摘要微乳化柴油（例如阻燃抑爆柴油、阻燃柴油）的阻燃抑爆性能是安全应用和广泛推广微乳化柴油过程中不得不面对的现实问题。本文以阻燃柴油、阻燃抑爆柴油和普通柴油作为研究对象，在激波作用下分析三种柴油的抛撒雾化差异、静止状态下火球参数以及撞击后火球参数，得到微乳化柴油的阻燃抑爆性能。主要内容及结论如下：
（1）在一定强度的激波作用下利用高速摄像机捕捉油膜的雾化过程。通过对比分析发现：阻燃抑爆柴油和阻燃柴油的配方不同导致它们粘度也不同，雾化过程存在显著差异。粘度越大，越难雾化。它们的粘度从大到小依次为阻燃抑爆柴油、阻燃柴油和普通柴油，所以雾化由难到易依次为：阻燃抑爆柴油、阻燃柴油、普通柴油。18906
（2）在外场，分析三种柴油在静止状态下被引爆后（或撞击后产生爆炸）火球的参数得到微乳化柴油的阻燃抑爆特性。试验表明：在柴油中掺入适量的水有利于阻燃；不同配方柴油阻燃抑爆性能不同，需根据实际需求设计具体配方；进一步证实了粘度与微乳化柴油的阻燃抑爆性能有直接关系。

Title Study on flame-explosion suppression performance
of micro-emulsified diesel
Abstract
The flame explosion suppression performance of micro-emulsified diesels (e.g. flame explosion suppression diesel and flame-retardant diesel) have been studied for safety issues and wide applications in military and civil fields. The research objects of this paper are flame-retardant diesel, flame explosion suppression diesel and ordinary diesel. We have studied the cloud formation process of the three kinds of diesel, the different parameters of the fireballs occurs in the stationary state or post-collision. The flame-retardant explosion suppression performance of the three micro-emulsified diesels were compared with each other. The main results are shown as follows:
(1)Using high-speed camera to capture the snapshots of the cloud formation process after a shock wave in certain intensity. Through the experiments we can find: Since the three kinds of diesels are in different formulations, they have different viscosity. The greater the viscosity, the more difficult for the breakup of the droplets/jets. The flame explosion suppression diesel has the largest value of viscosity, following with flame-retardant diesel, and the ordinary diesel has the smallest value of viscosity. Therefore, the flame explosion suppression diesel is the most difficult one to breakup, and the ordinary diesel is the easiest to form the cloud after the shock wave.
(2)We also do the outfield experiments, where we ignite the three kinds of diesel in two different ways: static state and dynamic case. The results show that mixed with proper amount of water in the diesel in favor of flame-retardant, micro-emulsified diesel of different formulations have different flame explosion suppression performances, so that it needs to be designed with specific formulations based on actual demand. It further confirms the explosion suppression performances of micro-emulsified diesel have direct relationship with the viscosity.
