摘要
利用挂滴装置研究了含能液滴ＬＰ１８４６在高温４４０～６２０℃、高压１．５２～３．５５ＭＰａ环境下爆裂性燃烧的规律。给出液滴从受热到爆裂性燃烧的时间序列照片，并定量测试液滴直径随时间的变化关系以及着火延迟期。初步分析了液滴爆裂性燃烧的机理，即液相化学反应。最后建立了液滴着火延迟期的工程计算模型，其计算值和实验数据吻合。
The properties of explosion combustion of energetic droplet LP1846 in hot(440～620℃) and high pressure(1.52～3.55 MPa) ambient have been investigated by use of suspended droplet apparatus. Time series photopraphs of the droplet from heating to explcaion combustion are given. Ignition delay time and relation of the droplet diameter as a function of timeare also measured quantitatively. The mechanism of explosion combustion of the droplet is discussed tentatively. An engineering calculation model on ignition delay time of the droplet is proposed. The calculated values agree with the experimental data.
