The Explosion Changing of Liquid Explosive Materials

Liquid explosives are noncompressible, and are different from condensed explosives. In the explosion, liquid explosives should be gasified first, later ignited. Once this abnormal combustion reaction becomes normal one, self-sustaining spread detonation follows. The explosion changes of liquid explosives have two classic forms combustion and detonation.

In contrast to the detonation of gaseous materials, the detonation process of explosives composed of energetic solid materials involves phase changes from solid to liquid and to gas, which encompass thermal decomposition and diffusional processes of the oxidizer and fuel components in the gas phase. Thus, the precise details of a detonation process depend on the physicochemical properties of the explosive, such as its chemical structure and the particle sizes of the oxidizer and fuel components. The detonation phenomena are not thermal equilibrium processes and the thickness of the reachon zone of the detonation wave of an explosive is too thin to identify its detailed structure.[i- i Therefore, the detonation processes of explosives are characterized through the details of gas-phase detonation phenomena.
