Phenomenon of Gaseous Adiabatic Compression of Powder in Explosive Compaction

Abstract:

This paper introducesan explosion experiment, in which the powder can be recollected100%. Based on the observations inside the recollected powder case,it can be confirmed that the very small amount of air in the space within the powderis concentrated in the bottom of the powder case,and consequently results in adiabatic compression. The compression energy of air gives rise tothe extra high powder temperature. A theoretical approach to the adiabatic mechanism was discussed and a rough estimationwas provided onthe degree of the increased temperature.
