Abstract

Abstract

By focusing our concern on the effect of chemical reactions with detonation products, we have done research on the calculation of the quasi-static temperature of confined explosion. On the basis of the energy conservation, considering the chemical kinetic reaction process of the detonation products, the formula and calculating method of quasi-static temperature were proposed. A computation program was designed using C++ language, which was used to calculate the quasi-static temperature of the TNT confined explosion. Calculation results show that chemical reactions of the detonation products play a very important role in the calculation of the quasi-static temperature in confined explosions, and obviously the temperature varies with the charge volume ratios. Ours is an efficient technique to obtain a more accurate quasi-static temperature and calculate some other parameters of confined explosions.
