- 摘要:
- 采用重活塞实验系统,对煤油和UDMH在超临界环境下的蒸发和燃烧现象进行了初步研究,结果表明:无论液态或者凝胶燃料,在超临界环境下均存在蒸发现象。在空气超临界环境下,煤油和UDMH均产生自燃现象。自燃呈现多点着火现象,类似于“森林火灾”模式,且持续时间较长。燃烧大致可分为蒸发、点火、燃烧前期和燃烧后期4个阶段。
- 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
