- Abstract:
- The piston driver experimental system is used to perform a preliminary study on evaporation and combustion phenomena of kerosene and UDMH single fuel droplet in supercritical environment. The result shows that the kerosene or UDMH droplet will be vaporized in supercritical environment, it does not matter whether it is in liquid state or gel state. The spontaneous combustion phenomenon will happen when kerosene and UDMH droplet in the air supercritical environment. The spontaneous combustion appears in multi-dot simultaneous ignition at different position. It strongly resembles forest fire and lasts for along time. The combustion can be divided into four successive phases: evaporation, ignition, combustion prophase and combus
