2.4.1.1 Detonation of Liquid Explosives in Free Space
When the explosion of liquid explosives occurs in free space, the detonation
reactions release large amount of energy in the form of pressure, and the gas
products expand rapidly to the surrounding. This results in the pressure of gas
products and temperature increase of local areas, which impacts the surrounding
media by high temperature and high pressure in the explosion direction, presses the
air and forms air shock waves. Following the further expansion of detonation
products, the air shock waves increase in their layer thickness. The pressure dis-
tributions of detonation products and air shock waves are shown in Fig.
