摘要
本文详细研究了几种碳氢燃料空气混合物(工业燃料C_5H_(8.68)和环氧丙烷)的爆轰反应特性。主要内容如下:在不同型号的激波管中进行了激波与水滴相互作用的研究并分析了激波对燃料的作用。研究发现水滴在激波作用下经历一个变形、破碎和雾化过程,只有水雾密度达到一定值,激波在水雾中的衰减才明显。在立式激波管中测试了工业燃料C_5H_(8.68)的临界起爆能、爆速、爆压、爆轰极限,得到了爆轰参数与当量比之间的关系;从爆轰反应是一个链反应机理出发,分析碳氢燃料的反应动力学过程。在常压和负压两种条件下测试了环氧丙烷(PO)在激波管中的胞格尺寸,分别测得了规则和不规则的胞格结构烟迹,得出了胞格宽度与当量比是“U”型曲线关系的结论;并分析了云雾爆轰的反应机理。对已有模型进行了改进,计算和分析了PO云雾爆轰的反应区和CJ面上的爆轰参数。
The detonation reactivity of some hydrocarbon-air mixtures such as industrial hydrocarbon C5H8.68 and propylene epoxide (PO) has been studied in this paper. The main works are as follows: The interaction of shock and water drops have been carried out in different-size shock tubes and it has been analyzed that shock acts on the hydrocarbon. With the action of shock, water drops undergo the process of deformation, fragmentation and atomization. The shock is decreased substantially only when density of water drops in air reaches a certain value. In the shock tube, the detonation parameters, such as critical initiation energy, detonation velocity, detonation pressure, detonation limitation and etc., have been measured and the relation is too obtained between detonation parameters and equivalence ratio. Chemical kinetics process of hydrocarbon fuel has been analyzed according to the chain reaction mechanism. The cellular structures width of PO in the shock tube in atmospheric pressure and negative pressure condition has been measured. Due to different condition, the figurations of the cellular structure obtained are either regular or irregular respectively. The relation between the cellular width and equivalence ratio is "U" shape. At last, the reaction mechanism of fuel spray in air is also analyzed. According to the modified model, the detonation parameters are calculated and analyzed in the reaction zone of PO spray in air and the CJ plane.
