In a previous report estimates were made of the post-detonation pressure and temperature when TNT charges detonate in a closed chamber at loading densities varying from 0.2 to 270 kgcu m. An important simplifying assumption was that reaction products other than C, CO, CO2, H2O and N2 could be neglected. For TNT this introduces no serious error as long as the post-detonation temperature remains below about 2900 K, i.e. for all loading densities except the range 0.3 to 1.2 kgcu m, where oxygen balance is nearly obtained. For explosives with a higher detonation energy eg RDX and PETN this simplification is advisable only for loading densities well below those corresponding to oxygen balance. The objective of the present report is to present a refined and more general approach to this problem, particularly in the sense that many more explosion products are considered.
