% for detonation velocity and 4.5% for detonation pressure. In the calculations using thermochemical model, average differences of calculation results were 2.05% for detonation velocity and 5.73% for detonation pressure. In the case of most used high explosives for military purposes, the precision of calculation results is even higher.
