  • Liquid fuel and RDX dust were dispersed at the same time in a detonation tube with an inner diameter of 200 mm and length of 5.4 m, and the cloud formed was initiated by high explosive from the bottom.Detonation pressure and velocity were obtained by the pressure measurement system, and photos and detonation cell were got by smoke trace technology.The results indicate that the 90# solvent oil-air cloud detonation pressure is 5-6 MPa, which means the 90# solvent oil can be used as a main fuel of fuel-air explosive.By adding isopropyl nitrate (IPN), its critical initiation energy can be lowered, and by adding RDX the detonation pressure and velocity can be raised.The calculation and experimental verification also found a link between the critical initiation energy and detonation cell size of multi-phase detonation which is similar with the gaseous detonation.
