Abstract

In this research work, a computer code is developed to predict the DETONATION properties of HIGH EXPLOSIVES on the basis of the Chapman-Jouguet theory. A new free energy minimization scheme was employed to calculate the equilibrium composition of non-ideal and multiphase mixture of DETONATION products. The new minimization scheme is a variant of the Newton-Raphson algorithm. In the present work, the second derivatives of free energy are computed for non-ideal mixture. It is found that the developed algorithm calculates the chemical equilibrium properties more accurately than the FORTRAN BKW scheme which takes the second derivatives of free energy as equal to their values in a perfect gas mixture. The calculated DETONATION velocities and C-J pressures are compared with experimental data as well as the data reported from other thermo-chemical codes.The results are very promising.
