Initiation of Explosives by Adiabatic Compression of their own Vapour

Initiation of Explosives by Adiabatic Compression of their own Vapour PREVIOUS work has shown that the sensitivity of liquid explosives to impact is greatly increased by the presence of minute gas bubbles1. The initiation is of a thermal nature and is due to the adiabatic compression and heating of the trapped bubbles. A simple method of including a gas space in an explosive is to spread it as a small annulus on a flat anvil. When this is struck with a flat hammer, the small amount of gas in the centre is trapped and compressed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Nature Springer Journals
